A history of America Now I'm watching a series of documantary programmes about a history of immigration in the USA. One of the programmes shades the light on the immigration of Latinos in America. It's a well-known fact that Cuba was under the colonial rule of Spain in the 19th century, but Americans invested millions of dollars into tobacco and shugar on Cuba. When Spanish soldiers sent Cuban rebels to concentration camps to hold the power, the government of the USA used it as a pretext to invade Cuba. They called it "liberation". As an American military ship with 200 hundred sailors on board was destroyed in Havana, the USA declared war on Spain. They fought against Spaniards in the Philippines and on Cuba. At the end of the Spanish-American war they left the island (Cuba) to the local authorities, but they promised to intervene if there was a threat to its independence. The last gave them the right to intervene the affairs of Cuba. So factually Cuba became the vassal of US.
