The Dutch Reformed Church (Dutch: Nederlandse Hervormde Kerk, abbreviated NHK) was the largest Christian denomination in the Netherlands from the onset of the Protestant Reformation in the 16th century until 1930. It was the original denomination of the Dutch Royal Family and the foremost Protestant denomination until 2004. It was the larger of the two major Reformed denominations, after the Reformed Churches in the Netherlands (Gereformeerde kerk) was founded in 1892. It spread to the United States, South Africa, Indonesia, Sri Lanka, Brazil, and various other world regions through Dutch colonization. Allegiance to the Dutch Reformed Church was a common feature among Dutch immigrant communities around the world and became a crucial part of Afrikaner nationalism in South Africa.
