The Free-thinking Democratic League was a progressive liberal political party in the Netherlands. Established in 1901, it played a relatively large role in Dutch politics, supplying one Prime Minister, Wim Schermerhorn. The League is a predecessor of two of the major Dutch political parties, the conservative liberal People's Party for Freedom and Democracy (VVD) and the social democratic Labour Party (PvdA). The social liberal Democrats 66 also claims that it and the VDB are ideologically connected.
