The territory of modern Guatemala once formed the core of the Maya civilization, which extended across Mesoamerica. Most of the country was conquered by the Spanish in the 16th century, becoming part of the viceroyalty of New Spain. Guatemala attained independence in 1821 as part of the Federal Republic of Central America, which dissolved in 1841. 

From the mid to late 19th century, Guatemala experienced chronic instability and civil strife. Beginning in the early 20th century, it was ruled by a series of dictators backed by the United Fruit Company and the United States government. In 1944, authoritarian leader Jorge Ubico was overthrown by a pro-democratic military coup, initiating a decade-long revolution that led to sweeping social and economic reforms. A U.S.-backed military coup in 1954 ended the revolution and installed a dictatorship.
