Cameroon political parties constitute an integral aspect of the political system of the country. Till 1990, the Cameroon National Union was the only legal political party in Cameroon. Today the country comprises a large number of political parties that play significant roles in the country's politics. The Cameroon National Union was created in 1966 with Ahmadou Ahidjo as its first leader. Several parties were merged to form the Cameroon National Union, also called Cameroon People's Democratic Movement (CPDM).
It was much later in 1990 when other political parties in Cameroon were formed. These were all opposition parties. Cameroon political parties that emerged, besides the Cameroon National Union, include National Union for Democracy and Progress or UNDP, Union of Cameroonian Populations or UPC and the Movement for the Defense of the Republic or MDR.
Other political parties of Cameroon are Social Democratic Front (SDF), Movement for Liberation and Development of Cameroon (MLDC), Movement for the Youth of Cameroon (MYC) etc. Amongst all these, the CPDM holds the strongest political position and the maximum number of votes in majority of the elections. Thus, it can be noticed that despite the existence of a number of Cameroon political parties, the CPDM has always dominated the political system.
