Question: Richard le Scrope, 1st Baron Scrope of Bolton served Richard II of England who was also known by what name?
Context: Earl of Sunderland is a title that has been created twice in the Peerage of England.  The first creation came in 1627 in favour of Emanuel Scrope, 12th Baron Scrope of Bolton.  The earldom became extinct on his death in 1630 while the barony became either extinct or dormant (see Baron Scrope of Bolton for more information on this title).  The second creation came in 1643 in favour of the Royalist soldier Henry Spencer, 3rd Baron Spencer of Wormleighton.  The Spencer family descended from Sir John Spencer (d. 1522) who acquired the Wormleighton estate in Warwickshire and the Althorp estate in Northamptonshire.  His grandson Sir John Spencer (d. 1586) was a Knight of the Shire for Northamptonshire.  The latter's grandson Sir Robert Spencer represented Brackley in Parliament in the late 16th century.  In 1603 Sir Robert was raised to the Peerage of England as Baron Spencer of Wormleighton.  He was succeeded by his eldest surviving son, William, the second Baron.  He had previously represented Northamptonshire in Parliament.  His eldest son was the aforementioned third Baron.  In July 1643 he was created Earl of Sunderland in the Peerage of England.  Lord Sunderland was killed at the Battle of Newbury in September of the same year.  He was succeeded by his two-year-old only son, Robert, the second Earl.  He later gained great distinction as a statesman and notably served four times as Secretary of State for the Southern Department. Richard le Scrope, 1st Baron Scrope of Bolton ( 1327 – 1403) was an English soldier and courtier, serving Richard II of England.  He also fought under the Black Prince at the Battle of Crecy in 1346. Baron Scrope of Masham is an abeyant title in the Peerage of England.  It was created on 25 November 1350 as a barony by writ for Henry le Scrope, son of Geoffrey le Scrope and first cousin of Richard le Scrope, 1st Baron Scrope of Bolton.  Richard le Scrope, a younger son of the 1st Baron, was Archbishop of York and executed for his role in the Percy revolt of 1405. William le Scrope, 1st Earl of Wiltshire, King of Mann (1350–1399) was a close supporter of King Richard II of England.  He was a second son of Richard le Scrope, 1st Baron Scrope of Bolton. Thomas le Scrope, 10th Baron Scrope of Bolton (1567 – 2 September 1609) was the son of Henry le Scrope, 9th Baron Scrope of Bolton and Margaret Howard, daughter of Henry Howard, Earl of Surrey. John le Scrope, 8th Baron Scrope of Bolton (c. 1510 – 22 June 1549) was the son of Henry le Scrope, 7th Baron Scrope of Bolton and Mabel Dacre. Henry le Scrope, 1st Baron Scrope of Masham ("c." 1312 – 31 July 1392) was an English soldier and administrator. Stephen Scrope, 2nd Baron Scrope of Masham and Upsale (1345-1406) was the second surviving son of Henry Scrope, 1st Baron Scrope of Masham.  Stephen Scrope had a brother, John, and a sister Joan, who married Henry, Lord Fitzhugh. Richard II (6 January 1367 – c. 14 February 1400), also known as Richard of Bordeaux, was King of England from 1377 until he was deposed on 30 September 1399.  Richard, a son of Edward, the Black Prince, was born in Bordeaux during the reign of his grandfather, Edward III.  His father was Prince of Aquitaine.  Richard was the younger brother of Edward of Angoulême, upon whose death Richard, at three years of age, became second in line to the throne after his father.  Upon the death of Richard's father prior to the death of Edward III, Richard, by primogeniture, became the heir apparent to the throne.  With Edward III's death the following year, Richard succeeded to the throne at the age of ten. The title Baron Scrope of Bolton was created in the Peerage of England for Sir Richard le Scrope as a barony by writ on 8 January 1371.  It became dormant on the death of the 11th Baron (1st Earl of Sunderland) in 1630 without legitimate issue.
