Was Cesar Chavez the first Latino political leader?

Cesar Chavez was not the first Latino political leader; however, he was one of the most prominent figures in the American labor movement and a significant advocate for Latino rights in the 20th century. His leadership in founding the United Farm Workers (UFW) in the 1960s helped elevate issues affecting farmworkers, particularly those of Latino descent. While there were earlier Latino leaders in politics and civil rights, Chavez's impact on labor rights and social justice made him a key figure in American history.
