"Sí, se puede" (Spanish for "Yes, it is possible" or, roughly, "Yes, we can"; ) is the motto of the United Farm Workers of America, and has since been taken up by other activist groups. In 1972, during César Chávez's 25-day fast in Phoenix, Arizona, UFW's co-founder, Dolores Huerta, came up with the slogan. "Sí se puede" has long been a UFW guiding principle that has served to inspire accomplishment of goals. The phrase is a federally registered trademark of the UFW.
