As a result of the Treaty of Paris, which ended the Spanish-American war and was signed in 1898, Spain was officially forced out of North America.

The Treaty of Paris of 1898 is considered the end point of the overseas Spanish Empire and the beginning of the period of colonial power of the United States.

The Spanish-American war had had a quick and predictable outcome, due to the US arms superiority. At the end of July of 1898, and still in the heat of war, Spain began to negotiate the end of the hostilities by the French ambassador in Washington D.C., Jules Cambon.

Spain feared that the conflict would be transferred to the other side of the Atlantic and would endanger the Canary Islands, the Balearic Islands and other Spanish possessions in North Africa and Spanish Guinea.

At the end of the conflict Spain was defeated and its main results were the loss by the island of Cuba (which proclaimed itself an independent republic, but remained under the United States), as well as Puerto Rico, the Philippines and Guam, which they became colonial dependencies of the United States.
