Leonello d'Este

Leonello was one of three illegitimate sons of Niccolò d'Este III and Stella de' Tolomei. He received a military education under the condottiero Braccio da Montone, and was tutored by Guarino Veronese, later appointed professor at the University of Ferrara, who also instructed him on the traits of a desirable ruler and how to govern. In 1425, after the execution of his elder brother Ugo Aldobrandino, he was the sole heir of Niccolò. In 1435, he married Margherita Gonzaga on 6 February and was recognized as legitimate son by Pope Martin V. Margherita, who died in 1439, gave birth to a child, Niccolò, in 1438, who is also known as Niccolò di Leonello to avoid confusion with his grandfather Niccolò d'Este III. Niccolò the son died in 1476. In late December 1441, Leonello succeeded to his father's possessions after his death in northern Italy. Coming from a strong academic background, Leonello brought significant unprecedented economic, political, and cultural changes to Ferrara right after he took over from Niccolò III. In May 1444, Leonello married Mary of Aragon who was at the age of 19, an illegitimate daughter of King Alfonso V of Naples. The marriage was a political one. To ensure the political stability within Ferrara, Leonello remained neutral in the political affairs between Milan and Venice. However, Leonello had a much broader picture for Ferrara, expanding its authority and power in its area. After the death of Margherita Gonzaga, Leonello saw the opportunity of forming alliances with neighboring regions through kinship to strengthen its power. The victory of Alfonso V in Naples, the father of Mary of Aragon, acted as a catalyst for such a diplomatic marriage for Leonello and an opportunity for Ferrara. Not much progress was made during the rule of Niccolò III as he focused more on political matters and economic prosperity within Ferrara. Leonello was a skilled politician and was responsible for the construction of the first hospital of Ferrara. But he distinguished himself chiefly as a man of culture. Leon Battista Alberti wrote his De Re Aedificatoria at Leonello's commission, and at the Ferrarese court there worked artists such as Pisanello, Iacopo Bellini, Giovanni da Oriolo, Andrea Mantegna, Piero della Francesca and the Netherlandish Rogier van der Weyden. His personal breviary was sold in a fragmented state in 1958 by Baron Llangattock at Christie's. It has since then been known as the Llangattock breviary. It was created under the artistic direction of Giorgio d´Alemagna and painters like Matteo De Pasti and Jacopo Magnanimo contributed to it. Leaves from it are in the collections of museums such as the Louvre in Paris, the Danish National Library, and several private collections. During his rule, the University of Ferrara gained a European prestige. Leonello died in 1450, aged 43. He was succeeded by Borso d'Este, his father's illegitimate son. ==Family background and history==

Parents and succession Leonello d’Este's father, Niccoló d’Este III, was also an illegitimate son himself. At the age of nine, Niccoló became legitimated as the successor of Leonello's grandfather, Alberto. However, Leonello's circumstances for securing his rights to succession differed from his father's, primarily because Niccoló was Alberto's only son while Leonello was in a competition with his younger legitimate brothers. In the presence of his legitimate sons from his later marriage, Niccoló needed to prove that Leonello was qualified to be chosen as his successor. Niccoló defended Leonello's rights to succession on three grounds: Leonello's personal attributes, popularity among his subjects, and official papal recognition. Leonello was often praised for exhibiting strong leadership skills and virtuous characteristics, which would make him a worthy heir and future ruler of Ferrara. His father noted that this high level of education further distinguished Leonello from his siblings. Leonello was also popular among the people and his father recognized the wide support that Leonello would receive from his subjects, who approved of Leonello being chosen as Niccoló's successor. Thus, by 1434, Leonello was given a great deal of authority to co-rule with his father. Leonello's succession and subsequent marriage would also serve an important role in relations with neighbouring city-states. Previously, the House of Este owed a great debt to Gianfrancesco Gonzaga, the ruler of Mantua. This also reflects the gender attitudes regarding the political successions in the House of Este during this time period. A greater preference was given for illegitimate sons to become successors, instead of legitimate daughters. Leonello himself was also succeeded by a man who had an illegitimate birth status. His brother, Borso, who was born from the same mother of Leonello, was later chosen to be Leonello's successor. ==Culture, art and literature==

Culture University The University of Ferrara dates back to 1391. It was not until 1442—one year into the reign of Leonello d’Este—that it became a fully operational university with an adequate number of professors to instruct the major subjects of canon law (church law), logic, philosophy and medicine. A meeting in January 1442 between Leonello and the commune, resulted in the agreement for the need for a university, saying it would be "a distinguished center of learning [that] would bring renown to the city, local men would more easily obtain degrees, and an influx of students would bolster the city’s economy." In order to raise funds, the commune placed a sales tax on meats and through the money raised was able to pay a large portion of the faculty for the university; Leonello contributed financially in order to keep the university afloat. Leonello's education of the new principles in the studia humanitatais Decembrio's connection to Leonello comes from his work he wrote before 1447, the De Politia Litteraria Variisque Poetae Virgilli Laudbibus, which was a dialogue divided into three volumes; four more books were added around 1462. The treatise was about how to successfully sustain the refinement of literature/politia litteraria in a courtly environment. He would perform his music on a lute. Pietrobono's first appearance was in the early court of Leonello d' Este of 1441. by Leonello which was the sum that was apparently the common payment that the Este family had use in the past, with such people as Dufay in 1437. Leonello's interest in Roman Antiquity had to do with his education and exposure to humanism under the instruction of his tutor Angelo Decembrio. The medals from 1441, 1444 and 1450 all demonstrate the characteristics of Leonello and/or his court. Each coin has on one side a portrait of Leonello in Roman emperor portraiture style, and has on the other side an image that represents Leonello and his court. The design with the lion and angels represented aspects of the Este family history, specifically with association to Leonello and his court. This coin is also in the Victoria and Albert Museum. Stahl also mentions that the replication process was developed about a century after Leonello's death, so even though Pisanello's coins were for Leonello – according to Alan – it was the beginning of the development for replication within Ferrara, which would develop in the following centuries. Leonello d’Este employed him in 1447, and Giovanni's only identified picture is his portrait of Leonello. The book detailed the concerns regarding materials, construction, overall principles and foundation of the overall design, and the ideas behind public and private buildings. It also spoke about the different types of building façades and discussed ways to fix construction errors. In 1441, Leonello invited Alberti to judge a competition to find an artist to create a sculpture of his father. Through his influence as Marquis and the family name of Este, Leonello was able to develop the De Re Aedificatoria under his reign. ==Political influence==

Unlike his politically driven father, Nicolo III, Leonello d’Este (1407 to 1450), exerted significant influence over the Italian political landscape and aristocracy by being a man of culture and giving support to the arts. Leonello's legacy would remain that of a man of culture, with other members of the d’Este family pursuing political leadership such as Nicollo III, Ercole I and Isabella d’Este. Ferrara political background The House of Este, a princely family of Lombardy ruling in Ferrara between the 13th and 16th centuries, contributed a great deal to Italy during this period. The Estense dynasty gained the Ferrara territory in 1240 in addition to their other lands. Over various periods of time, however, a considerable amount of their territory was lost to French papal and imperial forces. Dukes in Ferrara were elected through a formal voting process by the citizens. When appointed they were given a hereditary title. After the marriage of Azzo V to the heiress of a rival family and the successor of Obizzo I, grandson Azzo VII, bringing political prominence to Ferrara. By 1240, Azzo VII had control of Ferrara (in alliance with Pope Gregory IX), which marked the start of the Este rule. The Estense government was faced with papal opposition from the onset, however, by the start of the 14th century had recovered its political influence and strength under Nicolo II. His successor, Nicolo III is remembered for having further strengthened power in Ferrara and introducing the Estense political influence to Italy. Succeeding a Paduan attempt to gain authority in Ferrara, Nicolo III was commended as go-between in the political and military disputes in the Italian states, extending Ferrara's territory and domain. Leonello's education by humanist Guarino Veronese directed his interest towards the humanism and art. Leonello was chosen to be the heir of the d’Este patrimony through papal sanction, by his father at the age of 21. After the passing of his first wife, Margherita Gonzana, Leonello married Maria d’Aragona, an illegitimate daughter of the King of Naples. Leonello's leadership did result in some minor improvements to the local economy in Ferrara, however, his major influence remained in the cultural sphere. Leonello's governing also brought improvements to the court library, commissioning copyists to produce manuscripts in both French and Italian. The construction of a Chapel during Leonello's governing is demonstrative of this new concentration of the domestic domain of the Este court. Over time Leonello's rule in Ferrara has been defined by his cultural contributions. Political influence following Leonello Leonello's rule was followed in Ferrara by his half-brother Ercole I, who garnered substantial political support. Succeeding Ercole I was another significant political player in the House of Este, Isabella d’Este, whom married Francesco Gonzaga in 1490. Isabella is remembered for her determination and unusual aptitude for a forward-thinking "political strategy". Isabella's fascination and involvement with political strategy and intelligence sparked the literary trend by women in 15th century Italy, being an influential aspect of the new "literary discourse" about women that occurred in the northern courts of Italy. Isabella was an advocate for female education, as she believed that it would construct masculine characteristics of practicality and strength, which are fundamental aspects of asserting political authority. The house of Este had many politically driven leaders in power, however Leonello d’Este remains primarily known and acknowledged for his involvement with humanism, the arts and culture. ==Death, legacy and successor==

On 1 October 1450, Leonello suddenly died of unknown causes. Borso d'Este, his brother, succeeded the throne of Marquis of Ferrara. In stark contrast to his brother, Borso received little education and was more interested in political affairs. During the reign of Borso, the legacy of art and literature proceeded with a rather stagnant growth as they were mostly used for military propaganda and entertainment. Aside from cultural developments, however, Borso utilized the foundation laid down by his brother, Leonello, to assist him in reforming the structure and organization of the state. In particular, the diplomatic relationship previously built up by Leonello served as a basis for Borso to further leverage its alliance with other cities. The impact of Leonello, however, was much greater and lasted much longer than the reign of Borso. The ties between the Kingdom of Naples and Ferrara carried on to the realm of Ercole, who succeeded Borso d’Este as Duke of Ferrara. Ercole married with Eleonora d’Aragona, Maria's niece, under the same contract Leonello signed in 1444 with Naples. ==References==
