Duke of Cambridge, one of several current royal dukedoms in the United Kingdom , is a hereditary title of specific rank of nobility in the British royal family. The title (named after the city of Cambridge in England) is heritable by male descendants by primogeniture, and has been conferred upon members of the British royal family several times. The title of Duke of Cambridge, first created in 1660, superseded an earlier title of Earl of Cambridge. The title became extinct several times before being revived in 2011, when Queen Elizabeth II bestowed it on her grandson Prince William on 29 April 2011 upon his marriage to Catherine Middleton. Catherine became known as the Duchess of Cambridge. History The title was first granted in 1660 by King Charles II (immediately following the Restoration of the monarchy) to his infant eldest nephew Charles Stuart (1660–1661), the first son of the Duke of York (later King James II), though he was never formally created Duke of Cambridge as he died at the age of six months. The first officially recognised creation of the dukedom was in the Peerage of England in 1664, when King Charles II granted the title to his next eldest surviving nephew James Stuart, the infant second son of the Duke of York, who died early in 1667 at the age of three, when the title again became extinct. The title was then granted later that year by King Charles II to his next eldest surviving nephew Edgar Stuart, the third son of the Duke of York, who also died in infancy, in 1671 at the age of three, when the title became extinct the third time. The Duke of York's fourth son Charles (his eldest son by his second wife) was also styled Duke of Cambridge in 1677, but died when about a month old, not having lived long enough to be formally created duke. The title was recreated by Queen Anne in 1706 who granted it to George Augustus (later King George II), son of the Elector of Hanover (later King George I), her distant cousin (both being descended from King James I). When the title was created George Augustus was third in line to the throne, after his grandmother Sophia and his father. When he ascended to the throne as King George II in 1727, the dukedom merged with the Crown. The title was again recreated in
