History
The party was established as a breakaway from the Bulgarian Social Democratic Workers Party (Broad Socialists) following the 1923 coup, and was initially allied with the Democratic Alliance.[1]
The party first contested national elections alone in 1931, when it ran in the National Assembly elections,[2] but failed to win a seat.[3]
Between 1945 and 1947 the ORSDP was allied with Bulgarian Agrarian People's Union "Nikola Petkov",[1] with the parties running a joint list in the 1946 Constitutional Assembly election. The joint list finished in second place with 101 seats.[4] The following year a Communist regime was established.[5]
