Havana Harbor.
Havanna Harbor
At the time, Americans were on a very expansionistic path. They felt they had to start competing with the Imperialistic nations of Europe, and the remains of the Spanish empire looked like a great place to start. Tensions were very high, and when the American battleship Maine exploded in Havana harbor, it provided a spark to light the fire of war.
The sinking of the Maine was the cause and the US thought that Spain had used a mine to explode under the Maine.
The US wasn't at war when the USS Maine sunk. The Maine was on a "show the flag" visit to Havana at the time and at anchorage. The event of the Maine's sinking was a trigger event in the lead up to the Spanish-American War in which the US declared war on Spain and ended up with the Philippines, Cuba, and other former Spanish territories as protectorates. The sinking of the USS Maine has never been shown to be the result of Spanish actions or the Cuban revolutionaries, and is in dispute as to whether it was in fact an accident or not.
