Haiti

Haiti is located on the western third of the island of Hispaniola and shares the island with the Dominican Republic. Haiti has a total area of 10,700 square miles and a population of over 5 million. The capital of Haiti is Port-au-Prince. 

The island of Hispaniola was originally settled by the Arawak Amerindians. After Columbus landed on the island in 1492 and claimed it for Spain; the Spanish began systematically exterminating the Arawaks there and on other islands in the Caribbean. Spain ceded the western third of the island to France in 1697. During the French Colonial period, Haiti became one of the wealthiest colonies in the Caribbean; it's economy driven by sugar cane and slaves. In 1791, Toussaint L'Ouverture led a revolt of over half a million slaves and in 1804, Haiti became the western hemisphere's first Black Republic. 

During most of the twentieth century, the Duvalier family; "Papa Doc and Baby Doc" ruled Haiti under a brutal dictatorship. The government of Jean Claude "Baby Doc" Duvalier was overthrown in 1986 and since that time, Haiti has seen several repressive governments come and go. The United States has intervened in the country twice since 1986. Today, Haiti is the poorest country in the Western Hemisphere.
