Earl of Chester in the context of Acts of Union, 1707

Chester Terrace is one of the neo-classical terraces in Regent's Park, London. The terrace has the longest unbroken facade in Regent's Park, of about 280 metres (920 ft). It takes its name from one of the titles of George IV before he became king, Earl of Chester. It now lies within the London Borough of Camden.

As with Cornwall Terrace and York Terrace, the architectural plans were made by John Nash but subsequently altered almost beyond recognition by Decimus Burton, who was responsible for the existing design, built by his father James Burton in 1825. Nash was so dissatisfied with Decimus's design that he sought the demolition and complete rebuilding of the Terrace, but in vain. It is a Grade I listed building.

Earl of Mercia was a title in the late Anglo-Saxon, Anglo-Danish, and early Anglo-Norman period in England. During this period the earldom covered the lands of the old Kingdom of Mercia in the English Midlands.First governed by ealdormen under the kings of Wessex in the 10th century, it became an earldom in the Anglo-Danish period.During the time of King Edward the earldom was held by Leofric and his family, who were political rivals to the House of Godwine. Following the Conquest in 1066 Edwin was confirmed as earl by King William. However he was implicated in the rebellion of 1071 and was dispossessed.Following the death of Edwin the earldom was broken up, the power and regional jurisdiction of the earl passing to the newly formed earldoms of Chester and later Shrewsbury.

Arthur, Prince of Wales (19/20 September 1486 – 2 April 1502) was the eldest son of King Henry VII of England and Elizabeth of York, and an older brother to the future King Henry VIII. He was Duke of Cornwall from birth, and he was created Prince of Wales and Earl of Chester in 1489. As the heir apparent of his father, Arthur was viewed by contemporaries as the great hope of the newly established House of Tudor. His mother was the daughter of the Yorkist king, Edward IV, and his birth cemented the union between the House of Lancaster and the House of York.

Plans for Arthur's marriage began before his third birthday. At the age of eleven, he was formally betrothed to Catherine of Aragon, a daughter of the powerful Catholic Monarchs in Spain, in an effort to forge an Anglo-Spanish alliance against France and Scotland. Arthur was well educated and was in good health for the majority of his life. Soon after his marriage to Catherine in 1501, the couple took up residence at Ludlow Castle in Shropshire, where Arthur died six months later, possibly from the sweating sickness, which Catherine survived. Catherine later firmly stated that the marriage had not been consummated.
