from high office under Charles II. On the accession of the King’s brother, James in 1685, Herbert became one of the new king’s chief ministers, and was again advanced in the peerage becoming Marquess of Powis in 1687, but fell at the Glorious Revolution of 1688 and followed James into exile in France. William III granted the castle to his nephew, William Nassau de Zuylestein, 1st Earl of Rochford. Herbert died, still in exile, in 1696. Despite their 30-year exile, the Herberts continued developments at the castle and even to live there on an irregular basis, the Baroque water garden below the castle being completed at this time. Their fortunes were also materially improved by the discovery of a lucrative lead mine on their Welsh estates. The second Marquess, also William, was reinstated in 1722. On the death of his son, the third Marquess in 1748, the marquessate became extinct, while the castle and estates passed to a relative Henry Herbert (), of Oakly Park in Shropshire, who was made 1st Earl of Powis (of the second creation) by George II. Herbert married Barbara, the fifteen-year old granddaughter of the 2nd Marquess, in 1751. Their eldest son, George Herbert (1755–1801), died unmarried and the earldom of the second creation became extinct. Powis was much neglected during his tenure. John Byng, 5th Viscount Torrington, a diarist and traveller who chronicled his journeys into Wales in the 1780s and 1790s, described the castle in 1784, "In the gardens not even the fruit is attended to; the balustrades and terraces are falling down, and the horses graze on the parterres!!!" The castle itself was in no better condition, a visitor in 1774 describing it as "in Neglect and Ruin". Nonetheless, the potential of the site was recognised. George Lyttelton, the politician, poet and essayist, recorded his impressions in 1756, "About £3,000 laid out upon Powis Castle would make it the most august place in the Kingdom." The Clives and Herberts: 1801–1952 In 1784, Henry Herbert's daughter, Henrietta, married Edward Clive (1754–1839), the eldest son of Clive of India. Clive had followed his father to India, and served as Governor of Madras. Henrietta's brother died in 1801, whereupon the title lapsed; in 1804, her husband was created first Earl of Powis (of the third creation). The Clive fortune paid for long overdue repairs to the castle, which were carried out by Sir Robert Smirke.
