Coventry inherited an estate that, while still lucrative, was in need of serious attention. Although he did not live to see the estate restored, the policies that he initiated with his agent, Francis Taylor, ensured the continued wealth of his family.
During his short career in the House, Coventry appears to have departed from his father’s political path and to have taken a sympathetic stance to the plight of the imprisoned former lord treasurer, Thomas Osborne, earl of Danby (later duke of Leeds). A forecast drawn up by Danby estimated that if Coventry did not support his efforts to be bailed in the coming sessions he would abstain. Coventry took his seat in the House on the first day of the session held at Oxford on 21 Mar. 1681 and sat for six of its seven days. He was named to the committees for privileges and petitions and on 25 Mar. to the committee receiving information about the plot. Despite opposing Exclusion and standing against the Whigs, on the news of the death of his great-uncle, Anthony Ashley Cooper, earl of Shaftesbury, Coventry, Windsor and other relatives went into public mourning.
Coventry appears to have been a passionate follower of the turf. His enthusiasm was remarked on by his kinsman, Henry Savile‡, who commented at Newmarket in March 1683 how the young lord ‘comes little to court, his business being most amongst the jockeys.’
Coventry died in July 1687 aged just 32 of a violent fever following a long illness. Hogsdun (Hoxton) waters were said to have added dramatically to his suffering. He died intestate, leaving it to his mother to take out letters of administration.
