of the
Viceroyalty of Peru in 1680. Most of the future Viceroyalty of the Río de la Plata territory was part of the
Royal Audiencia of Charcas, though
Cuyo was in
Chile.
Project and creation of the Viceroyalty On 8 October 1773,
King Charles III asked the
Royal Audiencia of Lima and the
governor of Buenos Aires about the possibility of creating an
audiencia in
Tucumán. The
audiencias were supreme courts of justice that exercised some administrative functions over their territory, in collaboration with the
viceroys. A single Viceroyalty could have many
audiencias. Both Tucumán and Buenos Aires were part of the
Royal Audiencia of Charcas (along with much of the present-day
Argentina land), within the Viceroyalty of Peru. On 22 January 1775,
Viceroy Manuel de Amat y Junient answered the request with a different proposal: to create an
audiencia in Buenos Aires and a new viceroyalty, which included the Río de la Plata territories (such as Buenos Aires and Montevideo), and had its capital in
Chile. On 1 April 1776, the
German-born Portuguese general commander of
São José do Norte, Johann Heinrich Bohm, attacked the Santa Bárbara and Trinidad forts, and recovered the village of
Río Grande, which had been previously conquered by the Spanish governor of Buenos Aires
Pedro de Cevallos. This event made the king think about creating a viceroyalty with its capital on the Río de la Plata instead of Chile. In 1776, a military expedition to South America was being organised. The objective, according to King Charles III, was to recover the lost territory and punish Portugal. On 27 July 1776, Pedro de Cevallos, who at that time was governor of
Madrid, received a letter naming him commander of the campaign. Besides, on 1 August 1776 the king gave him control over the
Royal Audiencia of Charcas and the corrigimiento of Cuyo, as viceroy and general captain in order to facilitate the mission. When the expedition was finished, Cevallos had to resume its office as governor on Madrid and let the command of Charcas and Cuyo as it was before his arrival. Though theoretically temporary, this separate administration of these territories, with Pedro de Cevallos as viceroy, was the beginning of the new viceroyalty.
Pedro de Cevallos' military expedition Cevallos started its campaign with the objective of pushing Portugal to the east of the dividing line previously established by the
Treaty of Tordesillas. On 20 February 1777, the expedition —that consisted of 116 ships— disembarked on Santa Catalina Island, which surrendered on 5 March. Later, since they were not able to attack Río Grande due to weather conditions, the expedition headed to the south of the Banda Oriental (present-day Uruguay). On 4 June, the Portuguese governor of Colonia del Sacramento surrendered to Cevallos, and the city was destroyed. The campaign continued and captured the
Fortress of Santa Teresa and the Fort of San Miguel, advancing towards the population of Río Grande. Nevertheless, the offensive stopped when Cevallos was notified about peace negotiations between Spain and Portugal. On 1 October 1777, the
Treaty of San Ildefonso was signed by the two colonial powers. Portugal recognised Spanish sovereignty over Colonia del Sacramento and
San Gabriel Island. In exchange, Spain had to give up the Santa Catalina Island and Río Grande. Besides, Portugal gave Spain the
Fernando Poo and
Annobón Islands (nowadays part of
Equatorial Guinea).
Formal establishment Once the conflict with Portugal was finished, Cevallos arrived at Buenos Aires on 15 October 1777. He dictated the Auto de libre internación, allowing free trade of both products from Spain and the Indies, between Buenos Aires, Chile and Peru. Besides, since Potosí —land of the precious metals— was under his jurisdiction, on 8 July 1777 he had prohibited the delivery of unminted gold and silver to the Iberian Peninsula if it was not done through the Port of Buenos Aires. These measures affected the merchants from Lima, but were allowed by those from
Cádiz. On 27 October 1777, the king formalised the creation of the viceroyalty, ending its temporary nature. The reason behind this, in his own words, was that Lima was too far away from Buenos Aires; therefore having a separate viceroyalty was more efficient. The territory remained, but the viceroy was replaced shortly after. On 28 June 1778, Cevallos returned to Spain and handed over command to the new viceroy,
Juan José de Vértiz y Salcedo, as he was expected to do when the campaign was finished. He died on 28 December of that year.
Portuguese capture of the Misiones Orientales From 1801 to 1802, within the framework of the
War of the Oranges, the Misiones Orientales, which were part of the Political and Military Government of the Misiones Guaraníes, were captured by Portuguese forces and discontented Guaraní people. On 1 August 1801, the alliance occupied San Miguel Arcángel, and a few days later conquered the rest of the Misiones Orientales and the town of San Francisco de Borja. Other Portuguese forces took over the military posts between the
Piratini and
Jaguarão rivers: Batoví, the Fort of Santa Tecla and the Guardia of San Martín. In January 1802, they destroyed the Fort of San José, situated at the south border of the
Apa River in Paraguay. The King of Portugal accepted to return the conquered territories to Spain, but never did so. This loss, along with the loss of Paraguay in 1810, resulted in the narrow extension of present-day
Argentina in its northeastern corner, which belongs to the
Misiones Province.
British invasions In 1806, during the
Napoleonic Wars, the French Emperor
Napoleon Bonaparte established the
Continental System, a large-scale embargo against Britain. As Spain was allied with France, it obeyed the imposition and illegalised trade with the British; and though it kept occurring through the smugglers, it was more difficult. On the other hand, Britain was aiming to expand its influence and achieve new markets. The Río de la Plata was a good objective: it had a very important port, it wasn't protected by a professional army and it had a valuable treasure that couldn't be delivered to Spain due to the naval blockade established after the
Battle of Trafalgar. Besides, capturing it would later allow Britain to move forward to Potosí and take its precious metals. In June 1806, a military expedition planned by Home Riggs Popham and commanded by William Carr Beresford captured Buenos Aires and established a provisional government, which decreed free trade with Britain. The
Viceroy Rafael de Sobremonte had gone to Córdoba with the treasure and proclaimed that city as the provisional capital on 14 July 1806. On the other hand, in Montevideo, the French-born Spanish military man
Santiago de Liniers, who had been sent there by the viceroy, was organising an army to defeat the invasion. This army consisted of a cavalry unit commanded by
Juan Martín de Pueyrredón and composed of people from Buenos Aires and nearby towns. Besides, there were hundreds of volunteers. This army recovered Buenos Aires 46 days after it was captured; Beresford surrendered and was arrested. This event is known as
La Reconquista (The Reconquest). A few days after
La Reconquista, the Cabildo replaced Rafael de Sobremonte with Santiago de Liniers as viceroy, marking the first time a viceroy was selected by local authorities instead of the king. Between 1806 and 1807, Liniers organised urban militias in order to protect the Viceroyalty. Each militia was linked to a social class and a weapon. That was the beginning of important militias such as the
Regiment of Patricians, which would have an important role in the
May Revolution. On the other hand, the British never left the Río de la Plata, and kept up a blockade while waiting for reinforcements, which would arrive a year after the First Invasion. On 28 June 1807, the Second Invasion began under
John Whitelocke's command. This time, the British captured Montevideo first and defeated Liniers in the Battle of Cordón. In Buenos Aires,
Martín de Álzaga organised a resistance with urban militias and unarmed civilians. The British entered the city willing to capture the Fort (the government building), but were rejected by the people. The neighbors threw boiling water and other objects at the British soldiers. Finally, Whitelocke surrendered on 7 July. This event is known as
La Defensa (The Defence). The British invasions have many different interpretations according to each historiographical current. First, they are usually divided into the First and the Second Invasion, but some historians talk about a single invasion since the British never left the Río de la Plata. On the other hand,
Carlota Joaquina (sister of Ferdinand VII and spouse of the future King of Portugal) sent from Brazil a document called
Justa Reclamación (Fair Claim), in which she claimed having the right to govern the Spanish territories in America while her brother was kidnapped. That document started a political movement called Carlotism (
carlotismo in Spanish), composed of politicians like
Mariano Moreno and
Manuel Belgrano, who were looking for a greater participation of
criollo people in the Viceroyalty government. The
Justa Reclamación was rejected by Liniers and the Cabildo of Buenos Aires, and the project ended up failing due to lack of support. On 1 January 1809, the Peninsular merchant, Martín de Álzaga —who had organised
La Defensa during the Second British Invasion—
attempted to overthrow Liniers by demanding his resignation. He was supported by the Cabildo —which he presided over—, and many Peninsular urban militias, which were positioned all over the central square (
Plaza de la Victoria, nowadays known as
Plaza de Mayo). Liniers was about to sign his resignation and authorise the creation of a
junta, but then
Cornelio Saavedra appeared with his Regiment of Patricians and many civilians who supported Liniers, in order to prove that a majority of the population did so. After this, the attempted coup ended. He arrived in Montevideo first; De Elío recognised his authority and dissolved his
junta. Then Cisneros went to Buenos Aires, where Liniers gave him command peacefully. He indulted Martín de Álzaga and other persons involved in the attempted coup.
Revolutions in Chuquisaca and La Paz The capture of the Spanish kings —Charles IV and Ferdinand VII— by Napoleon created a
power vacuum that needed to be solved. In the Iberian Peninsula, the Spanish people refused to recognise the authority of Napoleon's brother as king and started to form
government juntas in the name of Ferdinand VII. The most important one was the
Supreme Central Junta, better known as the Junta of Sevilla, which was later dissolved after the
Battle of Ocaña, but replaced by the
Council of Regency of Spain and the Indies in 1810. Many political views lived together in the juntas, from liberals who were looking forward to democratising Spain, to conservatives who wanted to preserve the regime as it was before the French invasion. On the other hand, Napoleon didn't conquer Spanish America, but the authorities of those territories, such as the viceroys and the presidents of the
audiencias, had lost their superior —the King—, as well as their source of legitimacy. Because of this, many Spanish Americans wanted to imitate the Peninsular example and create their own government
juntas. On 25 May 1809, a
Revolution broke out in Chuquisaca, Upper Peru (present-day Bolivia), which was under the Viceroyalty of the Río de la Plata's jurisdiction. The judges (
oidores) of the Royal Audiencia of Charcas dismissed the president of the
audiencia and constituted the body as a government
junta, called Audiencia Gobernadora (Governing Audiencia). The reason behind this movement were the ideas of recognising either Carlota de Joaquina or Joseph Bonaparte as authorities, that were circulating around the capital of the Viceroyalty (carlotism and the Marquis of Sassenay sent by Napoleon). Nevertheless, there were politicians who were looking for a full independence of Upper Peru as well. In July 1809, the city of
La Paz (present-day administrative centre of Bolivia) followed Chuquisaca and
created its own junta, called Junta Tuitiva (Guardianship Board), but with a better marked goal for independence, as seen in its proclamation. The main figure of the Junta Tuitiva was
Pedro Domingo Murillo Though both La Paz and Chuquisaca were encompassed by the Viceroyalty of the Río de la Plata, the Viceroy Liniers didn't respond since its term was about to finish and his successor had already been appointed. Within that framework, the Viceroy of Peru,
José Fernando de Abascal y Sousa, acted quickly and sent
José Manuel de Goyeneche to suppress the Junta Tuitiva of La Paz, which was closer to the limits of Peru than Chuquisaca. The revolution was defeated and its main leaders, such as Murillo, were executed in January 1810. For his part, the new Viceroy of the Río de la Plata, Baltasar Hidalgo de Cisneros, appointed
Vicente Nieto as the new president of the Royal Audiencia of Charcas and launched an army under his command, composed by urban militias of Buenos Aires such as the
patricians and the arribeños. When this campaign arrived in Chuquisaca, the revolutionaries had already liberated the previous president of the
audiencia and cancelled the Audiencia Gobernadora, after seeing the disastrous ending of the La Paz revolution.
May Revolution On 18 May 1810, the news about the dissolution of Junta of Sevilla and its replacement by the Council of Regency arrived in Buenos Aires. This information made the legitimacy of the Viceroyalty government even more controversial. Not only was it not clear who the Viceroy should respond to in the absence of Ferdinand VII, but also whether the Viceroy was a legitimate authority, because the institution which had appointed him was not an official one created by the King, but by the Peninsular people, and no longer existed. Public opinion was divided between those who supported the continuity of Viceroy Cisneros, and those who wanted his replacement by a different government (the revolutionaries). This latter group was composed of many politicians from the Carlotism movement; since they wanted greater participation of the
criollo people in the government, as well as a modernisation of Spanish rule, they considered the situation as a great opportunity to found an American
government junta similar to the Peninsular ones. In this case, due to the crisis of legitimacy of Viceroy Cisneros, an Open Cabildo was capable of dismissing him. Therefore, on 21 May 1810,
Domingo French and
Antonio Luis Beruti, along with more than 600 people, occupied the Plaza de la Victoria —which would later be renamed as Plaza de Mayo, after these events— until the Viceroy accepted to convene one. The Open Cabildo took place on 22 May 1810 and voted 156 to 69 in favor of dismissing Cisneros. Finally, on 25 May 1810, the
Provisional Governing Junta of the Provinces of the Río de la Plata in the name of His Lord Don Ferdinand VII, commonly known as the Junta of Buenos Aires and historiographically as the Primera Junta (First Board) was created, with the leader of the Regiment of Patricians,
Cornelio Saavedra as chairman;
Juan José Castelli,
Manuel Belgrano,
Miguel de Azcuénaga,
Manuel Alberti,
Domingo Matheu and
Juan Larrea as members, and
Juan José Paso and
Mariano Moreno as secretaries. The Primera Junta swore loyalty to Ferdinand VII but refused to recognise the authority of the provisional government of the Iberian Peninsula (the Council of Regency) because it was not created by the King, was very conservative, and according to the retroversion of sovereignty, it should only govern the Peninsular people, since it was composed by them, having no authority over the rest of the Spanish Nation. The intentions behind the revolutionaries and the purpose of the May Revolution is
widely debated among the historians. The classic historiographical current, headed by the 6th President of Argentina,
Bartolomé Mitre, states that some of the revolutionaries wanted independence from the very beginning, but they had to hide their intentions until the international situation was favorable. This strategy, called the Mask of Ferdinand VII, implied swearing loyalty to him. Other historians say that independence was not the goal at first; instead, the revolutionaries, influenced by liberal ideas, would have wanted to modernise and democratise the Spanish government, just as the liberals of the Peninsular
juntas. When the provisional Spanish governments and later the restored reign of Ferdinand VII turned conservative, independence ended up being the only option. The Spanish administrative divisions that confronted the United Provinces during the
Argentine War of Independence were both conservative and anti-independence, so those conflicts are explained by the two main interpretations of the Revolution.
Downfall The May Revolution marked the beginning of the
United Provinces of the Río de la Plata and ended the viceregal system in Buenos Aires at first. One of the first measures of the new Junta was to announce its foundation to the cities and ask them to send representatives. Nonetheless, not every province of the Viceroyalty came under the authority of the new state. The intendancies of Upper Peru (Chuquisaca, La Paz, Potosí, Cochabamba), along with its political-military governments (Moxos and Chiquitos) were annexed by the Viceroyalty of Peru as an emergency measure to stop the spread of the revolution; the same happened with the Intendancies of Salta del Tucumán and Córdoba del Tucumán, though they would be recovered by the United Provinces later, unlike Upper Peru, which ended up being a different country (
Bolivia). The Intendancy of Paraguay, for its part, swore loyalty to the Council of Regency and refused to recognise the authority of the Junta of Buenos Aires, defeating it during the
Paraguay campaign. However, the Guaraní nation declared independence and signed a peace treaty with the Provinces of the Río de la plata a year later. The territory of the Banda Oriental (present-day Uruguay) that depended directly on the Intendancy of Buenos Aires received the circular sent by the Junta very quickly. Nevertheless, the Political and Military Government of Montevideo rejected the authority of the Primera Junta. Just as Buenos Aires did not recognise the legitimacy of the Council of Regency, this institution did not recognise the authority of the Junta of Buenos Aires. That is why the Regency appointed
Gaspar de Vigodet as governor of Montevideo and Francisco Javier de Elío as new Viceroy of the Río de la Plata in August-September 1810. Vigodet's government achieved important victories against the Junta, such as the
Battle of San Nicolás, taking over the majority of the Banda Oriental and securing the naval superiority of Montevideo and its control over the rivers. Elio, for his part, arrived in Montevideo later and demanded the Junta to recognise his authority as Viceroy. He was rejected, so he declared Buenos Aires a rebel city and proclaimed Montevideo as the new capital of the Viceroyalty. Thus, the Viceroyalty of the Río de la Plata continued existing in Montevideo and other cities that were temporarily controlled by that government for a few more years. Elío exercised his power in Montevideo, but he was not widely accepted as Viceroy in the countryside of the Banda Oriental. On 28 February 1811, the
Cry of Asencio took place; Commander Pedro José Viera, along with some gauchos and ranchers, started a rebellion against Elío's regime, which was supported by the Provinces of the Río de la Plata. When the Paraguay campaign was finished, the Junta of Buenos Aires ordered Belgrano to march towards the Banda Oriental. He contacted
José Gervasio Artigas, who had deserted from an army under Elío's command and made himself available to the Junta, and was leading the popular uprising against Montevideo authorities. Under his command, important victories were achieved, like the
Battle of Las Piedras, which left the Viceroy with only Montevideo and Colonia del Sacramento.
Both territories were besieged by the Provinces of the Río de la Plata, and Colonia del Sacramento was abandoned by the authorities of Elío. As a last resort, the Viceroy asked the Portuguese of Brazil to attack the Banda Oriental. This sudden invasion, along with the defeat in the
Battle of Huaqui, made the Provinces of the Río de la Plata —at that time, led by the
First Triumvirate, which had replaced the Junta— sign a treaty with Montevideo on 21 October 1811. This agreement, called
Tratado de Pacificación (Treaty of Pacification) ended the siege, accepted the authority of Viceroy Elío over the Banda Oriental and reaffirmed the recognition of Ferdinand VII as king by both parties. This treaty was not well received by the Council of Regency, which ordered Elío to return to the Peninsula and replaced him with Gaspar de Vigodet, with the rank of General Captain of the Río de la Plata, turning the Viceroyalty of the Río de la Plata into something similar to a
general captaincy. The agreement did not last long, as Artigas refused to accept it and the United Provinces did nothing to stop him. On 20 October 1812, the United Provinces
reestablished the siege of Montevideo. Within that framework, the urban militias of the city started to attack and sack the coasts of the
Uruguay and
Paraná Rivers to obtain food supplies, but this stopped after the victory of the United Provinces against them in the
Battle of San Lorenzo, under
José de San Martín's command. Even so, by 1813 Montevideo had not fallen, so the government of Buenos Aires changed its strategy. Between 1813 and 1814, a small fleet was created with the mission of disputing the Montevidean control of the rivers; the Irishman
Guillermo Brown was selected as commander. On 15 March 1814, the fleet defeated Captain Jacinto Romarate in the Naval
Battle of Martín García, and occupied the
strategic island. After this, on 20 April 1814, Brown established a naval blockade against Montevideo, and defeated its navy again in the
Battle of Buceo; this ended the naval superiority of Montevideo. On 17 May 1814, Vigodet negotiated the surrender. Finally, on 23 May 1814,
Carlos María de Alvear, who was in charge of the ground troops, took over the city, marking the
de facto ending of the Viceroyalty of the Río de la Plata.
Formal abolition After 1814, the Viceroyalty of the Río de la Plata existed only on paper. On 27 May 1825, after learning about the defeat of the Spanish army in the
Battle of Ayacucho, Ferdinand VII designated
Pedro Antonio Olañeta, a very loyal
royalist commander, as viceroy of the Río de la Plata. This appointment was primarily symbolic, since the Viceroyalty had been liberated more than a decade earlier. However, Olañeta had died on 1 April 1825 during the
Battle of Tumusla, but the news had not yet reached Spain. Logically, he could not exercise his office. In the second half of the 19th century, Spain recognised the independence of the new countries that were part of the Viceroyalty on the following dates: • Argentina (United Provinces): 27 June 1860 • Bolivia (Upper Peru): 12 February 1861 • Paraguay: 8 April 1882 • Uruguay (Banda Oriental): 9 October 1882. ==Economy and society==
