Democratic Alliance (Bulgaria)

The Military League and the People's Alliance, organisers of the coup of 9 June 1923 that overthrew Stamboliyski, wanted a party to give the new regime a parliamentary base. When the Constitutional Bloc dissolved in late July, the Democratic, Radical Democratic and United People's Progressive parties formed a Union for Democracy, which on 10 August merged with the People's Alliance into the Democratic Alliance. Its first executive bureau had two members from each of the four organisations; the Radical Democrats sent Petko Stoyanov and Nikola Naydenov.

Discontent with the centralisation of the organisation into a single party led many Democrats and Radical Democrats to leave in early 1924 and re-establish their old parties. Within the Alliance the Tsankov faction from the former People's Alliance, the Lyapchev faction from the Democrats and the Atanas Burov faction from the United People's Progressives constantly clashed. After the harsh repression of Tsankov's government (1923–1926) Lyapchev became prime minister in early 1926, and in 1928 Tsankov's supporters and the newly founded Political Circle Zveno voted against the stabilisation loan.

The party governed in coalition with the Social Democrats in 1923–1926, alone in 1926–1930 and with the National Liberals in 1930–1931. After its defeat in the 1931 election the Tsankov wing split off in 1932 to form the National Social Movement, and the party ceased to exist when parties were banned after the coup of 19 May 1934; some leaders remained active in the opposition "Five" (Petorka). Petko Stainov was minister of railways, posts and telegraphs in Lyapchev's third cabinet of 1930–1931.
