The '''Social Democratic Party''' (French: Parti Social-Démocrate; Mandarin: 社会民主党/Shèhuì mínzhǔdǎng) was a [[Gramontism|Gramontist]], social-democratic [[Laeral|Laeralian]] political party which was the dominant party in the autocratic [[Republican Era]]. Established in 1922 by the former ''Committee for Democracy and Progress'' upon their victory in the [[Laeralian Civil War]], the party used malapportionment, vote-buying, and the suppression of political opponents to remain the dominant party in Laeral until the party's schism at the ''Seventh Social Democratic Party Congress'' in 1952 and the ensuing [[Bloody Summer]], which led to the writing of the 1954 Laeralian Constitution and the transition to full democracy. 

The SDP was a center-left to left-wing political party based upon [[Gramontism]] and the [[Gang of Five|Five Pillars]] espoused by the party's founding elite, the [[Gang of Five]]. These principles of republicanism, reformism, socialism, secularism, and anti-imperialism were enacted through the [[Rose Revolution]], a series of social reforms taking place throughout Laeral's Republican Era. A schism in the party between pro-democracy and hardliner factions led to the decisive victory of [[Sun Jia-wei]]'s reformist "scarlet" faction following the [[Bloody Summer]], leading to the first fully-free elections in 1954. The party initially received electoral success even once free elections had been instituted, forming majority governments in the [[National Assembly (Laeral)|National Assembly]] until 1964. However, the excesses of the [[Emergency Period]], when [[Réne Gramont|Social Democratic President Réne Gramont]] suspended civil liberties, led the party to officially reconstitute itself as the [[Republic Party (Laeral)|Republic Party]] in 1965. Today, the Social Democratic legacy remains a matter of contention in Laeral, while the [[Progressive Party of Laeral|Progressive Party]] identifies itself as the spiritual successor to the SDP.
