The original name of the church was Christian Reformed Church in the Netherlands (Christelijke Gereformeerde Kerk in Nederland, CGKN). The church was formed in 1869 by the merger of two churches, the Reformed churches under the cross and the separated Christian congregations, both separated from the Dutch Reformed Church in 1834. Most of the CGKN merged into the Reformed Churches in the Netherlands in 1892; a small part remained independent, and carried this name until it was renamed in 1947 to Christian Reformed Churches. At the first Synod 8 congregations were represented. A Theological Seminary was opened in The Hague and later was moved to Apeldoorn in 1919. Since then the churches grew steadily till 1985, when membership was 75,000, and today membership fluctuates around this number. It has 11 Classes. The church withdrew from the Reformed Ecumenical Council in 1989, and joined the International Conference of Reformed Churches in 1995.
