Ричард Корнуольский: Король римлян и английский принц XIII века.

13th century English King of the Romans and Earl of Cornwall
the philosopher

Richard (5 January 1209 – 2 April 1272) was an English prince who was King of the Romans from 1257 until his death in 1272. He was the second son of John, King of England, and Isabella, Countess of Angoulême. Richard was nominal Count of Poitou from 1225 to 1243, and he also held the title Earl of Cornwall since 1225. He was one of the wealthiest men in Europe and joined the Barons' Crusade, where he achieved success as a negotiator for the release of prisoners and assisted with the building of the citadel in Ascalon.

He was born 5 January 1209 at Winchester Castle, the second son of John, King of England, and Isabella, Countess of Angoulême. He was made High Sheriff of Berkshire at age eight, was styled Count of Poitou from 1225 and in the same year, at the age of sixteen, his brother King Henry III gave him Cornwall as a birthday present, making him High Sheriff of Cornwall. Richard's revenues from Cornwall helped make him one of the wealthiest men in Europe. Though he campaigned on King Henry's behalf in Poitou and Brittany, and served as regent three times, relations were often strained between the brothers in the early years of Henry's reign, once Henry took rule for himself. Richard rebelled against him three times and had to be bought off with lavish gifts. In 1225, Richard traded with Gervase de Tintagel, swapping the land of Merthen (originally part of the manor of Winnianton) for Tintagel Castle. It has been suggested that a castle was built on the site by Richard in 1233 to establish a connection with the Arthurian legends that were associated by Geoffrey of Monmouth with the area. Richard hoped that, in this way, he could gain the Cornish people's trust. The castle itself held no real strategic value. The dating to the period of Richard has superseded Ralegh Radford's interpretation which attributed the earliest elements of the castle to Earl Reginald de Dunstanville and later elements to Earl Richard. Sidney Toy, however, has suggested an earlier period of construction for the castle.

In March 1231, he married Isabel Marshal, the wealthy widow of the Earl of Gloucester, much to the displeasure of his brother King Henry, who feared the Marshal family because they were rich, influential, and often opposed to him, as did Richard by this point. The joining of Richard to the Marshal family increased the power behind these rebellions, and the potential risk for Henry. Richard became stepfather to Isabel's six children from her first husband. In that same year he acquired his main residence, Wallingford Castle in Berkshire (now Oxfordshire), and spent much money on developing it. He had other favoured properties at Marlow and Cippenham and was a notable lord of the manor at Earls Risborough, all in Buckinghamshire. Isabel and Richard had four children, of whom only their son, Henry of Almain, survived to adulthood. Richard opposed Simon de Montfort and rose in rebellion in 1238 to protest against the marriage of his sister, Eleanor, to Simon. Once again he was placated with rich gifts. When Isabel was on her deathbed in 1240, she asked to be buried next to her first husband at Tewkesbury, but Richard had her interred at Beaulieu Abbey instead. As a pious gesture, however, he sent her heart to Tewkesbury.

Later that year, Richard departed for the Holy Land, leading the second host of crusaders to arrive during the Barons' Crusade. He did not fight any battles but managed to negotiate for the release of prisoners (most notably Amaury de Montfort) and the burials of crusaders killed at a battle in Gaza in November 1239. He also refortified Ascalon, which had been demolished by Saladin. On his return from the Holy Land, Richard visited his sister Isabella, the empress of Frederick II. After the birth of Prince Edward in 1239, provisions were made in case of the king's death, which favoured the Queen and her Savoyard relatives and excluded Richard. To keep him from becoming discontented King Henry and Queen Eleanor brought up the idea of a marriage with Eleanor's sister Sanchia shortly after his return on 28 January 1242. On his journey to the Holy Land, Richard had met Sanchia in Provence, where he was warmly welcomed by her father Raymond Berenger IV. Richard and Sanchia were married at Westminster in November 1243. Marriage to Sanchia had the advantage of tying Richard closely to the royal couple and their interests. Eleanor and Sanchia's youngest sister Beatrice married Charles I of Naples, while their oldest sister Margaret had married Louis IX of France. The marriages of the kings of France and England and their two brothers to the four sisters from Provence improved the relationship between the two countries that led to the Treaty of Paris in 1259.

Richard was appointed count of Poitou some time before August 1225. However, Richard's claims to Gascony and Poitou were never more than nominal, and in 1241, King Louis IX of France invested his own brother Alphonse with Poitou. Moreover, Richard and Henry's mother, Isabella of Angoulême, claimed to have been insulted by the French queen. They were encouraged to recover Poitou by their stepfather, Hugh X of Lusignan, but the expedition turned into a military fiasco after Lusignan betrayed them. Richard conceded Poitou around December 1243. Pope Innocent IV offered Richard the crown of Sicily, but according to Matthew Paris, he responded to the extortionate price by saying, "You might as well say, 'I will sell or give you the moon, rise up and take it'". Instead, his brother King Henry attempted to purchase the kingdom for his own son Edmund.

He founded Burnham Abbey in Buckinghamshire in 1263, and the de, Aachen in 1266. He joined King Henry in fighting against Simon de Montfort's rebels in the Second Barons' War (1264–1267). After the shattering royalist defeat at the Battle of Lewes, Richard took refuge in a windmill, was discovered, and was imprisoned until September 1265. Richard bought the feudal barony of Trematon in 1270. In March 1271 Richard's son and heir Henry of Almain was murdered in Viterbo at the Church of San Silvestro by Guy and Simon de Montfort the Younger in revenge for their father and brother Henry de Montfort being killed at the Battle of Evesham. Simon and Guy were Richard's nephews and sources say that Richard did not recover from the shock. In December 1271, he had a stroke. His right side was paralysed and he lost the ability to speak. On 2 April 1272, Richard died at Berkhamsted Castle in Hertfordshire. He was buried next to his second wife Sanchia of Provence and Henry of Almain, his son by his first wife, at Hailes Abbey, which he had founded. After his death, a power struggle ensued in Germany, which only ended in 1273 with the emergence of Rudolph I of Habsburg, the first scion of a long lasting noble family to rule the empire. In Cornwall, Richard was succeeded by Edmund, son of his second wife Sanchia.

Richard married first, on 30 March 1231 at Fawley, Buckinghamshire, to Isabel Marshal (d.1240) was the daughter of William Marshal, 1st Earl of Pembroke, by his wife Isabel de Clare, who in turn was daughter of Sir Richard "Strongbow" de Clare and Aoife MacMurrough. Isabel Marshal died on 17 January 1240 while giving birth at Berkhamsted Castle and was buried at Beaulieu Abbey. By Isabel Marshal he had four children, of whom only one reached adulthood:
John of Cornwall (31 January 1232 – 22 September 1232), born and died at Marlow, Buckinghamshire, buried at Reading Abbey. Isabel of Cornwall (c. 9 September 1233 – 6 October 1234), born and died at Marlow, Buckinghamshire, buried at Reading Abbey. Henry of Cornwall (2 November 1235 – 13 March 1271). Known as "Henry of Almain" (Germany). He was buried at Hailes Abbey in Gloucestershire. He had no children. Nicholas of Cornwall (b. & d. 17 January 1240 at Berkhamsted Castle), died shortly after birth; buried at Beaulieu Abbey with his mother.
