Mexico in World War I

As the Revolution was unfolding in Mexico from 1910 to 1920, the first World War broke out in Europe, lasting from 1914 to 1918. Mexico benefited in some respects from the war, among them the greater demand for oil, as well as for other mineral resources, by the European powers, increasing the quantity of economic resources being obtained from these sources.

Germany, via the Zimmermann Telegram, proposed an alliance with Mexico for various reasons, such as its strategic position and its role as provider of oil to the allied powers. The proposal was rejected by Venustiano Carranza, leader of the Constitutionalist movement.
