Context paragraphs:
paragraph_text: While working at Capital Radio, Sophie met Prince Edward, the youngest son of the Queen and the Duke of Edinburgh, for the first time in 1987 when he was dating her friend. She met Prince Edward again at a charity event in 1993, and the two began their relationship soon afterwards. Their engagement was announced on 6 January 1999. Edward proposed to Sophie with an engagement ring featuring a two-carat oval diamond flanked by two heart-shaped gemstones set in 18-carat white gold. The ring was made by Asprey and Garrard (now Garrard & Co) and is worth an estimated £105,000. Sophie, who was reportedly close to the Queen from the beginning of her relationship with Edward, was allowed to use the royal apartments at Buckingham Palace prior to her engagement. The wedding took place on 19 June of the same year at St George's Chapel at Windsor Castle, a break from the weddings of Edward's older siblings, which were large, formal events at Westminster Abbey or St Paul's Cathedral. On the day of their marriage, Prince Edward was created a hereditary peer as Earl of Wessex with the subsidiary title of Viscount Severn (derived from the Welsh roots of the Countess's family). It is understood that he will be elevated as Duke of Edinburgh when that title reverts to the Crown. The couple spent their honeymoon at Balmoral Castle. Following their union, the Earl and Countess moved to Bagshot Park, their home in Surrey. While their private residence is Bagshot Park, their office and official London residence is based at Buckingham Palace. Due to renovations at Buckingham Palace in 2018, the couple temporarily moved their offices to St James's Palace.

paragraph_text: When finally Edward the Confessor returned from his father's refuge in 1041, at the invitation of his half-brother Harthacnut, he brought with him a Norman-educated mind. He also brought many Norman counsellors and fighters, some of whom established an English cavalry force. This concept never really took root, but it is a typical example of the attitudes of Edward. He appointed Robert of Jumièges archbishop of Canterbury and made Ralph the Timid earl of Hereford. He invited his brother-in-law Eustace II, Count of Boulogne to his court in 1051, an event which resulted in the greatest of early conflicts between Saxon and Norman and ultimately resulted in the exile of Earl Godwin of Wessex.

paragraph_text: Edmund of Woodstock, 1st Earl of Kent (5 August 130119 March 1330) was the sixth son of Edward I of England, and a younger half-brother of Edward II. Edward I had intended to make substantial grants of land to Edmund, but when the king died in 1307, Edward II failed to follow through on his father's intentions, much due to his favouritism towards Piers Gaveston. Edmund still remained loyal to his brother, and in 1321 he was created Earl of Kent. He played an important part in Edward's administration, acting both as diplomat and military commander, and in 1321–22 helped suppress a rebellion against the King.

paragraph_text: The wedding dress of Princess Elizabeth was worn by the future Queen Elizabeth II at her wedding to Philip Mountbatten, Duke of Edinburgh on 20 November 1947 in Westminster Abbey.
