Given his very full education, Caesar was clearly a man of some erudition, though his distinguished father, Sir Julius, undoubtedly used his position as a senior lawyer and government minister to advance the young man’s career. In 1605 the king was prevailed upon to nominate Caesar for a fellowship at All Soul’s, Oxford, though the college apparently took over a year to comply with the request.
Caesar probably owed his election at Weymouth in 1614 to an intervention by his father, who certainly corresponded with the borough at the time of its 1610 by-elections.
Caesar enjoyed a successful career in the fields of ecclesiastical and maritime law, his progress smoothed not just by his father’s patronage but also by his own personality. In 1618 the newsletter writer John Chamberlain recorded a visit by ‘courteous Sir Charles Caesar’ to Bishop Lancelot Andrewes, while two years later the judge Sir John Davies* praised his ‘discretion and sweetness of manners’ during the summer assizes.
Under pressure from Laud, Caesar lent the king £2,000 in 1640 towards the costs of the Bishops’ Wars, apparently employing money assigned to charitable purposes by his uncle, the dean, though these bequests were subsequently honoured.
