 William was designated a "Child of State" in 1660, implying he would be trained for high office by the States-General.When Mary died in 1661, she named Charles as a guardian of William, allowing England a measure of influence in Dutch politics.The Dutch, in a move coordinated by Cornelis and Andries de Graeff, tried to placate the king with prodigious gifts, such as the Dutch Gift of 1660.
