When anti-corruption candidate Bernardo Arévalo won Guatemala’s presidency in August, his urban supporters took to the streets in celebration. Two months later, they are still there, not in celebration but in protest against challenges to Arévalo’s election led by the country’s attorney general. This month, the protests went national when Indigenous authorities called a strike demanding the attorney general’s resignation. The participation of Guatemala’s marginalized Indigenous peoples in nationwide protests holds both peril and promise. Instability in the impoverished rural hinterland could send additional waves of migrants toward the U.S. border. But the Indigenous population’s defense of elections could also prove a watershed moment for Guatemalan democracy.
