He is, or was, Emiliano Zapata, the leader of the Southern Revolutionary Army. He lead mostly an army of peasants and workers in the southern part of Mexico, mainly in chiapas and Oaxaca.
If you ever heard the slogan "Land and Liberty" it was actually made by him, or his army. Also he was pretty based as far as I know, he wanted to redistribute land and end thw cacique and hacienda system, which was like slavery but with extra steps.
He was murdered by the carrancista army and the southern revolutionary army disbanded along, this was due a buncj lf factors, mainly because Carranza wanted to consolidate its power after the Decena Tragica, in which Francisco I. Madero was also murdered, by I cant quite remembrr his name.
At the end, the murder of Zapata and Villa left the revolution under control of the carranzista forces.
