The biggest and most significant of the Latino-American social movements took place outside Latin America. For several weeks, from March to May 2006, millions of “legal” and more often “illegal,” immigrants demonstrated peacefully in more than 120 towns throughout the United States. This is more than were present during the civil rights demonstrations in the 1950s and 1960s, or those against the Vietnam War at the end of the 1960s and the beginning of the 1970s. Indeed, the two months of the “Latino Spring” was the most intense period of social mobilization, strictly speaking, ever experienced in American history.
