The House of Navarre was a royal dynasty that originated in the Kingdom of Navarre, located in the northern part of modern-day Spain and southern France. It played a significant role in the history of the region, especially during the Middle Ages, when it was a center of political and cultural activity. The house is known for its connections to various European royal families through marriage alliances. In 1512, the Kingdom of Navarre was invaded by the Kingdom of Castile, leading to its eventual annexation. Despite this, the House of Navarre continued to exist as a noble lineage, with notable figures such as Henry IV of France, who was born into the house. The legacy of the house remains significant in the context of Spanish and French history.
