Commentary from other sources:
1) “…when the Habsburg dynasty came to power under Austrian Archduke Ferdinand…The Jews of Bohemia, Moravia, and Silesia were eventually allowed to return to their homes following the expulsion, but even though Habsburg rule was among the most liberal in all of Europe, a law was enacted in 1551 requiring Jews to wear distinctive clothing to separate them from the majority, Christian population.”
