Czech lands in the context of "Czech Silesia"

Moravia is a historical region in the east of the Czech Republic and one of three historical Czech lands, with Bohemia and Czech Silesia.

The medieval and early modern Margraviate of Moravia was a crown land of the Lands of the Bohemian Crown from 1348 to 1918, an imperial state of the Holy Roman Empire from 1004 to 1806, a crown land of the Austrian Empire from 1804 to 1867, and a part of Austria-Hungary from 1867 to 1918. Moravia was one of the five lands of Czechoslovakia founded in 1918. In 1928 it was merged with Czech Silesia, and then dissolved in 1948 during the abolition of the land system following the communist coup d'état.

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.

German Bohemians (German: Deutschböhmen und Deutschmährer [ˈdɔʏtʃˌbøːmən] ; Czech: čeští Němci a moravští Němci, lit. 'German Bohemians and German Moravians'), later known as Sudeten Germans (German: Sudetendeutsche [zuˈdeːtn̩ˌdɔʏtʃə] ; Czech: sudetští Němci), were ethnic Germans living in the Czech lands of the Bohemian Crown, which later became an integral part of Czechoslovakia. Before 1945, over three million German Bohemians constituted about 23% of the population of the whole country and about 29.5% of the population of Bohemia and Moravia. Ethnic Germans migrated into the Kingdom of Bohemia, an electoral territory of the Holy Roman Empire, from the 11th century, mostly in the border regions of what was later called the "Sudetenland", which was named after the Sudeten Mountains.

The process of German expansion was known as Ostsiedlung ("Settling of the East"). The name "Sudeten Germans" was adopted during rising nationalism after the fall of Austria-Hungary in the aftermath of First World War. After the Munich Agreement (1938), the so-called Sudetenland became part of Germany.

The Duchy of Bohemia was established in 870 and raised to the Kingdom of Bohemia in 1198. Several Bohemian monarchs ruled as non-hereditary kings and first gained the title in 1085. From 1004 to 1806, Bohemia was part of the Holy Roman Empire, and its ruler was an elector. From 1526 to 1804, the Kingdom of Bohemia, together with the other lands of the Bohemian Crown, was ruled under a personal union as part of the Habsburg monarchy. From 1804 to 1918, Bohemia was part of the Austrian Empire, which itself was part of the dual monarchy of Austria-Hungary from 1867 to 1918. Following the dissolution of the monarchy, the Bohemian lands, now also referred to as Czech lands, became part of Czechoslovakia, and they have formed today's Czech Republic since the 1993 dissolution of Czechoslovakia.

The Hussites (Czech: Husité or Kališníci, "Chalice People"; Latin: Hussitae) were a Czech proto-Protestant Christian movement influenced by both the Byzantine Rite and John Wycliffe that followed the teachings of reformer Jan Hus (fl. 1401–1415), a part of the Bohemian Reformation.

The Czech lands had originally been Christianized by Byzantine Greek missionaries Saints Cyril and Methodius, who introduced the Byzantine Rite in the Old Church Slavonic liturgical language and the Byzantine tradition of Communion in both kinds administered by the holy spoon. Over the centuries that followed, however, the Roman Rite in Ecclesiastical Latin, which is less easily understood than Slavonic by native speakers of Old Czech, was imposed upon the Czech people despite considerable public resistance, by German-speaking bishops, beginning with Wiching, from the Holy Roman Empire. (See also Sázava Monastery). As a cultural memory of both communion in both kinds and the Divine Liturgy in a language closer to the vernacular is believed to have survived well into the Renaissance, the ideas of Jan Hus and others like him swiftly gained a wide public following. After the trial and execution of Hus at the Council of Constance, a series of crusades, civil wars, victories and compromises between various factions with different theological agendas broke out. At the end of the Hussite Wars (1420–1434), the now Catholic-supported Utraquist side came out victorious from protracted conflict against Jan Žižka and the Taborites, who embraced the more radical theological teachings of John Wycliffe and the Lollards, and became the dominant Hussite group in Bohemia.
