Political map of South American nations 4 March 1887 (Counani Dispute): When gold was discovered in the Guianas in the early 1880s, thousands of prospectors flocked to the region. Taking advantage of Brazil's continued use of slaves (Slavery in Brazil), the French provoked a revolt in the disputed area bordering French Guiana, promoting the short-lived Republic of Counani. However, the republic was disbanded after Brazilian protests, and, once Brazil finally abolished slavery in 1888 (Lei Aurea), both local and international opinion shifted decisively in favor of Brazilian governance of the territory.
