Following Stalin's death in 1953, a political "thaw" allowed a more liberal faction of the Polish communists, led by Władysław Gomułka, to gain power. By the mid-1960s, Poland began experiencing increasing economic as well as political difficulties. They culminated in the 1968 Polish political crisis and the 1970 Polish protests when a consumer price hike led to a wave of strikes. The government introduced a new economic program based on large-scale loans from western creditors, which resulted in a rise in living standards and expectations, but the program meant growing integration of Poland's economy with the world economy and it faltered after the 1973 oil crisis. In 1976, the government of Edward Gierek was forced to raise prices again which led to the June 1976 protests.
