By the fifteenth century the Greville family had settled in Warwickshire, where they acquired substantial estates. In 1605 Fulke Greville†, who was created Baron Brooke by James I, acquired the family’s principal residence of Warwick Castle.
Brooke inherited a considerable estate. A settlement of 1667 conveying his lands into the hands of trustees cited property in Warwickshire, Northamptonshire, Gloucestershire, Staffordshire and several other counties as well as lands in the City of London and Hackney.
The months leading up to the Restoration found Brooke working closely with his Warwickshire neighbours, Edward Conway, 3rd Viscount (later earl of) Conway, and Basil Feilding, 2nd earl of Denbigh, at the head of the county militia committee.
In spite of his considerable local political influence, Brooke was less active as a member of the House. Having taken his seat on 30 Apr. 1660, he attended approximately 53 per cent of all sitting days of the first session of the Convention. On 1 May he was named to the committee considering the letter of thanks to be sent to the king and the following day he was named to three further committees, including that for settling the militia. On 3 May Brooke was nominated one of those peers to present the House’s answer to the king.
In the autumn of 1660 Brooke was dropped as a deputy lieutenant in Warwickshire by the new lord lieutenant, James Compton, 3rd earl of Northampton, but in recognition of his part in bringing about the king’s return he was appointed lord lieutenant of Staffordshire instead.
Brooke was successful in overseeing uncontested elections in Staffordshire for the new Parliament.
Brooke’s attendance of the House fell dramatically in the second session of February 1663 during which he was present on just eight sitting days (nine per cent of the whole). Absent for the whole of May and June he rallied to resume his seat for two days in July, his return presumably owing to interest in the outcome of the attempted impeachment of Clarendon, by George Digby, 2nd earl of Bristol. Brooke’s indifferent attendance in the House may again have been owing to concentration on his local interests as he was complimented by Sir Henry Bennet, (later earl of Arlington) for his actions in Staffordshire during the summer of 1663.
Although assiduous in overseeing his lieutenancy, Brooke continued half-heartedly in his attendance of Parliament. Besides responsibilities in his locality his frequent absences from the House may also have owed something to his partiality for gambling. On one occasion, ‘led on by cunning and companioned by fortune’, he was said to have won an astonishing £4,800 in a single night.
Brooke failed to attend a single day of the brief session of July 1667 but he rallied a little to attend ten days of the eighth session (1667-9), just under nine per cent of the whole. Poor health may well have been the reason for his failure to attend on this occasion as it was reported in September 1668 that having been given over, he was now believed to be on the road to recovery.
Brooke was involved in a quarrel with Sir William Bromley in Warwick in the summer of 1671. The fracas appears to have been occasioned by the excesses of excise officers in Warwick and Coventry. The dispute was swiftly resolved but not without an exchange of blows.
Brooke returned to the House a month into the new session on 11 Mar. 1673 after which he was present on 16 occasions, though he was again named to only one committee. He sat for the last time on 28 Mar. 1673. Sickness again seems to have been the cause of his failure to attend and premature reports of Brooke’s demise spread in July 1674.
