The 1964 presidential election of Christian Democrat Eduardo Frei Montalva by an absolute majority initiated a period of major reform. Under the slogan "Revolution in Liberty", the Frei administration embarked on far-reaching social and economic programs, particularly in education, housing, and agrarian reform, including rural unionization of agricultural workers. By 1967, however, Frei encountered increasing opposition from leftists, who charged that his reforms were inadequate, and from conservatives, who found them excessive. At the end of his term, Frei had not fully achieved his party's ambitious goals.
