In 1661 he was appointed High Sheriff of Yorkshire. He served as a member of Parliament for York (1665-73), Joint Commissioner of Public Accounts (1667); Joint Treasurer of the Navy (1668-71), and Treasurer of the Navy (1671-73). In 1673 he was appointed to the office of Lord High Treasurer. A year later, he was created Earl of Danby.
A staunch royalist, he was also a fervent Anglican and thus opposed to alliance with France. He ended (1674) England's participation in the third Dutch War and arranged (1677) the marriage of Princess Mary to the Dutch William of Orange.  However, while telling Parliament that he was raising money for war with France, he was at the same time negotiating reluctantly at Charles II's behest for a French alliance (1677). Impeached in 1678 for "treasonable communications with the French, tyrannical rule, favouring the popish party and wasting the king's revenue" he was imprisoned (1679) in the Tower of London and refused bail by the House of Commons. He resigned from his office as Lord Treasurer in March 1679.
Danby remained in the Tower for five years, during which time he made unremitting efforts to secure his freedom, appealing to both the king and Parliament. He finally was released on bail in 1684. The order of impeachment against him was annulled a year later. In subsequent years, Danby took an active part in opposition to the government. He was one of the seven noblemen to sign an invitation to Prince William of Orange in 1688. After the Revolution, he served as the Lord President of the Council (1688-99). He was disliked by many of his fellow courtiers, one of whom described the earl as "a thin, ill-natured ghost that haunts the king". In 1689 he was created Marquis of Carmarthen and in 1694 he became Duke of Leeds. He served as the Lord Lieutenant of the West Riding (1674-79, 1689-99), the East Riding (1691-99), and of the North Riding (1692-99).  He died on July 26, 1712 at the age of 81 and was buried at Harthill, in Yorkshire.
