What jobs did the Jews in England do?

Answer 1

First of all, the Jews were expelled from England (after a number of anti-Jewish massacres), for several hundred years. While they were in Norman England, they were mostly commanded to limit themselves to moneylending, and there were a few Jewish doctors as well. They were banned from most trades. Under King Henry, Jews were allowed to buy and sell goods (1100-1135). Detailed information may be had on this linked page.

When Jews returned to England (1600s-1800s), they functioned as merchants and traders, and Nathan Mayer Rothschild founded a bank (1798). Later, as the British gradually relaxed their anti-Semitic decrees and attitude (1800s), the Jews were able to diversify their occupations.

Answer 2

All types of jobs and the answer cannot be more definite as Britain did not demand people to register according to religion unlike nazi Germany.
