The sinking of the USS Maine is considered to be the event that sparked the beginning of the Spanish American War. On February 15, 1898, the USS Maine, an American battleship, exploded and sank in the Havana Harbor, Cuba. This incident led to a public outcry in the United States, with many believing that the explosion was caused by a Spanish mine. The sinking of the USS Maine significantly increased tensions between the United States and Spain, ultimately leading to the outbreak of the Spanish American War in April 1898.
