The Count of Holland was a title held by the rulers of the historical region of Holland, which is now part of the Netherlands. The title emerged in the 10th century and was significant in the development of the Dutch state. Counts governed the area, managing local affairs and representing the region in broader political matters. Over time, the title evolved, and the Counts of Holland played a crucial role in the formation of the Duchy of Brabant and the County of Flanders. The last Count, William IV, became the first Duke of Burgundy, marking a shift in power and influence in the region.
