 When in 1828 Breust and Oost became part of the Eijsden municipality, Maarland (which has no basic school, nor a church of its own) was added to Oost.Thus until January 1, 2011 Oost-Maarland was part of the Eijsden municipality; on that date this municipality merged with the neighbouring one of Margraten.From January 1, 2018, the Netherlands and Belgium peacefully swapped territory on the River Meuse just west from Maarland, in an agreement signed in 2016.
