Count William III of Holland, also known as William of Orange, was a significant figure in the late 16th and early 17th centuries. He played a crucial role in the struggle for Dutch independence from Spanish rule during the Eighty Years' War. His leadership and vision helped to unite various provinces in the fight against oppression. In 1579, William was instrumental in the formation of the Union of Utrecht, which laid the foundation for the modern Netherlands. His efforts ultimately led to the recognition of Dutch independence in 1648, marking a pivotal moment in European history. William III is often celebrated as a national hero in the Netherlands.
