April 21, 1898 ~ August 13, 1898

Hostilities began in the aftermath of the internal explosion of the USS Maine

in Havana Harbor in Cuba,

leading to U.S. intervention in the Cuban War of Independence.

The main issue was Cuban independence.

Revolts had been occurring for some years in Cuba against Spanish rule.

U.S. victory allowed the U.S, temporary control of Cuba,

and ceded ownership of Puerto Rico, Guam and the Philippine islands.
