Granville's literary output was reserved for his earlier years: throughout the late 1680s and the 1690s he wrote non-dramatic, complimentary verse modelled on that of Edmund Waller in addition to numerous plays. The 1700s saw multiple collections of his poems and plays, but he seemed to focus mostly on his career as a prominent tory/Jacobite politician and statesman under Queen Anne, spending lavishly on elections. With the accession of George I, he lost all of his offices and was charged with high treason from 1715-1717, but never brought to trial. During the South Sea Bubble he purchased £20,000 worth of South Sea stock, losing £10,000 when the Bubble burst. He moved to Paris in 1720 where he headed Jacobite conspiracies, writing most of the French Jacobite propaganda around this time. Under financial distress due to his wife's extravagance and accumulating debts, Granville was lent 15,000 livres out of James's funds. Granville returned to England in 1725 after the failed Atterbury plot in the hopes of reconciling himself with the Hanoverian government.
