Throughout his life, Glover was actively involved in political affairs, often acting as a spokesman for merchants and furthering the 'patriot' whig agenda. His literary works -- poems and plays -- often spoke to such content. His poem Leonidas received much acclaim from those of like-minded politics, including from Swift and Lyttleton. He also wrote political memoirs. Apparently, he made a lot of money out of the subscription to the government loan of 1763. He died considerably wealthy, leaving over £11,000 to his son Richard, an income of £150 to his second wife Eleanor, and over £8000 to his 'natural daughter' Mary.
