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.
