Following the Spanish–American War, military operations on the North American continent were largely confined to American occupations,
police actions, and interventions in Central America and the Caribbean. These military interventions, collectively referred to as the
Banana Wars, were conducted to maintain American economic interests in the area. The series of conflicts ended in 1934, with their
withdrawal from Haiti, and the adoption of
Good Neighbor policy by American President
Franklin Roosevelt. During the early-20th century, the two intermittent indigenous conflicts that began in the 16th century came to an end. The last skirmish of the American Indian Wars was in 1924, when the
last Apache raid in the United States took place. The last skirmish of the Mexican Indian War was in 1933, between the Mexican government, and the
Maya people of the Yucatán. The first half of the 20th century saw two significant civil conflicts in Mexico. The Mexican Revolution, from 1910 to 1919, saw a series of successive political rebellions against the government of Mexico. The conflict resulted in the creation of the
1917 Constitution of Mexico. The
Cristero War, from 1926 to 1929, was a widespread rebellion against the
secularist, anti-Catholic and
anti-clerical policies of the incumbent Mexican government. The conflict came to an end following an American-brokered ceasefire in 1929. During
World War II, the
North American theatre was a minor area of the conflict, although several isolated attacks on the North American coast were carried out by the
Empire of Japan, and
Nazi Germany. From 1942 to 1943, American and Canadian forces were engaged in the
Aleutian Islands Campaign, where they defended the
Alaska Territory against Japanese incursion. On the eastern side of the continent, the
Battle of the St. Lawrence was an anti-submarine campaign between Canada and Germany. The Battle of the St. Lawrence is considered to be a part of the larger
Battle of the Atlantic, where
Allied navies aimed to protect the North Atlantic convoys from German
U-boats.
Cold War Following the Second World War, most countries in the Americas, including every country in Central America, Mexico, and the United States, signed the
Inter-American Treaty of Reciprocal Assistance in 1947, a treaty that committed its signors to the doctrine of hemispheric defence. A similar treaty of collective defence between Canada and the United States was arranged through
NATO. In April 1948, the
Organization of American States was created during the Ninth
International Conference of American States held in
Bogotá, with member states pledging to fight
communism on the American continent. The
Truman administration supported the
National Liberation Party of
Costa Rica during the 1948
Costa Rican Civil War, as a result of their opposition to the communist government. In 1953, the first successful communist revolution occurred in the Americas, with the
Cuban Revolution. A US-sponsored counter-revolutionary invasion was repelled in 1961 during the
Bay of Pigs Invasion. The discovery of Soviet missiles in Cuba
in 1963 led to a standoff between the United States, and Cuba and the Soviet Union, known as the
Cuban Missile Crisis. The crisis escalated to the point where a
United States Navy quarantined Cuba. The crisis was eventually resolved when the
Khrushchev regime agreed to withdraw their missiles from the island, in exchange for the withdrawal of US missiles in Turkey, and Italy; as well as an agreement that the United States would not invade Cuba without direct provocation. The
Escambray rebellion was another
counter-revolutionary rebellion in the
Escambray Mountains of Cuba. Lasting for six years (1959–65). Throughout the Cold War-era, the United States, along with its allies in the Americas, staged military interventions in several countries in North America, in an effort to
contain communism. Military interventions of this nature include the
Dominican Civil War in 1963, and the
invasion of Grenada in 1983. As the
Central American crisis unraveled in the late 1970s, several Central American states including
El Salvador,
Guatemala, and
Nicaragua, saw
civil wars and pro-communist revolutions erupt in their country. Various factions involved in those conflicts saw support from either the United States, or the
Eastern Bloc, as the civil conflicts became
proxies of the larger
Cold War. In July 1969, the countries of
El Salvador and
Honduras fought a brief war known as the
Football War.
Post-Cold War-era The
Zapatista uprising of 1994 was a rebellion in
Chiapas, Mexico, coordinated by the
Zapatista Army of National Liberation. Launched in response to the implementation of the
North American Free Trade Agreement, the rebellion resulted in the
San Andrés Accords, granting a number of rights, autonomy, and recognition for the indigenous population of Chiapas.
Low-level skirmishes and violent incidents relating to the Zapatista uprising persisted in Chiapas. ==See also==
