With the commencement of the Hungarian Reform Era in 1825, especially after virtually all limitations on Jewish settlement were removed in 1840, the Kingdom's Jews underwent rapid urbanization and acculturation, and many began to assimilate. A gradual linguistic shift from Yiddish to German took place, and later to Hungarian. The pressures that motivated German Jews to seek aesthetic changes in their synagogues a generation earlier began to manifest themselves. In addition, the local Liberals – Lajos Kossuth among them – insisted that Emancipation would be granted only after Jews abandoned the customs that set them apart from society so that they could fully integrate. As in Germany, both moderate and extreme religious reformers in Hungary opposed this demand, claiming civil rights should be unconditional and that the changes they instituted were made for their own sake. However, there was a clear correlation between the levels of education and acculturation and support for change. At that time, the assimilated Jews had long since ceased to uphold traditional religious rules such as Sabbath observance and the requirement for Jewish-cooked food.
