Loosduinen (electoral district)

Fully located in the province of South Holland, it included the municipality of Loosduinen, today a part of The Hague, as well as the modern municipalities of Westland, Maassluis, Midden-Delfland, Rijswijk and Zoetermeer, and the villages of Nootdorp, Voorburg, Stompwijk and Benthuizen.

Catholics formed a significant majority in the district, though dropping slightly from 36% in 1888 to 33% in 1909.

[3] The district of Loosduinen was abolished upon the introduction of party-list proportional representation in 1918.

[4] Loosduinen was a safe seat for the parliamentary right, though as a result of the district's religiously mixed population, it was contested between the Catholics and the Protestant Anti-Revolutionary Party in its early elections.

In 1897, Van Berckel was defeated in the second round by the Anti-Revolutionary Anthony Brummelkamp Jr., who would continue to represent Loosduinen for the following two decades, until its abolition in 1918.
