Republic of Cuba (1902–1959)

The Republic of Cuba, covering the historical period in Cuban history between 1902 and 1959, was an island country comprised the island of Cuba, as well as Isla de la Juventud (after 1925) and several minor archipelagos. The period began in 1902 following the end of its first U.S. military occupation years after Cuba declared independence in 1898 from the Spanish Empire. This era included various changing governments and U.S. military occupations, and ended with the outbreak of the Cuban Revolution in 1959. During this period, the United States exerted great influence on Cuban politics, notably through the Platt Amendment.

The governments of Cuba between independence from Spain and the Revolution have been regarded as client state of the United States. From 1902 to 1934, Cuban and U.S. law included the Platt Amendment, which guaranteed the United States right to intervene in Cuba, making it a U.S. protectorate, and placed restrictions on Cuban foreign relations. In 1934, Cuba and the United States signed the Treaty of Relations in which Cuba was obligated to give preferential treatment of its economy to the United States, in exchange the United States gave Cuba a guaranteed 22 percent share of the U.S. sugar market that later was amended to a 49 percent share in 1949.

The country continued to use the 1940 Constitution until the new constitution was promulgated in 1976.
