Holland is a region and former province on the western coast of the Netherlands.The name Holland is also frequently used informally to refer to the whole of the country of the Netherlands .This usage is commonly accepted in other countries and is also commonly employed by the Dutch themselves However, some in the Netherlands, particularly those from regions outside Holland, may find it undesirable, even offensive or misrepresentative to use the term for the whole country. 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. The area of the former County of Holland roughly coincides with the two current Dutch provinces of North Holland and South Holland into which it was divided, and which together include the Netherlands' three largest cities: the capital city of Amsterdam; Rotterdam, home of Europe's largest port; and the seat of government of The Hague. Holland has a population of 6,583,534 as of November 2019, and a density of 1,203/km2 (3,120/sq mi).
