Holland is a geographical region and former province on the western coast of the Netherlands. From the 10th to the 16th century, Holland proper was a unified political region within the Holy Roman Empire as a county ruled by the counts of Holland. By the 17th century, the province of Holland had risen to become a maritime and economic power, dominating the other provinces of the newly independent Dutch Republic.

There are twelve provinces of the Netherlands representing the administrative layer between the national government and the local governments, with responsibility for matters of subnational or regional importance.
