The smallest and most densely populated Central American country, it is crossed by two volcanic mountain ranges and has a narrow coastal region and a high central plain in the south. The climate ranges from hot and wet in the lowlands to cooler and wetter in the highlands. Cloud forests predominate at the highest elevations. El Salvador has a developing economy based on services, trade, manufacturing, and agriculture, with coffee, sugarcane, and cotton as the major export crops. Remittances from Salvadorans living in the U.S. are, collectively, among the country's largest sources of income. El Salvador is a republic with one legislative house; its head of state and government is the president. The Spanish arrived in the area in 1524 and subjugated the Pipil Indian kingdom of Cuzcatlán by 1539. The country was divided into two districts, San Salvador and Sonsonate, both attached to Guatemala. When Spanish rule ended in 1821, the Salvadorans opposed incorporation into the Mexican Empire (confronting both Guatemalan and Mexican armies), and, upon its collapse in 1823, Sonsonate and San Salvador combined to form the new state of El Salvador within the United Provinces of Central America. The country attained independence in 1841. From its founding, it experienced a high degree of political turmoil; powerful economic interests controlled the country through most of the 19th and early 20th centuries but were replaced by a military dictatorship that lasted from 1931 to 1979. Elections held in 1982 set up a new government, and, though a new constitution was adopted in 1983, civil war continued throughout the 1980s. Peace accords in 1992 ended the war, but violent crime became a major problem. Despite attempts at economic reform, the country was plagued by inflation and unemployment into the 21st century. In 2006 El Salvador officially entered into the Central American Free Trade Agreement (CAFTA) with the United States.
