Rheden and Wordrheden are considered separate marks by Sloet. Van Sevenhoven claims they are one mark, there was a division between the two in 1840, but there was never an agreement on the border between the marks. The Maalschappen Rheder-, and Wordrhederbos became part of the mark in the late 16th or early 17th century. The influence of the ambtsjonkers in the mark grew substantially in the 18th century. Forced division. The Rhederlaag/Mars had a separate management but according to van Sevenhoven it was still part off the mark.
