Guevara was a member of Fidel Castro's Communist guerilla movement that seized power in Cuba in 1959. Both during and after the revolution, Guevara was an important participant in Communist Red Terror.
After brief stints as president of the National Bank and Minister of Industries, Guevara did not settle in as part of the new Cuban government, and tried without success to stage Communist revolutions through guerilla warfare in various countries, notably the Democratic Republic of the Congo and Bolivia, where he was captured by a unit of the Bolivian Ranger Battalion advised by United States Green Berets on October 8, 1967, and executed the following day.
He is today a capitalist merchandising icon and his face is seen on mugs and t-shirts on young leftist students and radicals around the world.
There are numerous criticisms of Che Guevara and how he is depicted in leftist sources. See the "External links" section.
