Hayti, Haiti, St. Domingo, or Hispaniola. The largest island in the West Indies, with the exception of Cuba. It was discovered by Christopher Columbus in 1495. Until 1665 Spain kept possession of the island; but in that year the French obtained a footing, and retained their position for upwards of a century and a quarter. In 1800 the independence of Hayti was proclaimed by the negro population, and the French finally quitted the island in 1803. Since that time various revolutions have occurred, and a kind of military elective government has prevailed under different leaders. In 1849 the former French portion of the island was proclaimed an empire under its president, Solouque, who took the title of Faustin I. The sable emperor was, however, deposed in 1858, and a republic was again proclaimed.
