الحزب الاشتراكي اليمني
In June 1969, a radical Marxist wing of the NLF gained power and changed the country's name to the People's Democratic Republic of Yemen (PDRY) on 1 December 1970. In the PDRY, all political parties were amalgamated into the Yemeni Socialist Party (YSP), which became the only legal party. The PDRY established close ties with the Soviet Union, the People's Republic of China, Cuba, and radical Palestinians.
