The September 11, 1973 coup that overthrew Salvador Allende’s Unidad Popular government signaled the end of a radical political experiment, a “democratic road to socialism.” In its 1,000 days in power, Allende’s coalition state instituted a series of substantial political and economic changes, including the socialization of industries, agrarian reform, and the redistribution of wealth and authority. Unidad Popular faced fierce challenges from an increasingly mobilized opposition, who mounted campaigns in congress and in public space that fomented a climate of crisis in which the military might intervene. It also faced pressures from its own supporters, who occupied factories, lands, and city spaces in an effort to convince the state to radicalize the pace of change. Ruthless military intervention sought to “turn back” the political gains of the twentieth century that had reached their apex under Allende, and the military regime headed by Augusto Pinochet turned again and again to state-sponsored terror to entrench a “foundational project” that couple political authoritarianism with a neoliberal economy.
