Called to the bar in 1668, Jeffreys rose to prominence through vigorous activity and astute cultivation of business and political contacts. As recorder of London and later Chief Justice of Chester, his royalist sympathies were apparent in his decisions and opinions, and Charles II made him a baronet in 1681. In 1683 he was appointed to the king's bench, where he presided over some of the proceedings consequent on the Rye House plot to assassinate Charles II as well as a large number of prosecutions for seditious libel.

Minimally successful in the legal profession for which he was trained, Jeffrey found his calling in 1802 when he and a few of his friends founded the Edinburgh Review, with Jeffrey taking over as editor in 1803.
