Thomas Gerard, 1st Baron Gerard (c. 1564 – 15 January 1618) was a Staffordshire and Lancashire landowner and politician, a member of six English parliaments for three different constituencies. Although a prominent member of the Essex faction in the reign of Elizabeth I, he avoided involvement in the Essex Rebellion and received greater honours, including a peerage, in the reign of James I.
Thomas Gerard's parents were
Thomas Gerard was educated privately by a Thomas Taylor. It is thought his childhood was spent in the south of England, as he was described as coming from Harrow on the Hill at his admission to Caius College, Cambridge, in 1580, aged 16. He was first returned to the House of Commons of England aged only 20, as member for Lancaster.
Gerard's early political career was owed to his father's influence. Gilbert Gerard had been appointed vice-chancellor at Lancaster in 1571. The Duchy of Lancaster, merged with the Crown since 1399, had always been decisive in the choice of members of parliament for the borough, and candidates were generally friends of duchy officials, although election was formally by the mayor, bailiffs, burgesses, and citizens. In 1584, they simply sent a blank indenture or election return to Gilbert Gerard, the duchy's chief law officer, and he filled in the name of his son. Thomas was returned alongside Henry Sadler, son of Ralph Sadler, the Chancellor of the Duchy of Lancaster. Sadler had already represented Lancaster in the two previous parliaments. Both Sadler and Gerard were returned as members for Lancaster again in 1586.
