Sí, se puede (Spanish for "Yes, it can be done") is the motto of the United Farm Workers. In 1972, during Cesar Chavez's 24 day fast in Phoenix, Arizona, he and UFW's co-founder, Dolores Huerta came up with the slogan.
The phrase has been widely adopted by other labor unions and civil rights organizations and drew widespread political and media attention as a rallying cry during the 2006 U.S. immigration reform protests.
Sí se puede is usually translated in English as "yes, we can", or "yes you can". The more literal translation that the United Farm Workers uses is "Yes, it can be done!"
President Barack Obama adopted the English version "Yes, we can!" first during the 2004 Illinois Democratic primary race for U.S. Senate, and it became a slogan of his 2008 presidential campaign.
