Filipino community organizers melded Alinsky's ideas with concepts from liberation theology, a pro-poor theological movement in the developing world, and the philosophy of Brazilian educationalist Paulo Freire. They found this community organizing a well-suited method to work among the poor during the martial law era of the dictator Ferdinand Marcos. Unlike the communist guerrillas, community organizers quietly worked to encourage critical thinking about the status quo, facilitate organization and the support the solving of concrete collective problems. Community organizing was thus able to lay the groundwork for the People Power Revolution of 1986, which nonviolently pushed Marcos out of power.
