The Libertarian Party is one of the three largest political parties in the Kingdom of Sierra. Founded in 1967, the Libertarian Party quickly propelled into Sierran politics with its rapidly rising membership base. Since the 1990s, the Libertarian Party destroyed Sierra's historical two-party systemand replacing it with the present-day three-party system. While the party promotes and represents a wide range of schools and disciplines of libertarianism (notably excluding libertarian socialism and other left ideologies), officially, it promotes lasseiz-faire free markets and extensive civil liberties.
