For centuries, before Jewish emancipation, European Jews were forced to live in ghettos where Jewish culture and religious observance were preserved. Change began in the wake of the Age of Enlightenment, when some European liberals sought to include the Jewish population in the emerging empires and nation states. The influence of the "Haskalah" movement (Jewish Enlightenment) was also evident. Supporters of the Haskalah held that Judaism must change, in keeping with the social changes around them. Other Jews insisted on strict adherence to halakha (Jewish law and custom).
