The Pro Patria Union was a national conservative political party in Estonia that was active from 1995 to 2006. The party succeeded the Pro Patria National Coalition, which had been founded in 1992. The party's programme was based upon Christian democracy and nationalism, and it was the main force behind the economic and legal reforms in Estonia at the beginning of the 1990s. In 2006, the Pro Patria Union and the Res Publica Party agreed to merge the two parties, creating the Pro Patria and Res Publica Union.
