Isamaaliit
On 4 April 2006, representatives of the Pro Patria Union and the representatives of Res Publica decided to merge the two parties. A decision was made to form a new party, named Pro Patria and Res Publica Union ("Isamaa ja Res Publica Liit"), after approval by general assemblies of both merging political forces. Approval was given by the general assemblies on 4 June 2006. The union took third place in the 2007 elections, which, though they resulted in a loss in the combined parties' strength in Parliament, was a stronger than expected showing.
