Pro Patria Union
Res Publica Party () was a political party in Estonia that self-identified as conservative and therefore member of the International Democrat Union, but considering its vague platform for 2003 election, the genuineness of this ideology is disputed. Established as a party on 8 December 2001, the political organisation Res Publica was founded already as early as 1989 and existed as a community of young conservatives, mostly associated with the Pro Patria Union party during the 1990s. Res Publica was a member of the EPP (European People's Party) on the European level. It merged with Pro Patria Union in 2006 to form the Pro Patria and Res Publica Union.
