The original National Democratic Party was active in the early 1920s.
The 1922 elections saw the party run alone in single-member constituencies, but on a joint list with the Independent Party of Smallholders, Workers and Citizens in multi-member constituencies in and around Budapest.
The 1926 elections saw the party run only in alliance with the Independent Party of Smallholders, Workers and Citizens under the name "United Left", with the joint list winning nine seats.
A new party was established in March 1996,[2] but did not contest any national elections.
