“Order” of Friedrich II to the Jewry of Vienna [Present-day Austria] [Provisional]: “[..] the Jews are Our chamber-servants (‘servi camerae nostrae’) [… however] 3) in keeping with the command of imperial authority of ancient times, if the Christian princes so choose, [they] shall be able to exclude Jews from the tenured posts of civil servants. […]” [Researcher’s note: This law contained a number of privileges afforded to the Jewry of Vienna, except the section that grants the ruling princes – under whose domain Jews lived at that time – to excluded them from civil servant positions if they so choose.]
