The Kleve region consists of the following entities as they stood in 1789:
- The Duchy of Cleves (the English rendition of Kleve),
- The Principality of Moers,
- The portion of the Duchy of Guelders within the modern boundaries of the Federal Republic of Germany,
- The Lordship of Anholt, and
- The Abbacy of Elten.
The starting dates for the database vary by entity as follows:
- Cleves—1521, when the Markian dynasty inherited the Duchy of Jülich-Berg. (Unlike Jülich and Berg, that date has no particular significance for Cleves, but it provides a common starting date for all Markian entities.)
- Moers—1519, when the house of Neuenahr assumed control over the county.
- Guelders—1543, when the duchy definitively lost its independence and became part of the Spanish Netherlands.
- Anholt—1540, when it became an imperial fief, independent of both Guelders and Kleve.
- Elten—1473, when administrative responsibility fell to the Duchy of Cleves.
When the database ends depends on which side of the Rhein a place was located. For those on the left bank (west side), the database ends in 1794 when they were occupied by France. For those on the right bank (east side), the database ends in 1806, when the Holy Roman Empire was dissolved.
