The Hageland is a landscape in the Flemish Region of Belgium, situated in the eastern part of the Province of Flemish Brabant. It is mainly comprised between the cities of Aarschot, Leuven, Tienen and Diest, and probably coincides to some extent with the twelfth-century County of Leuven. The French Government that controlled the area that later became Belgium in the last years of the 18th and early 19th century, had extended Limburg, which since then comprises the minor part of the Hageland at the city of Halen.
The name refers to land with dense (low) forest and/or undergrowth. Its earliest attestation (spelled as Hagelant) dates from 1528.[1]
