Utraquism in the context of "Hussites"

The Bohemian Revolt (German: Böhmischer Aufstand; Czech: České stavovské povstání; 1618–1620) was an uprising of the Bohemian estates against the rule of the Habsburg dynasty that began the Thirty Years' War. It was caused by both religious and power disputes. The estates were almost entirely Protestant, mostly Utraquist Hussite but there was also a substantial German population that endorsed Lutheranism. The dispute culminated after several battles in the final Battle of White Mountain, where the estates suffered a decisive defeat. This started re-Catholisation of the Czech lands, but also expanded the scope of the Thirty Years' War by drawing Denmark and Sweden into it. The conflict spread to the rest of Europe and devastated vast areas of Central Europe, including the Czech lands, which were particularly stricken by its violent atrocities.

The Bohemian Reformation (also known as the Czech Reformation or Hussite Reformation), preceding the Reformation of the 16th century, was a Christian movement in the late medieval and early modern Kingdom and Crown of Bohemia (mostly what is now present-day Czech Republic, Silesia, and Lusatia) striving for a reform of the Catholic Church. Lasting for more than 200 years, it had a significant impact on the historical development of Central Europe and is considered one of the most important religious, social, intellectual and political movements of the early modern period. The Bohemian Reformation produced the first national church separate from Roman authority in the history of Western Christianity, the first apocalyptic religious movement of the early modern period, and the first pacifist Protestant church.

The Bohemian Reformation included several theological strains that developed over time. Although it split into many groups, some characteristics were shared by all of them – communion under both kinds, distaste for the wealth and power of the church, emphasis on the Bible preached in a vernacular language and on an immediate relationship between man and God. The Bohemian Reformation included particularly the efforts to reform the church before Hus, the Hussite movement (including e.g. Taborites and Orebites), the Unity of the Brethren and Utraquists or Calixtines.

Albrecht Wenzel Eusebius von Wallenstein, Duke of Friedland (pronunciation; 24 September 1583 – 25 February 1634), also von Waldstein (Czech: Albrecht Václav Eusebius z Valdštejna), was a Bohemian military leader, statesman and a major figure of the Thirty Years' War, fighting on the Catholic side as supreme commander of the armies of Holy Roman Emperor Ferdinand II. His successful martial career made him one of the richest and most influential men in the Holy Roman Empire by the time of his death. He is considered one of the most important military leaders produced by the early modern period.

Wallenstein was born in the Kingdom of Bohemia into a poor Czech Protestant noble family, affiliated with the Utraquist Hussites. He acquired a multilingual university education across Europe and converted to Catholicism in 1606. A marriage in 1609 to the wealthy widow of a Bohemian landowner gave him access to considerable estates and wealth after her death at an early age in 1614. Three years later, Wallenstein embarked on a career as a mercenary by raising forces for the Holy Roman Emperor in the Uskok War against the Republic of Venice.
