GreenLeft. The "new" generation has been very prominent: Ina Brouwer led the party in the 1994 elections and one of the party's senators Jos van der Lans was a member of the CPN. The former party chair who was very influential in the formulation of the new liberal course, Herman Meijer, was one of the gay rights activists who joined the CPN in the 1970s. Name The CPN changed its name two times. It was founded as Sociaal-Democratische Partij (Social-Democratic party; SDP). It followers were commonly known as 'Tribunists' after their main organ. After the Russian Revolution the term social-democracy became linked to the reformist socialists, while the term communist was linked to Leninist revolutionary socialism.

This led to a split when a group around a prominent ally of Trotsky, Henk Sneevliet, left the party to form the Revolutionary Socialist Party (RSP). In the 1960s the party did not choose sides in the conflict between the People's Republic of China and the USSR. Nevertheless, a Maoist group, called the Communist Unity Movement of the Netherlands split from the Party. In the 1970s and 1980s the Party began to
