Again the Jewish communities of Holland appealed to Burmania, and again he pleaded, urged, and remonstrated with the Austrian Reichskanzler (Chancellor), that "sovereigns, more than other persons, are responsible to God and man for their deeds."
Thereupon, Burmania, supported by the ambassadors of England, Poland, and Turkey, directed his energies toward averting the expulsion of the Jews from the whole of Bohemia, which was to take place in June.
A royal edict was issued on 8 April 1745, ordering all Jews of Moravia also to emigrate within a short time.
Burmania endeavored to have repealed the edict which was issued on 25 June 1746, prohibiting all Jews from coming within two hours' distance of Prague; but he was not successful.
Finally, however, on July 1748, Maria Theresa revoked the edict of 18 December 1744 "on account of the pressure from the foreign ambassadors" and the Jews were allowed to return to Prague.
