What were the three main reasons US went to war with Spain in 1890s?

The United States did not go to war with Spain in the 1890s. The Spanish–American War took place in 1898, and the main reasons for the US involvement were:

- The sinking of the USS Maine in Havana harbor, leading to the deaths of 260 American sailors.

- Cuba being a former Spanish colony fighting for its independence for several years under the leadership of José Martí.

- America having economic interests in Cuba, such as the plantations owned by American citizens and the potential market for American goods.

- The rise of yellow journalism and the influence of the sensationalist newspapers of William Randolph Hearst and Joseph Pulitzer, which fueled public support for war.
