"Huldrych Zwingli[a] or Ulrich Zwingli[b] (1 January 1484 – 11 October 1531) was a leader of the Reformation in Switzerland, born during a time of emerging Swiss patriotism and increasing criticism of the Swiss mercenary system. He attended the University of Vienna and the University of Basel, a scholarly center of Renaissance humanism. He continued his studies while he served as a pastor in Glarus and later in Einsiedeln, where he was influenced by the writings of Erasmus.
In 1519, Zwingli became the pastor of the Grossmünster in Zürich where he began to preach ideas on reform of the Catholic Church. In his first public controversy in 1522, he attacked the custom of fasting during Lent. In his publications, he noted corruption in the ecclesiastical hierarchy, promoted clerical marriage, and attacked the use of images in places of worship. In 1525, he introduced a new communion liturgy to replace the Mass. He also clashed with the Anabaptists, which resulted in their persecution. Historians have debated whether or not he turned Zürich into a theocracy." - (en.wikipedia.org 27.10.2019)
