[[File:Frederick Lewis, Prince of Wales by Philip Mercier.jpg|thumb|upright|[[Frederick, Prince of Wales]] (1707–1751) was the first Duke of Edinburgh, from 1726 until his death.]]
The title was first created in the [[Peerage of Great Britain]] on 26 July 1726 by King [[George I of Great Britain|George I]], who bestowed it on his grandson [[Frederick, Prince of Wales|Prince Frederick]], who subsequently became [[Prince of Wales]] in 1728. The [[subsidiary titles]] of the dukedom were Marquess of the Isle of Ely,<ref name=TCP>{{cite book |first = G.

In later editions of the ''[[London Gazette]]'' the Duke is referred to as the Marquess of the [[Isle of Ely]].<ref>{{London Gazette |issue=6741 |date=4 January 1728 |page=2 }}</ref><ref>{{London Gazette |issue=9050 |date=16 April 1751 |page=1 }}</ref> Upon Frederick's death, the titles were inherited by his son Prince George.
