Earl of Chester

The Earldom of Chester (Welsh: Iarll Caer) was one of the most powerful earldoms in medieval England, extending principally over the counties of Cheshire and Flintshire. Since 1301 the title has generally been granted to heirs-apparent to the English throne, and from the late 14th century it has been given only in conjunction with that of Prince of Wales.

The County of Cheshire was held by the powerful Earls (or "Counts" from the Norman-French) of Chester from the late eleventh century, and they held land all over England, comprising 'the honour of Chester'. By the late twelfth century (if not earlier) the earls had established a position of power as quasi-princely rulers of Cheshire that led to the later establishment of the County Palatine of Chester and Flint.

The earldom passed to the Crown by escheat in 1237 on the death of John the Scot, Earl of Huntingdon, seventh and last of the Earls. William III de Forz, 4th Earl of Albemarle, claimed the earldom as husband of Christina, the senior co-heir, but the king persuaded them to quitclaim their rights in 1241 in exchange for modest lands elsewhere. The other co-heiresses did likewise. It was annexed to the Crown in 1246. King Henry III then passed the Lordship of Chester, but not the title of Earl, to his son, the Lord Edward, in 1254; as King Edward I, this son in turn conferred the title and lands of the Earldom on his son, Edward, the first English Prince of Wales. By that time, the Earldom of Chester consisted of two counties: Cheshire and Flintshire.

The establishment of royal control of the Earldom of Chester made possible King Edward I's conquest of north Wales, and Chester played a vital part as a supply base during the Welsh Wars (1275–84), so the separate organisation of a county palatine was preserved. This continued until the time of King Henry VIII. Since 1301, the Earldom of Chester has always been conferred on the Princes of Wales.
