Dolores Huerta, the celebrated 1960s labor union leader and civil rights activist, died on Wednesday in California at the age of 96, her family said in a statement.

Huerta was a co-founder with Cesar Chavez, another veteran unionist and political activist, of the United Farm Workers union (UFW), which was credited with improving pay and conditions for agricultural workers through a series of strikes, boycotts and protests in the 1960s and 1970s.

Despite structural differences between countries, protests are a reminder of what makes demonstrations so powerful

Since mid-September, students in metropolitan France have been mobilizing against poor conditions in public high schools. The mouvement lycéen has spread from a single campus in a Parisian suburb to include high schoolers and university students nationwide, with public sector workers, climate activists, labor unions and everyday people joining in solidarity. The unifying concerns have largely centered on the climbing costs of daily life, shrinking funds for social services and general anxiety about the future.

For two weekends running, France has seen hundreds of thousands of people take to the streets: first on 17 October, when a day of largely peaceful gatherings ended in looting and vandalism; then on 24 October, as the state met the movement with aggressive policing and protest bans intended to keep people at home.
