The period following Novotný's downfall became known as the Prague Spring. During this time, Dubček and other reformers sought to liberalize the Communist government—creating "socialism with a human face". Though this loosened the party's influence on the country, Dubček remained a devoted Communist and intended to preserve the party's rule. However, during the Prague Spring, he and other reform-minded Communists sought to win popular support for the Communist government by eliminating its worst, most repressive features, allowing greater freedom of expression and tolerating political and social organizations not under Communist control. "Dubček! Svoboda!" became the popular refrain of student demonstrations during this period, while a poll gave him 78% public support. Yet Dubček found himself in an increasingly untenable position. The program of reform gained momentum, leading to pressures for further liberalization and democratization. At the same time, hard-line Communists in Czechoslovakia and the Leaders of other Warsaw Pact countries pressured Dubček to rein in the Prague Spring. Though Dubček wanted to oversee the reform movement, he refused to resort to any draconian measures to do so, while still stressing the leading role of the Party and the centrality of the Warsaw Pact.
