They had lived in Guatemala, Honduras, Belize, the southern part of Mexico and eastern parts of El Salvador. After independence from Spain in 1821, Guatemala was a part of the Federal Republic of Central America and after its dissolution the country suffered much of the political instability that characterized the region during mid to late 19th century. Early in the 20th century, Guatemala had a mixture of democratic governments as well as a series of dictators, the last of which were frequently assisted by the United Fruit Company and the United States government. From 1960 to 1996, Guatemala underwent a civil war fought between the government and leftist rebels. Following the war, Guatemala has witnessed both economic growth and successful democratic elections. In the most recent election, held in 2011, Otto Pérez Molina of the Patriotic Party won the presidency.Guatemala's abundance of biologically significant and unique ecosystems contributes to Mesoamerica's designation as a biodiversity hotspot.
