History
Until 1948 was Mûnein a part of Oentsjerk. At the request of "Dorpsbelang" (Village Interest) Mûnein received village status. Until then, it was customary for village status to be given to areas with a church which Mûnein did not have. But because there is a pub, a primary school and several associations, the municipality Tytsjerksteradiel gave village status on 8 October 1948.
