Politics He was nominated for
Cambridgeshire for the 1653
Barebone's Parliament. In 1659, for the
Third Protectorate Parliament, he was MP for
Yarmouth, in the
Isle of Wight. Ernestine van der Wall writes: The
Hale Commission on law reform, headed from 1652 by
Sir Matthew Hale, had Sadler as a leading lawyer, together with
William Steele and John Fountain. He was
Town Clerk of London from 3 July 1649 (elected) to 18 September 1660. He was suspended 4 September 1660, then the suspension was removed on 6 September 1660 and finally he was "declared incapable of office" on 18 September 1660.
Political thought He wrote
The Rights of the Kingdom (1649), a founding document of
British Israelism. Tudor Parfitt calls it "one of the first invented expressions of an invented Israelite genealogy for the British". This was not, however, its overt purpose. Glen Burgess calls it "an historical defence of the regicide".
Maurice Vile writes
Hartlib circle Sadler was a
philosemite, on friendly terms with
Menasseh Ben Israel. He believed that
readmission would allow for the Jews to be converted to Christianity, which would hasten the
new millennium (which he conceived as being a time of "more justice and more mercy" rather than being visited by Christ's "bodily presence"). He was also an associate of
Samuel Hartlib and
John Dury. This interest was not clearly separated from the line taken by Sadler in
The Rights of the Kingdom. ==Personal life==
