The counts of Holland sought to expand their domain by conquering the free Frisian territories lying to the north and east of their existing holdings. The Frisians maintained a tradition of independence and resisted incorporation into Holland's feudal structure, creating persistent tension between the two parties.
The Friso-Hollandic Wars comprised a series of short medieval conflicts, ranging from single battles to full campaigns, waged intermittently across four distinct phases between 1256 and 1422. Holland repeatedly attempted military conquest of the free Frisian lands, while the Frisians defended their autonomy against each incursion.
Despite repeated military efforts by Holland, a definitive conquest of the free Frisian territories was not achieved, and a de facto state of conflict or rivalry between the County of Holland and the Frisian lands persisted well beyond 1500, leaving the question of Frisian independence unresolved for generations.
