Why did Isaac Newton move from Cambridge to London in 1696?

In 1696, Isaac Newton moved from Cambridge to London to accept an appointment as the warden of the Royal Mint.1

Following the publication of his Principia, Newton had grown dissatisfied with the academic life at Cambridge and developed a desire for a change in environment. This ambition was encouraged by his friend, the Swiss mathematician Fatio de Duillier, and Newton actively sought a position in London through the influence of his friend and politician, Charles Montague (later Lord Halifax).1

Although he did not formally resign his Cambridge appointments until 1701, his move to London in 1696 marked the effective end of his primary creative scientific activity. In his new role, Newton transitioned from his academic career to a position of significant public responsibility, where he became actively involved in the great recoinage and the pursuit of counterfeiters.1
