The Liberal Union (Dutch: Liberale Unie) was a conservative liberalpolitical party in the Netherlands. A major party in its time, the Liberals were one of the historic predecessors of the Liberal State Party, and therefore of the People's Party for Freedom and Democracy.
Liberals had been an important political force in the Netherlands. Since 1848 they were the dominant political force. They were organized in loose political clubs and caucuses. Liberals were divided between progressive, centrist and conservative liberals, but because of the lack of organized political parties, these divisions were not very strong. In 1879 the division became explicit when a separate parliamentary party was formed by supporters of Kappeyne van de Copello. With the rise of both catholic and protestant parties, the liberals were forced to organize themselves better.
In 1885 all the liberal political clubs and caucuses were united in the Liberal Union. The Union was factionalized: it had a progressive, a conservative and a centrist faction.
In 1888 the liberals were forced into opposition by a majority of the confessional political parties. In 1891 the confessional parties lost their majority and a liberal cabinet led by Van Tienhoven is formed. The cabinet's most important proposal is the relaxation of the census, proposed by minister of home affairs Tak: the law would grant the right to vote to all men able to read and write. All political parties were divided on the subject and with a very narrow majority the proposal was rejected. In reaction to this the cabinet resigns and new elections are held. In these elections the division between pro-suffrage Takkians and anti-suffrage anti-Takkians grows. The Liberal Union is also split on the subject. A group of conservative liberals leaves the party. They remained a loose political club until 1906, when they founded the League of Free Liberals.
