Caesar was 11 years old in 1614 when his father, Sir Julius, became master of the Rolls, the second highest office in Chancery, and there can be little doubt that, as a younger son, much of Caesar’s subsequent education was intended to equip him for a post in that court. Consequently, shortly after matriculating at Oxford in January 1616, he was admitted to his father’s Inn, the Inner Temple, where he was called to the bar in 1622. It is possible that he practiced as a barrister in the early part of his career as Clarendon (Edward Hyde†) was subsequently to describe him as ‘a lawyer of good name, and exceedingly beloved’.
Caesar was returned to Parliament for Bodmin in 1625 on the interest of Sir Robert Killigrew*, his stepmother’s brother-in-law.
Caesar initially failed to find a seat in the second Caroline Parliament, but was elected for Ilchester after John Selden, who had been double returned, chose to sit elsewhere. He presumably owed his election to Sir Robert Phelips*, the dominant electoral patron of the borough whose father had been Sir Julius Caesar’s predecessor as master of the Rolls. During the Parliament Caesar made no speeches, but was named to nine committees. On 22 Mar. he was among those appointed to consider the election of Sir Thomas Monck, who had been returned for Camelford while imprisoned for debt.
In 1628 Caesar acquired one of the three clerkships of the petty bag, which office was in his father’s gift as master of the Rolls. Sir Julius subsequently also tried to obtain one of the lucrative six clerks’ posts for his son. However, according to Clarendon, whose rather garbled account was written many years after the event, lord treasurer Weston (Sir Richard Weston*) blocked Robert Caesar’s appointment in favour of another candidate, who had paid him £6,000. Clarendon added that Weston promised to secure the reversion of the next vacancy for Caesar even if Sir Julius died in the interim, and wrote himself a note saying ‘remember Caesar’, which he put it in his pocket; but by the time he had found it again he had forgotten the cause and thought it was a secret warning of a plot against his life.
Although Sir Julius lived on until April 1636 he settled an estate on his son some years earlier.
Caesar died on 27 Oct. 1637, and was buried on 9 Nov. next to the communion table in St. Helen’s Bishopsgate, London, near his mother and father and his paternal grandparents.
