Modern diplomatic relations between Cuba and the United States are cold, stemming from historic conflict and divergent political ideologies. The two nations restored diplomatic relations on July 20, 2015, after relations had been severed in 1961 during the Cold War. The U.S. has maintained a comprehensive trade embargo against Cuba since 1960. The embargo includes restrictions on all commercial, economic, and financial activity, making it illegal for U.S. corporations to do business with Cuba.
Early 19th century relations centered mainly on extensive trade, before manifest destiny increasingly led to an American desire to buy, conquer, or control Cuba. The U.S. attempted to purchase Cuba in 1848 and in 1854 from Spain. It successfully took over Cuba in 1898 as a U.S. territory within the Treaty of Paris. The U.S. position of economic and political dominance over the island persisted after Cuba became formally independent in 1902. Relations became closer still as the U.S. provided weapons, money, and its authority to the military dictatorship of Fulgencio Batista that ruled Cuba from 1952 to 1958. They deteriorated during the Cuban Revolution of 1959. The U.S. recruited operatives in Cuba to carry out a violent campaign of terrorism and sabotage on the island, killing civilians and causing economic damage.
