Parti démocratique sénégalais
Senghor was considerably more tolerant of opposition than most African leaders became in the 1960s. Nonetheless, political activity was somewhat restricted for a time. Senghor's party, the Senegalese Progressive Union (now the [[Socialist Party of Senegal]]), was the only legally permitted party from 1965 until 1975. In the latter year, Senghor allowed the formation of two opposition parties that began operation in 1976—a Marxist party (the [[African Independence Party – Renewal|African Independence Party]]) and a liberal party (the [[Senegalese Democratic Party]]).
