Far-left groups, most importantly the Portuguese Democratic Movement (Movimento Democrático Português--MDP), had considerable influence in the early part of the revolution. Consisting mostly of students and intellectuals, these groups were augmented by leftists from all over the world who flocked to Portugal to wÍÍÍÍitness and participate in the revolution. They often engaged in guerrilla tactics, street demonstrations, and takeovers of private lands and industries. On their own, these groups could mount major demonstrations in alliance with the PCP, they could be even more formidable. Since the heady revolutionary days of the mid-1970s, however, most of these groups have been absorbed into the larger parties or dissolved. As of the beginning of 1990s, some far-left groups were still active at the universities and in intellectual circles, but they were seen as a fringe phenomenon and lacked their former disruptive capacity.
