Mrs. Catherine Macaulay (Sawbridge) (1731‑1791) was an English historian. A daughter of a landed proprietor of Kent, she was an advocate of republicanism, and a sympathiser with the French Revolution. She wrote a History of England from the Accession of James I to the Elevation of the House of Hanover (8 volumes, 1763‑83), which had great popularity in its day, some critics, e.g. Horace Walpole, placing it above Hume. Though a work of no real research or authority, it is in the main well written.
