History
The village was first mentioned in the 13th century as Ytzinghahusum, and means "settlement of the people of Idse (person)". Idsegahuizum is a terp (artificial living hill) village which is located near the former Zuiderzee (nowadays: IJsselmeer). It is an agricultural community which specialises in potatoes and gladioli. The village could only be reached via the sea dike. Between 1876 and 1879, the Makkumermeer was poldered and road was built to Allingawier and the world beyond.
The Dutch Reformed church was built in 1870 as a replacement of a medieval church. In 1874, a nearly identical church was built in Hieslum.
Idsegahuizum was home to 77 people in 1840. Before 2011, the village was part of the Wûnseradiel municipality.
