Marshal of England bishop of Lichfield
He was the second son of Nicholas of Seagrave, first Baron Seagrave and a leading supporter of Simon de Montfort in his struggle with King Henry III.
Nicholas Seagrave was first summoned to Parliament in 1295 and continued to be summoned until his death. In 1298 he fought in the vanguard at the Battle of Falkirk. In 1300 he was present at the siege of Caerlaverock in the retinue of Henry de Bohun, 1st Earl of Hereford, and in 1301 he sealed the barons" remonstrances to the pope as "Nicholas de Seagrave, lord of Stow".
In the Scottish campaign of 1303-1304 he became involved in another dispute, and when he was refused trial by combat he deserted the army to flee to France.
On his return in 1305 he was apparently sentenced to death, but soon pardoned and restored to favour by King Edward I.
He was one of Edward II"s strongest supporters at the start of his reign, and in 1308 he was appointed Lord Marshal. However, he was an adherent of Thomas, 2nd Earl of Lancaster, who became a leader of the opposition to the king.
This made Seagrave"s position at court increasingly untenable, and he was replaced in 1316. He died on 25 November 1321.
