|Merger of||Estonian Democratic Party|
Estonian Radical Democratic Party
|Merged into||United Nationalist Party|
The party was established in March 1919 by a merger of the Estonian Democratic Party and the Estonian Radical Democratic Party. Some right-wing members of the Democratic Party opposed merging with the Radical Democrats and broke away to form the Christian Democratic Party. In the April 1919 Constituent Assembly elections the new party won 25 of the 120 seats, becoming the third-largest party in the Assembly.
