Ulrich Hugwald (Udalricus Hugualdus, Huldaricus Mutius Hugwaldus; 1496–1571) was a Swiss humanist scholar and Reformer.
Born in Wilen near Bischofszell, county of Thurgau, he was enrolled in the theological faculty in Basel University from 1519. He published critical pamphlets with Basel printer Adam Petri from 1520. He was in correspondence with a number of reformers, such as Vadianus, Michael Stifel, Jacques Lefèvre d'Étaples and Guillaume Farel. He also opened a private school of rhetorics in Basel. In 1524, he debated with Oecolampadius and Thomas Müntzer on the topic of believer's baptism. He joined the Basel Anabaptists in 1525, and was consequently imprisoned. He retired to his native Thurgau, working as a craftsman and farmer for some time. On his return to Basel, he distanced himself from the Anabaptists and was no longer active in religious debate. He taught at the Basel gymnasium from 1535, becoming rector in 1540, and he was professor for logic and ethics at the University of Basel from 1542.
In 1539, he published De Germanorum prima origine, a chronistic account of the Germanic peoples (edited by Struve in 1726). In an early expression of German nationalism, the publication aimed to defend the antiquity and nobility of the German race against the opinion held by Italian humanists which considered the Germans barbarous and enlightened only by Latin learning. Hugwald's work is substantially based on the Chronography by Swabian historian Johannes Nauclerus, published in 1516, to a lesser degree drawing on Franciscus Irenicus, Heinrich Bebel, Beatus Rhenanus, and others. The work is therefore of little value independent of that of Nauclerus except for its expressions of early German national sentiment paired with a patriotic love of his own homeland in Switzerland (Müller 1886).
Huldrych or Ulrich Zwingli 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.

Nikolaus Storch was a German weaver and radical lay-preacher in the Saxon town of Zwickau. He and his followers, known as the Zwickau Prophets, played a brief role during the early German Reformation years in south-east Saxony, and there is a view that he was a forerunner of the Anabaptists. In the years 1520–1521, he worked closely with the radical theologian Thomas Müntzer.

In 1521, after studying theology in Freiburg and Tübingen, Reublin became the pastor at St. Alban in Basel and began to advocate reform. St. Alban was soon the center of the evangelical movement in Basel. In the Fall of 1522 Reublin was expelled from the city for his Reformation sermons and moved to Witikon in 1524, where he became the local pastor and preached against infant baptism. Reublin was with Conrad Grebel and Felix Manz in Zürich in January 1525 at the birth of the Anabaptist movement. Reublin took part in a disputation on 17 January 1525 after which Grebel, Mantz and Reublin were given eight days to leave the canton.
