"Las Madres de la Plaza de Mayo On every Thursday for the past 40 years, women have walked a picket line around Buenos Aires’s most politically significant plaza. They call themselves Las Madres de la Plaza de Mayo, and each mother present has lost a son or a daughter, presumably “disappeared” at the hands of the nation’s 1970s-era military dictatorships. Some days only a half-dozen mothers lead the march; though increasingly elderly, they are still determined to carry on the fight against all forms of oppression. You’d expect it to be a depressing affair, but in fact it’s quite moving to see the crowd of 50 or more supporters march beside the original mothers as they chant, demanding accountability for one of Latin America’s most shameful and violent historical episodes.
