In October and November 2006, CIDOB, the Bolivian Landless Workers Movement (MST-Bolivia), highland indigenous groups, and others joined in a National March for Land and Territory. This 28-day march was designed to propel the passage of a new land reform law, then mired in Bolivia's National Congress. After 2,000 marchers arrived in El Alto on November 27, they were joined by tens of thousands of other demonstrators in marching to La Paz's Plaza San Francisco, and on to the Plaza Murillo before the National Congress building where they set up a tent city. The encampment continued until the passage of a new land reform law.
