When protest movements spread through cities around the world in 1968, Octavio Paz looked upon the “great youth rebellions . . . from afar,” he wrote, “with astonishment and with hope.” The poet was then Mexico’s ambassador to India. He escaped the summer heat of New Delhi into the foothills of the Himalayas, following developments on the radio. Soon, he learned that Mexico had joined the rebellions. Mexico would host the Olympics in October. As protests grew entrenched, and students threatened to disrupt the games, government repression intensified. On October 2, hundreds of student protesters were killed at Mexico’s City’s Tlatelolco Plaza. Hearing the grim news, Ambassador Paz’s response was a swift vote of no confidence, a letter of unambiguous dissent. It was, as he described the rebellions themselves, the merging of poetry and action, a merger he constantly craved.
