Jewish quota was a type of racial quota stipulating a certain set percentage that limited the number of Jews in various establishments. In particular, in 19th and 20th centuries some countries had Jewish quotas for higher education, a special case of Numerus clausus. Jews who wanted an education used various ways to overcome this discrimination: bribing the authorities, changing their religion, or traveling to countries without such limitations. In Hungary, for example, 5,000 Jewish youngsters (including Edward Teller) left the country after the introduction of Numerus Clausus.
