in their favor, organized a splendid celebration on November 15, 1790, the day of his coronation; on January 10, 1791, the king approved the bill of the Diet; and the following law, drafted in conformity with the royal decision, was read by Judge Stephen Atzel in the session of February 5: "In order that the condition of the Jews may be regulated pending such time as may elapse until their affairs and the privileges of various royal free towns relating to them shall have been determined by a commission to report to the next ensuing Diet, when his Majesty and the estates will decide on the condition of the Jews, the estates have determined, with the approval of his Majesty, that the Jews within the boundaries of Hungary and the countries belonging to it shall, in all the royal free cities and in other localities (except the royal mining-towns), remain under the same conditions in which they were on Jan. 1, 1790; and in case they have been expelled anywhere, they shall be recalled."

The De Judaeis law was gratefully received by the Jews; for it not only afforded them protection, but also gave them the assurance that their affairs would soon be regulated. Still, although the Diet appointed on February 7, 1791, a commission to study the question, the amelioration of the condition of the Hungarian Jews was not effected till half a century later, under Ferdinand V (r. 1835–1848), during the session of the Diet of 1839–1840. It is estimated that the Jewish population in Hungary grew by about 80% between 1815 and 1840, bolstered by immigration due to the perception of royal tolerance.

From now on much attention was paid to the teaching of Hungarian in the schools; Moritz Bloch (Ballagi) translated the Pentateuch into Hungarian, and Moritz Rosenthal the Psalms and the Pirkei Avoth. Various communities founded Hungarian reading-circles;
