The Counts of Holland were the rulers of the historical region of Holland in the Low Countries, which is now part of modern-day Netherlands. This title originated in the 10th century and was held by various noble families, most notably the House of Holland. The counts played a significant role in the political and economic development of the region, particularly during the Middle Ages. Over time, the power of the Counts of Holland grew, leading to the establishment of a more centralized authority. Their influence extended beyond Holland, impacting neighboring regions and contributing to the formation of the Duchy of Brabant and the County of Flanders. The title eventually became part of the larger Duchy of Burgundy and later the Habsburg Empire.
