Manaus
Early settlement of Manaus

The history of the European colonization of Manaus began in 1499 with the Spanish arrival at the mouth of the Amazon River. The Spanish then continued to colonize the region north of Brazil. Development continued in 1668–1669 with the building of the Fort of São José da Barra do Rio Negro by the Portuguese in order to ensure its predominance in the region, especially against the Dutch, at that time headquartered in what is today Suriname. The fort was constructed in rock and clay, with four cannons guarding the curtains. It continued to function for more than 100 years. Next to the fort there were many indigenous mestizos, who helped in its construction and began to live in the vicinity.

The population grew so much that, in 1695, the missionaries (Carmelite, Jesuit, Franciscan) built a nearby chapel dedicated to Nossa Senhora da Conceição (Our Lady of the Conception), who, in time, became the patron saint of the city. A Royal Charter of March 3, 1755 created the captaincy of São José do Rio Negro, with capital in Mariuá (now Barcelos), but with the governor, Lobo D'Almada, fearing a Spanish invasion, the seat went back to Lugar de Barra in 1791. Being located at the confluence of the Rio Negro and Amazon Rivers, it was a strategic point. On November 13, 1832, Lugar da Barra was elevated to town status and named Manaus. On October 24, 1848, under Law 145 of the Provincial Assembly of Para, it was renamed the City of Barra do Rio Negro. On September 4, 1856, the governor, Herculano Ferreira Pena, finally gave it the name "Manaus".
