Pro Patria Union
On 4 April 2006, representatives of the Pro Patria Union and the representatives of Res Publica decided to merge the two parties. The merger was approved by the general assemblies of both parties in Pärnu on 4 June 2006. Although originally the name "For Estonia" ("Eesti Eest") was considered for the united party, it was rejected. New party was officially registered on 15 October 2006 under the name Pro Patria and Res Publica Union.
