The native Amerindian population of Cuba began to decline after the European discovery of the island by Christopher COLUMBUS in 1492 and following its development as a Spanish colony during the next several centuries. Large numbers of African slaves were imported to work the coffee and sugar plantations, and Havana became the launching point for the annual treasure fleets bound for Spain from Mexico and Peru. Spanish rule eventually provoked an independence movement and occasional rebellions that were harshly suppressed. US intervention during the Spanish-American War in 1898 assisted the Cubans in overthrowing Spanish rule. The Treaty of Paris established Cuban independence from Spain in 1898 and, following three-and-a-half years of subsequent US military rule, Cuba became an independent republic in 1902 after which the island experienced a string of governments mostly dominated by the military and corrupt politicians. Fidel CASTRO led a rebel army to victory in 1959; his authoritarian rule held the subsequent regime together for nearly five decades. He stepped down as president in February 2008 in favor of his younger brother Raul CASTRO. Cuba's communist revolution, with Soviet support, was exported throughout Latin America and Africa during the 1960s, 1970s, and 1980s. Miguel DIAZ-CANEL Bermudez, hand-picked by Raul CASTRO to succeed him, was approved as president by the National Assembly and took office on 19 April 2018.
The country faced a severe economic downturn in 1990 following the withdrawal of former Soviet subsidies worth $4-6 billion annually. Cuba at times portrays the US embargo, in place since 1961, as the source of its difficulties. Over the past decade, there has been growing communication with the Cuban Government to address national interests. As a result of efforts begun in December 2014 to re-establish diplomatic relations with the Cuban Government, which were severed in January 1961, the US and Cuba reopened embassies in their respective countries on 20 July 2015. However, the embargo remains in place.
Illicit migration of Cuban nationals to the US via maritime and overland routes has been a longstanding challenge. On 12 January 2017, the US and Cuba signed a Joint Statement ending the so-called "wet-foot, dry-foot" policy – by which Cuban nationals who reached US soil were permitted to stay – facilitating the repatriation of Cuban migrants. Illicit Cuban migration has since dropped significantly. In FY 2017, the US Coast Guard interdicted 1,606 Cuban nationals at sea. Also in FY 2017, 20,995 Cuban migrants presented themselves at various land border ports of entry throughout the US.
