How did spanish-american war occur?

Answer 1

A wave of American support for Cuban independence from Spain caused tension between Spain and the US. American newspapers whipped up public opinion. An American warship on a peaceful visit to Havana exploded mysteriously. Without any substantial evidence, the American people and government blamed Spain. (The ship may have suffered a boiler explosion, its own powder might have detonated, or it may have hit a mine, but public opinion said it was a Spanish attack.)

The United States used this as a reason to invade Cuba and drive Spain out of its remaining colonies in the Americas and Philippines. Although Spain had held these territories firmly for hundreds of years, they were taken away very quickly by the American forces.

After the war, Cuba was briefly an American possession but there was never an intention to keep it. Cuba was made independent; however, the United States reversed an earlier commitment and created a plan to continue to exercise some control over Cuba after independence. Cuba would not be allowed to make international treaties and pacts, and would not be allowed to borrow money.

The unfairness of the reversal of policy (in continuing to limit Cuba's sovereignty) would go on to cause increasing tension between Cuba and the US, right up until the time of the Cuban Revolution in the late 1950s.

Cuba's sister Puerto Rico (they were called the two wings of a butterfly) remained in American hands. The Philippines and Guam also remained American territory, with Philippines becoming independent after WW2.
