Holland is the name of a region in the western part of the Netherlands. Holland was a county of the Holy Roman Empire and later the leading province of the Republic of the Seven United Netherlands (1581–1795).Today, there are two provinces called Holland in the Netherlands: North Holland (Noord-Holland) and South Holland (Zuid-Holland). Those provinces were created in 1840. The earlier country and province of Holland used to be greater, but some Hollandic parts were given to other provinces during the French occupation (1795-1813). Willemstad became part of North Brabant, the islands of Vlieland and Terschelling were given to Friesland, and the island of Urk to Overijssel.
