William the Conqueror gave Pleshey, in the parish of
High Easter (southwest of
Braintree), to
Geoffrey de Mandeville. At Pleshey, Mandeville built his caput (centre of administration and main home) of the many villages in Essex given to him by the king. Later, his grandson, another Geoffrey, was made
Earl of Essex by
King Stephen. For a long time, Pleshey Castle was an important place in English history. Through inheritance, Pleshey Castle became the main castle of
Henry de Bohun, 1st Earl of Hereford, and his wife, Maud, sister and heiress of
William de Mandeville, Earl of Essex. From this marriage de Bohun's son Humphrey became Earl of Essex (27 Aug 1236) as well as Earl of Hereford and Hereditary Constable of England. Generations of de Bohuns resided here, with Pleshey as their
caput manor.
Humphrey de Bohun VIII (4th Earl of Hereford and 3rd of Essex (1275?-1322) on 14 Nov. 1302 married
Elizabeth, the daughter of
Edward I, King of England. Some of their children were born at Pleshey. Humphrey VIII was killed at the
Battle of Boroughbridge in 1322, rebelling against
King Edward II. In 1327, Pleshey Castle became the primary residence of Humphrey VIII's eldest surviving son,
John de Bohun, created Earl of Hereford and Essex. He died in 1336 without an heir and the castle passed to his brother,
Humphrey IX, Earl of Hereford and Essex (d. 1361). The youngest of the brothers,
William de Bohun (d. 1360), became the leading commander of the early part of the
Hundred Years War, devising the tactics that won English victories at the
Battle of Morlaix (1342), the
Battle of Crecy (1346), and the
Siege of Calais (1347), and was created Earl of Northampton. Humphrey IX never married and Pleshey was inherited in 1361 by William's son and heir,
Humphrey de Bohun X (b. 1342), last male heir of the direct line. This Humphrey inherited both his uncle's and his father's titles and became Earl of Hereford, Essex, and Northampton. His only heirs at his death on 13 January 1373 were two young daughters,
Eleanor and
Mary. Between 1361 and 1384 a group of
Augustinian friars created the de Bohun manuscripts at Pleshey Castle; eleven books, one of them a
Psalter, celebrating
Mary de Bohun's marriage to
Henry Bolingbroke, the future Henry IV, King of England. The Mary de Bohun Psalter is now in the
Fitzwilliam Museum. Mary, who died before her husband became king, was the mother of
Henry V, of Agincourt fame. The castle then passed (through the marriage of Eleanor) to
Thomas of Woodstock, Duke of Gloucester, the youngest son of
Edward III. His nephew,
Richard II, outraged by his uncle's opposition, had him arrested at Pleshey and taken to France. Two years later the
Duke of Exeter was taken to Pleshey Castle and executed for plotting against the king. Pleshey Castle is mentioned in
Shakespeare's play
Richard II, in which Thomas of Woodstock's widow asks for a visit from
Edmund of York: :Bid him – O, what? :With all good speed at Plashy visit me. :Alack, and what shall good old York there see, :But empty lodgings and unfurnished walls, :Unpeopled offices, untrodden stones? (
Richard II, Act 1, Scene 2, Lines 65–69) ==Pleshey Castle==
