Slavery was abolished in Brazil on this date in 1888.

Slavery was legally ended nationwide on May 13 by the Lei Aurea ("Golden Law") of 1888, by a legal act of Isabel, Princess Imperial of Brazil. In fact, it was an institution in decline by this time. (Since the 1880s the country began to attract European immigrant labor instead). Brazil was the last nation in the Western Hemisphere to abolish slavery. source
