Henry Percy , 5th Earl of Northumberland Henry Algernon Percy , 5th Earl of Northumberland , KG ( 13 January 1477 – 19 May 1527 ) was an English noble who was a member of the courts of both Henry VII and Henry VIII . Biography . Henry Algernon Percy was well looked after and brought up at the court of Henry VII , while his sisters ' marriages were the object of careful negotiation . He was made K . B . 21 November 1489 , at the time when Prince Arthur was created Prince of Wales . On 28 April 1489 Henry Algernon Percy succeeded his father , Henry Percy , 4th Earl of Northumberland , as 5th Earl of Northumberland . Northumberland attended Henry VII at the conclusion of the treaty of Etaples in 1492 , and took a prominent part in the elaborate ceremony of 1494 , when Prince Henry was created K . B . In 1495 he was made a Knight of the Garter . In 1497 he served in the royal army against the Cornish rebels , and fought at the battle of Blackheath ; on 14 May 1498 he received livery of his lands , and entered into the management of his various castles and estates . How important Northumberland ' s position was can be seen from " The Northumberland Household Book " , which was edited from the manuscript in possession of the Duke of Northumberland by Thomas Percy in 1770 . It was begun in 1512 . His income was about £2 , 300 . a year , which probably does not include all that he received by way of gift . But on his various retinues of servants he spent no less than £1 , 500 . a year , and as the margin had to meet all such expenses as his journeys to the court , and as he was extraordinarily magnificent in taste , he was soon in debt . In 1500 Northumberland was at the meeting of Henry and the Archduke Philip . In 1501 he was appointed constable of Knaresborough , steward of the Lordship of Knaresborough , and master forester in the forest there . On 1 April 1502 he was a commissioner of oyer and terminer for London ; he was also constantly in the commission of the peace for various counties . Northumberland received the important appointment of warden of the east marches towards Scotland on 30 June 1503 , and one of his first duties was to escort Margaret to Scotland on her way to join James IV of Scotland , and his splendid dress and numerous servants pleased the princess . Northumberland seems to have irritated Henry VII just before the king died . He had disposed of the wardship and marriage of Elizabeth , daughter and heiress of Sir John Hastings . He was fined £10 , 000 , an amount of money quite as difficult to raise ; and it is extraordinary that he managed to pay half the money before Henry VIII came to the throne . The new king cancelled the remainder of the debt 21 March 1510 . On 4 February 1512 he was a trier of petitions from Gascony and beyond the sea . Northumberland served in the war of 1513 as a grand captain , with a very large retinue . From Calais he went to the siege of Thérouanne and in the battle of the Spurs he commanded the " showrers and forridors " , Northumberland men on light geldings . The next year he was a chief commissioner of array for various counties . As Thomas Wolsey rose , the great nobles had one by one to submit to his tyranny . Northumberland , on the advice of Will Hatty , was suspected of being too friendly with Edward Stafford , 3rd Duke of Buckingham , and so , on a charge of interfering with the king ' s prerogative about the wards , he was cast into the Fleet Prison in 1516 . Possibly he was only put there so that Wolsey might have the credit of getting him out . He was examined in the Court of the Star Chamber , and soon set free . Northumberland was friendly with George Talbot , 4th Earl of Shrewsbury , and they arranged to go on a pilgrimage this year together . Shrewsbury had been anxious to marry his daughter to a son of Buckingham , but , having disputed about money matters , the parents broke off the match ; it was now arranged , most unfortunately as it turned out , that the lady should marry Northumberland ' s son , the Lord Percy , in June 1517 Northumberland met Queen Margaret of Scotland at York to conduct her on her way home ; he undertook the duty with reluctance , doubtless from want of money , and his wife was excused attendance . In 1518 he was one of those who held lands in Calais . Wolsey in 1519 , in a letter to the king , expressed suspicions of his loyalty . But he escaped the fate of the Duke of Buckingham , and went to the Field of the Cloth of Gold , where he was a judge of the lists . The same year , 1517 , Northumberland had a grant of the honour of Holderness . He was present at Henry ' s meeting with the emperor in May 1522 , and attested the ratification of the treaty made . He seems to have been offered , but not to have accepted , the wardenship of all the marches towards Scotland in 1523 , and is said to have incurred the contempt of his tenants by his refusal . But he continued active while Henry Howard , Earl of Surrey was in chief command . In 1523 he made an inroad into Scotland , and was falsely accused by Dacre of going to war with the crosskeys of York , a royal badge , on his banner ; he cleared himself easily enough . In 1524 he was again on the border . In 1525 he had some trouble with the council of the north , of which he had been a member since 1522 ; but he cleared himself , and took part in the ceremony of the creation of Henry Fitzroy , Henry VIII ' s natural son , Earl of Nottingham . He died at Wressell on 19 May 1527 , and was buried at Beverley , where he had built a splendid shrine . Northumberland was magnificent in his tastes , and being one of the richest magnates of his day , kept a very large establishment , and was fond of building . Leland praised the devices for the library at Wressell , presumably arranged by him . He encouraged the poet John Skelton , who wrote the elegy on his father . A manuscript formerly in his possession forms British Museum Reg . Bib . 18 D ii . It consists of poems , chiefly by Lydgate . Family . Northumberland was son of Henry Percy , 4th Earl of Northumberland , by Maud , daughter of William Herbert , 1st Earl of Pembroke , of the second creation Alan Percy was his younger brother . Northumberland married Catherine Spencer ( " d " . 1542 ) , daughter of Sir Robert Spencer and Eleanor Beaufort , Countess of Ormonde . By Catherine he had three sons and two daughters :
