The first general strike in Uruguayan history, which completely paralyzed Montevideo for three days in May 1911, provides a useful vantage point from which to view the transformation of the third largest capital in South America from a sleepy “Belle Epoque” horse town into a modern, cosmopolitan city. Coming many years after general strikes in Buenos Aires, São Paulo and Rio de Janeiro, the 1911 Montevideo conflict appeared to erupt virtually overnight, at a moment when the labor movement itself was in some disarray, and caught the city by surprise. Merchants closed their doors, transport ground to a halt, and theaters and cinemas remained dark as the city became strangely quiet. An estimated 50,000-60,000 workers in 37 unions left their jobs in factories, breweries, frigoríficos, stores, and newspapers. In the words of a journalist for a conservative daily paper, “every sign of activity vanished from the city as completely as if it had been stricken by a pestilence—as in truth it was.” The anarchist labor confederation, which organized the mass strike, took over control of the streets and the food supply, and vehicles were only allowed to run with its authorization, thus inverting the city's power structure, at least temporarily.
