Brazil's 1877–78 Grande Seca (Great Drought) in the cotton-growing northeast led to major turmoil, starvation, poverty and internal migration. As wealthy plantation holders rushed to sell their slaves south, popular resistance and resentment grew, inspiring numerous emancipation societies. They succeeded in banning slavery altogether in the province of Ceará by 1884. Slavery was legally ended nationwide on 13 May by the "Lei Áurea" ("Golden Law") of 1888. It was an institution in decadence at these times, as since the 1880s the country had begun to use European immigrant labor instead. Brazil was the last nation in the Western Hemisphere to abolish slavery. The Republic of Ragusa became the first European country to ban the slave trade in 1416. In modern times Denmark-Norway abolished the trade in 1802.
