Ulrich Zasius (1461 – 24 November 1535 or 1536) was a German jurist.
Zasius was born atKonstanz (currentBaden-Württemberg) in 1461.
After studying atTübingen he first became episcopal notary at Constance, then town clerk atBaden inAargau in 1489, and atFreiburg in 1493. From 1496 to 1499 he directed theLatin school at Freiburg.
In 1499 he studiedlaw at theUniversity of Freiburg, was appointed lecturer ofrhetoric andpoetry there in 1500 and professor ofjurisprudence in 1506. In 1502 he was also clerk of court at Freiburg. On April 2 of that year, he joined in with an alliance ofburghers and scholars to attempt to expel the Jews of Waldkirch. In 1503, he was appointed legal adviser to the university. In 1505 he authored a treatise assaulting Jewish parental rights which was published in Strasbourg in 1508.[1] In 1508, he was appointed imperial counselor. Applying the tendencies of theHumanists to jurisprudence, he scouted the strained and barbarous comments of the glossators and endeavoured to restore the genuine text. It was probably due to the literary controversies which he had withEck, that he at first favoured the doctrines ofMartin Luther. After 1521 he was a zealous opponent of Luther and died a firm adherent of theRoman Catholic faith.
He died at Freiburg in 1535 or 1536. His juridical works were published posthumously (Lyon, 1548, 1550–1; 3 vols.,Frankfurt, 1590).
