In his youth he accompanied his father to the marriage of
Princess Mary (sister of King Henry VIII), to King
Louis XII of France. He returned to France during the 1520s, fighting with distinction around
Calais. In 1517 or before 1526 he married
Anne Bray. In July 1523, after the taking or
Morlaix, he was invested as a
Knight by the
Earl of Surrey and succeeded in his father's title in November 1529. In 1536 he was one of the 27 peers for the trial of his second cousin Queen
Anne Boleyn. After the
dissolution of the monasteries he received large grants of land. In July 1523 after the taking of
Morlaix, he was invested as a
Knight by
Thomas Howard, Earl of Surrey and succeeded to his father's title in November 1529. In 1536 he was one of the 27 peers at the trial of his second cousin Queen
Anne Boleyn. After the
Dissolution of the Monasteries he acquired much former monastic property. At home in
Kent, he fulfilled his feudal duties, serving as
Justice of the Peace for the county. In 1544, he occupied a high position in the
English army that invaded
Scotland; later that year, he was appointed commanding officer of English-controlled
Calais, a personal possession of the king. In 1546 he became
Lieutenant-General against the Scots, under the
Earl of Hertford. He was made a
Knight of the Garter on 24 April 1549. Brooke's family were dogged by scandal. His sister,
Elizabeth Brooke, was married to Sir
Sir Thomas Wyatt but lived openly in adultery with another man. Allegedly she attracted the attention of
Henry VIII in 1542, and
Eustace Chapuys, the Imperial ambassador, thought that had she tried she could have become Henry's sixth wife. His daughter,
Elisabeth Brooke, Marchioness of Northampton, was also prone to scandal as from 1543 she had lived with her future husband
William Parr, 1st Marquess of Northampton whilst he was separated from his wife
Anne Bourchier, 7th Baroness Bourchier. They eventually married during the reign of
Edward VI, but this was declared invalid by
Mary I. In the reign of
Elizabeth I, their marriage was finally confirmed as valid. He resigned his post in 1550 and became a member of the
Privy Council of
Edward VI on 23 May. After Edward's death, Brooke supported the attempt by
John Dudley, 1st Duke of Northumberland to place his daughter-in-law
Lady Jane Grey on the throne. He was pardoned by Queen
Mary I, but subsequently fell under suspicion again. His nephew, Sir
Thomas Wyatt the younger was the leader of
Wyatt's Rebellion, a Protestant rebellion which brought suspicion on the whole family. Brooke's daughter, Elizabeth Brooke, is thought to have been the instigator of the plot to place
Lady Jane Grey on the throne instead of Mary I. During
Wyatt's rebellion, Wyatt besieged and took Cobham in the latter's home,
Cooling Castle; Brooke claimed to have resisted, but after the rebellion failed, he was accused of complicity in the rebellion and imprisoned in the
Tower of London for a brief period, but was released. The next year, at the start of the
Roman Catholic Queen's formal reconciliation with the
Holy See, he was assigned to welcome to England the
papal legate Cardinal Pole, who went on to be responsible for many Protestant martyrdoms in England. The entertainment is recorded as having taken place at Cooling Castle in 1555. After his release, Brooke limited himself to local affairs in Kent. He died in 1558, closely followed by his wife, Anne Bray. An inquest post mortem was held for his on 20 January 1558/1559 and his
will, dated 13 January 1557/1558, was probated on 6 December 1560. He was succeeded in the barony by his son,
William. ==Marriage and issue==
