 In 1921 several of these parties, including the Middle Class Party merged into the Liberal State Party, together with two larger liberal parties.The Middle Class Party continued as an independent part of this new party, with a separate list for the elections (some times combined with the Neutral Party).In 1929 this special position was abolished and Staalman left the Liberal State Party to found the Middle Party for City and Country, which won one seat in the 1929 elections.
