Manaus

Manaus began as a small fort, São José da Barra, created in 1669 by Portuguese settlers as a defense against Spanish incursions into Brazil by way of the Amazon River. On November 13, 1832, the settlement gained the status of Vila, and was named "Manaus", after the indigenous tribe, the "Manaós", which once inhabitated the area. In the local language, the word means "Mother of God". On October 24, 1848, Manaus was awarded the status of city with the name Cidade da Barra do Rio Negro. In 1850, Amazonas became a province. On September 4, 1856, the city was renamed Cidade de Manaus.

From 1890 to 1920, Manaus was a rubber boomtown, which was caused in part by the invention of the process of vulcanization. The plantantion owners became extravagantly wealthy and the city prospered. Immigrants from northeastern Brazil, fleeing drought and poverty, flooded the city seeking riches in the rubber trade. By 1920, synthetic rubber and the growth of plantations in Southeast Asia caused a drastic plunge in the price of rubber, and Manaus declined into poverty.
