You are likely referring to Emiliano Zapata, a key figure in the Mexican Revolution. Initially, he received some support from the U.S. in his fight against the Mexican government, particularly in opposition to the oppressive regimes of leaders like Porfirio Díaz. However, as the revolution progressed, he found himself in conflict with American interests in Mexico, especially regarding land reforms and the exploitation of resources.
