Prehistory Before the arrival of Portuguese settlers, in the
16th century (the first reports give account of expeditions that went up the
Jequitinhonha and
São Francisco Rivers), Diamantina, like the entire region of the current state of Minas Gerais, was occupied by
indigenous peoples of the
Macro-Jê languages.
Foundation and exploration of diamonds Diamantina was founded as Arraial do Tejuco in 1713, with the construction of a chapel that honored the patron
Saint Anthony of Padua. The locality had strong growth when the Diamonds were discovered in 1729. At the end of the 18th century, it was the third largest population in the Captaincy General of Minas, behind the capital Vila Rica, today
Ouro Preto, and with a population similar to that of the prosperous
São João del-Rei. In the 18th century it grew due to the large local production of diamonds, which were exploited by the Portuguese crown. In 1697, the Estrada Real was established by the crown to promote development of the interior, reaching from the coast through Ouro Preto onwards to Diamantina. The town was initially known as Arraial do Tejuco (or Tijuco) (from the
Tupi tyîuka, "rotten water"), Tejuco and Ybyty'ro'y (Tupi word meaning "cold mountain", by the junction of ybytyra ("mountain").) and ro'y ("cold"). During the 18th century, the city was famous for having sheltered
Chica da Silva, a freed slave who was the wife of the richest man in
Colonial Brazil, João Fernandes de Oliveira. Diamantina represented the largest mining of diamonds in the western world in the 18th century, and for nine years, the
Portuguese Crown was not aware of the discovery of diamonds in the region, which was done by the governor of the
Captaincy, in 1729, the then D. Lourenço de Almeida. Portugal's response was to impose full control over the diamond regions of Minas Gerais. In 1734, the Intendency of Diamonds was created, whose regime was totally controlling and authoritarian. The Portuguese Crown's monopoly over diamond deposits lasted until 1845.
Incorporation, transformation into historical heritage and recent history Diamantina emancipated itself from the municipality of
Serro only in 1831, changing its name to Diamantina because of the large volume of diamonds found in the region. The delay was due to the need for greater local control by the colonial authorities, since in the mid-18th century the population was larger than that of Vila do Príncipe do Serro Frio, head of the region. Life in Diamantina at the end of the 19th century was portrayed by
Alice Brant in her book
Minha Vida de Menina, which became a landmark in Brazilian literature after being rediscovered by
Elizabeth Bishop.In 1938, Diamantina celebrated its 100th anniversary as a city, receiving the title of "National Historic Heritage" from the
National Institute of Historic and Artistic Heritage. With the arrival of
Juscelino Kubitschek to the state government and later to the
Presidency of the Republic, many improvements were made in Diamantina, such as the foundation of the Federal School of Dentistry of Diamantina, the Hotel Tijuco, the Júlia Kubitschek State School and the Diamantina Sports Square. In 1999, it was elevated to the category of "heritage of humanity" by the
United Nations Educational, Scientific and Cultural Organization. == Geography ==
