Premise: In 1856 Manuel Ruiz Zorrilla was elected deputy, and soon attracted notice among the most advanced Progressists and Democrats. He took part in the revolutionary propaganda that led to the military movement in Madrid on June 22, 1866. He had to take refuge in France for two years, like his fellow-conspirators, and only returned to Spain when the revolution of 1868 took place.
Hypothesis: Zorrilla started the revolution of 1868.
