Nederlands Israëlitisch Kerkgenootschap

The Nederlands-Israëlitisch Kerkgenootschap (English: Dutch Israelite Religious Community) (NIK) is the umbrella organisation for most Ashkenazi Jewish communities in the Netherlands, and is Orthodox in nature, described as traditional in outlook. The expression Orthodox, is for the Dutch situation at least, of a later date than the existence of the congregations that make up the NIK and the NIK itself.
