English and Irish colonists from St. Kitts first settled on Montserrat in 1632; the first African slaves arrived three decades later. The British and French fought for possession of the island for most of the 18th century, but it finally was confirmed as a British possession in 1783. The island's sugar plantation economy was converted to small farm landholdings in the mid-19th century. The Soufriere Hills Volcano erupted in 1995, devastating much of the island; two thirds of the population fled abroad. Montserrat has endured volcanic activity since, with the last eruption occurring in 2013.
