The Democratic Party, officially known as the Portuguese Republican Party, was a Portuguesecentre-leftpolitical party during the Portuguese First Republic. It was also the self-proclaimed successor to the original Portuguese Republican Party, which had been behind the revolution that established the Portuguese First Republic in 1910. The name "Democratic Party" was never the official name of the party, as the Portuguese Republican Party never ceased to exist. However, the party was de facto different and thus the other parties used the new expression to assert their opposition to the claim of continuation of the PRP by Afonso Costa, the first leader of the Democratic Party. Other names were given to the members of the Democratic Party, like the Afonsists, named after Afonso Costa.
History
When the Evolutionists and Unionists seceded from the Portuguese Republican Party in February 1912, the Democratic Party declared itself the latter party's heir. It soon controlled its electoral and propagandistic structure, a fact that would influence the dominance of the Democratic Party during the First Republic. During the First Republic, the Democratic Party, led by Afonso Costa, managed to hold power despite suffering several revolutionary attempts, both monarchist and republican. Although some of the coups partially succeeded the Democratic Party always managed to retain power. During World War I, in which Portugal participated, the party entered a coalition government with the Evolutionist Party called "Sacred Union", to face the problems of the war. Following the war, discontent grew and the union was eventually dissolved. Sidónio took advantage of this and established a dictatorial government of his National Republican Party. Sidónio Pais was assassinated 14 December 1918. By 1919 the Democratic Party was again in power. After 1919, with Afonso Costa in Paris, the party was led by António Maria da Silva. In the next phase of the party's existence, political, popular and syndicalist opposition created a climate of constant revolt. Groups also seceded from the party, with the creation of the Democratic Leftwing Republican Party and the Reformist Party, both on the Left.
The identification of the First Republic with the Democratic Party was so close, as the party dominated all political life between 1911 and 1926, that Marcelo Rebelo de Sousa described it as a "multi-party system with a dominant party" and historian Fernando Rosas called it a "political monopoly" and a "democratic dictatorship".
