King Richard I of England gave the city of Portsmouth (pictured) its first royal charter.

Richard I, known as Richard the Lionheart or Richard Cœur de Lion because of his reputation as a great military leader and warrior, was King of England from 1189 until his death in 1199. He also ruled as Duke of Normandy, Aquitaine, and Gascony; Lord of Cyprus; Count of Poitiers, Anjou, Maine, and Nantes; and was overlord of Brittany at various times during the same period. He was the third of five sons of Henry II of England and Eleanor of Aquitaine and was therefore not expected to become king, but his two elder brothers predeceased their father.

Portsmouth is a port city and unitary authority in Hampshire, England. Most of Portsmouth is located on Portsea Island, off the south coast of England in the Solent, making Portsmouth the only city in England not located primarily on the mainland. The city is located 22 miles (35 km) south-east of Southampton, 50 miles (80 km) west of Brighton and Hove and 74 miles (119 km) south-west of London. With a population last recorded at 208,100, it is the most densely populated city in the United Kingdom. Portsmouth forms part of the South Hampshire urban area with Gosport, Fareham, Havant, Eastleigh and Southampton.

A royal charter is a formal grant issued by a monarch under royal prerogative as letters patent. Historically, they have been used to promulgate public laws, the most famous example being the English Magna Carta of 1215, but since the 14th century have only been used in place of private acts to grant a right or power to an individual or a body corporate. They were, and are still, used to establish significant organisations such as boroughs, universities and learned societies, and were historically used to establish companies.
