The papers of Abraham Kuyper (1837-1920) were bequeathed to the Abraham Kuyper Stichting, the academic office of the Antirevolutionary Party, founded in 1922 and located in Kuyper’s former residence in The Hague. In 1971 the papers were transferred to the Historical Documentation Center for Dutch Protestantism (1800-present day) at the Vrije Universiteit Amsterdam, and kept as coll. nr. 154.
The papers have been digitized in a cooperative enterprise of the Historical Documentation Center, Princeton Theological Seminary and The Neo-Calvinism Research Institute (NRI) at Theological University Kampen, and made available to the general public by the NRI in 2020.
The archive holds almost 9.000 letters to Abraham Kuyper and many documents regarding his personal life and his family, and documents related to Kuyper’s activities as pastor, journalist, politician, university founder, professor, church leader, and author.
