The Rassemblement Démocratique du Dahomé (RDD, Dahomey Democratic Rally) was a political party in Dahomey (now Benin). It was formed and led by Hubert Maga and was based in northern Dahomey -- Dahomey's politics were intensively regional at that time.
Between 1961 and 1963, during Maga's first stint as president, the RDD became the sole political party in a one-party state. When Maga was ousted in 1963 by Colonel Christophe Soglo the RDD became the official opposition party, but Solgo later banned all political parties in the country.
The RDD returned to power in 1970 when Maga became chairman of the presidential council, until his two year term of office came to an end. In 1972 a military coup by Mathieu Kérékou once again resulted in the banning of political parties.
