After nearly two years spent in the new United States, John Singleton Copley, the younger, returned to what had now become the settled home of the Copley family. He commenced a long course of study and systematic preparation for a life which was to become of the most distinguished, among the most famous men of the first half of the 19th century. Called to the bar in 1804 he, with no other influence than that of his own commanding talents, soon ranked among the leading men of his profession and that at a time when an unusually large number of great advocates were at the English bar. But it was not at the bar only, or when on the bench at the head of the judiciary of England that this son of Boston distinguished himself. In both houses of Parliament, as Copley or Lyndhurst, he was an acknowledged leader of men. Copley took his seat in the House of Commons as member for Yarmouth in the Isle of Wight, in March 1818, and until his removal to the House of Lords, nine years later, sat continuously as a member. Meanwhile promotion, professionally and politically, was constantly growing. In 1819, he was made a king's sergeant (at large) and chief justice of Chester. In June of the same year he was appointed Solicitor General (with knighthood), five years later became Attorney General. In 1826 he succeeded Lord Gifford as Master of the Rolls, a high judicial office, which at that time and for many years after did not compel the vacating of a seat in Parliament. The town Council of Bristol unanimously elected him in the same year Recorder of that city. In April 1827 in his 55th year on the retirement of Lord Chancellor Eldon, the ambition of his life was realized. The great prize of the legal profession was offered to him by the express desire of the king and with it of course a peerage, Sir John Singleton Copley became Baron Lyndhurst of Lyndhurst in the County of Hampshire and, for nearly forty years thereafter remained to adorn the House of Lords by his high talents, his noble character, and his fervid eloquence.
