President of Guatemala in the context of Jacobo Arbenz Guzmán

Jorge Ubico Castañeda (10 November 1878 – 14 June 1946), nicknamed Number Five or also Central America's Napoleon, was a Guatemalan military officer, politician, and dictator who served as the president of Guatemala from 1931 to 1944.

A general in the Guatemalan military, he was elected to the presidency in 1931, in an election where he was the only candidate. He continued his predecessors' policies of giving massive concessions to the United Fruit Company and wealthy landowners, as well as supporting their harsh labor practices. Ubico has been described as "one of the most oppressive tyrants Guatemala has ever known" who compared himself to Adolf Hitler. He was removed by a pro-democracy uprising in 1944, which led to the ten-year Guatemalan Revolution.

The Republic of Guatemala is divided into 22 departments (Spanish: departamentos)which in turn are divided into 340 municipalities. The departments are governed by a departmental governor, appointed by the President.

In addition, Guatemala has claimed that all or part of the nation of Belize is a department of Guatemala, and this claim is sometimes reflected in maps of the region. Guatemala formally recognized Belize in 1991, but the border disputes between the two nations have not been resolved.

The Guatemalan Armed Forces (Spanish: Fuerzas Armadas de Guatemala) is the unified military organization comprising the Guatemalan Army, Navy, Air Force, and Presidential Honor Guard. The president of Guatemala is the commander-in-chief of the military, and formulates policy, training, and budget through the Minister of Defence. Day-to-day operations are conducted by the Chief of the General Staff.

Juan Jacobo Árbenz Guzmán (Spanish: [xwaŋ xaˈkoβo ˈaɾβens ɣusˈman]; 14 September 1913 – 27 January 1971) was a Guatemalan military officer and politician who served as the 25th president of Guatemala. He was Minister of National Defense from 1944 to 1950, before he became the second democratically elected President of Guatemala, from 1951 to 1954. He was a major figure in the ten-year Guatemalan Revolution, which represented some of the few years of representative democracy in Guatemalan history. The landmark program of agrarian reform Árbenz enacted as president was very influential across Latin America.

Árbenz was born in 1913 to a wealthy family, son of a Swiss German father and a Guatemalan mother. He graduated with high honors from a military academy in 1935, and served in the army until 1944, quickly rising through the ranks. During this period, he witnessed the violent repression of agrarian laborers by the United States-backed dictator Jorge Ubico, and was personally required to escort chain-gangs of prisoners, an experience that contributed to his progressive views. In 1938, he met and married María Vilanova, who was a great ideological influence on him, as was José Manuel Fortuny, a Guatemalan communist. In October 1944, several civilian groups and progressive military factions led by Árbenz and Francisco Arana rebelled against Ubico's repressive policies. In the elections that followed, Juan José Arévalo was elected president, and began a highly popular program of social reform. Árbenz was appointed Minister of Defense, and played a crucial role in putting down a military coup in 1949.

Manuel José Estrada Cabrera (21 November 1857 – 24 September 1924) was the President of Guatemala from 1898 to 1920. A lawyer with no military background, he modernised the country's industry and transportation infrastructure, via granting concessions to the American-owned United Fruit Company, whose influence on the government was deeply unpopular among the population. Estrada Cabrera ruled as a dictator who used increasingly brutal methods to assert his authority, including armed strike-breaking, and he effectively controlled general elections. He retained power for 22 years through controlled elections in 1904, 1910, and 1916, and was eventually removed from office when the national assembly declared him mentally incompetent, and he was jailed for corruption. As such, he was the longest-serving leader of Guatemala.

Carlos Castillo Armas (locally ['kaɾlos kas'tiʝo 'aɾmas]; 4 November 1914 – 26 July 1957) was a Guatemalan military officer and politician who was the 28th president of Guatemala, serving from 1954 to 1957 after taking power in a coup d'état. A member of the far-right National Liberation Movement (MLN) party, his authoritarian government was closely allied with the United States.

Born to a planter, out of wedlock, Castillo Armas was educated at Guatemala's military academy. A protégé of Colonel Francisco Javier Arana, he joined Arana's forces during the 1944 uprising against President Federico Ponce Vaides. This began the Guatemalan Revolution and the introduction of representative democracy to the country. Castillo Armas joined the General Staff and became director of the military academy. Arana and Castillo Armas opposed the newly elected government of Juan José Arévalo; after Arana's failed 1949 coup, Castillo Armas went into exile in Honduras. Seeking support for another revolt, he came to the attention of the US Central Intelligence Agency (CIA). In 1950 he launched a failed assault on Guatemala City, before escaping back to Honduras. Influenced by lobbying by the United Fruit Company and Cold War fears of communism, in 1952 the US government of President Harry Truman authorized Operation PBFortune, a plot to overthrow Arévalo's successor, President Jacobo Árbenz. Castillo Armas was to lead the coup, but the plan was abandoned before being revived in a new form by US President Dwight D. Eisenhower in 1953.

Juan José Arévalo Bermejo (10 September 1904 – 8 October 1990) was a Guatemalan statesman and professor of philosophy who became Guatemala's first democratically elected president in 1945. He was elected following a popular uprising against the United States-backed dictator Jorge Ubico that began the Guatemalan Revolution. He remained in office until 1951, surviving 25 coup attempts. He did not contest the election of 1951, instead choosing to hand over power to Jacobo Árbenz. As president, he enacted several social reform policies, including an increase in the minimum wage and a series of literacy programs. He also oversaw the drafting of a new constitution in 1945. His son, Bernardo, became President of Guatemala in 2024.

Because of his reforms and policies that transcended his time, Juan José Arévalo is considered the most popular and influential president in the history of Guatemala.

Politics of Guatemala takes place in a framework of a presidential representative democratic republic, where by the President of Guatemala is both head of state, head of government, and of a multi-party system. Executive power is exercised by the government. Legislative power is vested in both the government and the Congress of the Republic. The judiciary is independent of the executive and the legislature. Guatemala is a Constitutional Republic.

Guatemala's 1985 Constitution provides for a separation of powers among the executive, legislative, and judicial branches of government.
