Haiti is a founding member of the United Nations, Organization of American States (OAS), Association of Caribbean States, and the International Francophonie Organisation. In addition to CARICOM, it is a member of the International Monetary Fund, World Trade Organization, and the Community of Latin American and Caribbean States. Historically poor and politically unstable, Haiti has the lowest Human Development Index in the Americas. Since the turn of the 21st century, the country has endured a ''coup d'état,'' which prompted a U.N. intervention, as well as a catastrophic earthquake that killed over 250,000 people.
