History of Sao Luis

date of the founding of the city, whether by the French or the Portuguese. In 1641, the city was invaded by the Dutch. They stayed until 1645 and did not manage to influence the city's architecture or to leave any sign of their invasion, mainly because they were kept too busy with the challenges to their occupation. In 1677, the city was made the seat of the new Roman Catholic Diocese of São Luís do Maranhão.

Only when those invasions ceased permanently did the colonial government decide to create the state of Grão-Pará e Maranhão, independent from the rest of the country. By that time, the economy was based on agriculture, particularly the exportation of sugar cane, cacao and tobacco. Conflicts amongst the local elites would lead to the Beckman's Revolt.

Soon after the outbreak of the American Civil War, the region started to provide cotton to Great Britain. The wealth generated by this activity was used to modernize the city; to bring religious men to come and teach in its schools; and supplement the water supply. The city came to be the third most populous city in the country. By the end of the 19th century, agriculture was in decay and since then the city's population has been searching for other ways to make a living.

Nowadays, São Luís has the largest and best preserved heritage of colonial Portuguese architecture of all Latin America. The island is known as the "Island of Love" and as "the Brazilian Athens", due to its many poets and writers, such as Sotero dos Reis, Aluísio Azevedo, Graça Aranha, Gonçalves Dias (the most famous), Josué Montello, Ferreira Gullar, among others.

The ancestral composition of São Luís, according to an autosomal DNA study, is 42% European, 39% Native American and 19% African.
