The Friso-Hollandic Wars, also called Frisian-Hollandic Wars, are a series of short medieval wars (ranging from single battles to entire campaigns) consisting of the attempts made by the counts of Holland to conquer the free Frisian territories, which lie to the north and east of their domain.
These wars ware waged off and on from 1256 to 1297, 1324 to 1348, 1396 to 1411, and from 1421 to 1422, although it could be argued that a state of war continues to exist between the County of Holland and the Frisian territories until well after the year 1500.
