Bohemia

• 1. Introduction

  ›

  Bohemia sits at the westernmost edge of what is now the Czech Republic, covering an area of 52,065 square kilometers and home today to about 6.9 million people. Mountains ring it on almost every side: the Bohemian Forest to the southwest, the Ore Mountains to the northwest, the Giant Mountains to the northeast. Those natural walls did not keep the world out. They became the borders of a kingdom that spent two thousand years caught between empires, invaded, occupied, divided, and reunited. How did a Celtic tribe's abandoned homeland become one of Central Europe's most contested pieces of territory? And what is it, exactly, that Bohemia is today?

• 2. A Celtic Name, A Germanic Land

  ›

  In 194 BC, Roman forces met a Celtic people called the Boii at the Battle of Placentia, and again the following year at Mutina. The Boii lost both times. Survivors retreated north across the Alps, back toward a territory that Roman writers would later call Boiohaemum. The earliest mention of that name appears in Tacitus' Germania 28, written at the end of the first century AD. Strabo and Velleius Paterculus used it too. Linguists read the word as a compound: the tribal name Boio- joined with the Proto-Germanic word haimaz, meaning home. So Bohemia, in its oldest recorded form, meant the home of the Boii.

  By the time Roman writers were using that name, the Boii had largely moved on. Into the lightly inhabited territory came Suebic peoples speaking Germanic languages, and their king Marobodus used Bohemia's mountain-ringed terrain as a natural fortress. He built alliances with surrounding tribes, including at various times the Lugii, Quadi, Hermunduri, Semnones, and Buri. In the second century, his successors fought the emperor Marcus Aurelius. The region was not a backwater but a recurring flashpoint on Rome's northern frontier.

  The Czech name for the region, Cechy, has a different origin entirely. It comes from the Slavic ethnic group, the Czechs, who arrived from the east during the sixth or seventh century AD. Their language gradually replaced the older Germanic, Celtic, and Sarmatian tongues that had accumulated over centuries of migration.

• 3. Kingdom, Church, and Crown

  ›

  Bohemia entered the medieval era as part of the Slavic state of Great Moravia, under the rule of Svatopluk I, who reigned from 870 to 894. When Svatopluk died, the Moravian state weakened under Magyar incursions and eventually collapsed. Out of that collapse rose the Premyslid dynasty, a native monarchy that would rule the Czech lands for several hundred years. Their conversion to Christianity in the ninth century opened the door to close relations with the East Frankish Kingdom, which itself would evolve into the Holy Roman Empire.

  After a decisive battle at Lechfeld in 955, where the Holy Roman Empire and Bohemia together turned back invading Magyars, the German emperor Otto the Great granted Moravia to Boleslaus I of Bohemia. The first Premyslid rulers to use the title King of Bohemia were Vratislav II in 1085 and Vladislaus II in 1158, though their successors reverted to the lesser title of duke. The crown became hereditary under Ottokar I in 1198. His grandson Ottokar II, who ruled from 1253 to 1278, pushed the kingdom to its greatest early extent, briefly controlling what is now Austria and Slovenia.

  In the mid-thirteenth century, substantial German immigration began, partly to replace population lost during the Mongol invasion of Europe in 1241. Germans settled along the northern, western, and southern borders, as well as in towns throughout the kingdom. In the mining town of Sankt Joachimsthal, now known as Jachymov, large silver coins called Joachimsthalers were struck. Those coins gave their name to the thaler and, ultimately, to the dollar.

• 4. Charles IV and the Prague Zenith

  ›

  Charles IV became King of Bohemia in 1346, and two years later he founded Charles University in Prague, the first university in Central Europe. His reign brought the kingdom to its greatest political extent. He became the first king of Bohemia to be elected Holy Roman Emperor, and under his rule the Bohemian crown controlled Moravia, Silesia, Upper and Lower Lusatia, Brandenburg, an area near Nuremberg called New Bohemia, Luxembourg, and scattered towns across Germany.

  Prague in that era was not simply a regional capital but the seat of empire. The German spoken in Prague intermediated between Upper German and East Central German dialects and shaped the foundations of modern standard German. At the same time, the rector of Charles University, Jan Hus, was developing religious and philosophical ideas that would push the Czech language in the opposite direction, helping it become a vehicle for popular religious thought and setting the stage for a confrontation that would shake the entire continent.

• 5. Jan Hus and the Wars He Sparked

  ›

  During the Council of Constance in 1415, Jan Hus was condemned as a heretic despite having been granted formal safe conduct by Emperor Sigismund of Luxembourg before he made the journey. Hus had been invited to defend his positions before the council. On the 6th of July 1415, with the emperor's approval, he was burned at the stake.

  The execution ignited the Hussite Wars. A former mercenary named Jan Zizka of Trocnov led the Czech uprising, deploying howitzers, pistols, and fortified wagons in tactics that were unprecedented for the period. Zizka never lost a battle as commander. After his death, Prokop the Great led the Hussite armies, and they remained undefeated for another decade.

  The movement eventually split between the moderate Utraquists and the more radical Taborites. Battle-weariness allowed the Utraquists to defeat the Taborites at Lipany in 1434. Emperor Sigismund observed afterward that only the Bohemians could defeat the Bohemians. The Utraquists were nonetheless strong enough to negotiate a formal freedom of religion two years later, codified in the Compacts of Basel in 1436. Pope Pius II declared those compacts invalid in 1462.

  The upheaval produced a remarkable footnote: in 1458, George of Podébrady was elected to the Bohemian throne and proposed a pan-European Christian League that would unite all European states in a community based on shared religion. He dispatched Zdenek Lev of Rozmital to tour European courts and conduct negotiations. The project ultimately failed as George's standing with the papacy deteriorated, but the proposal was among the earliest visions of a unified European political order.

• 6. Habsburg Rule and the Thirty Years' War

  ›

  King Louis II of Hungary and Bohemia died at the Battle of Mohacs in 1526, and the Archduke Ferdinand I of Austria claimed the Bohemian throne. Bohemia became a constituent state of the Habsburg monarchy. Between 1599 and 1711, the Ottoman Empire and its vassals, particularly Tatar forces and Transylvania, repeatedly raided Moravia; hundreds of thousands were enslaved and tens of thousands killed.

  Bohemia had enjoyed relative religious freedom since 1436, and in 1609 the Holy Roman Emperor Rudolf II, himself a Catholic, issued the Maiestas Rudolphina at the urging of the Bohemian nobility, confirming the older Confessio Bohemica of 1575. That tolerance did not survive his successors. When Ferdinand II began suppressing Protestant rights, the resulting revolt triggered the Thirty Years' War in 1618.

  The Bohemian nobility elected Elector Frederick V, a Calvinist, as king in place of Ferdinand. Frederick's wife, Elizabeth Stuart, daughter of King James I of England and VI of Scotland, became known as the Winter Queen or Queen of Hearts. Their reign lasted less than a year before Frederick's defeat at the Battle of White Mountain in 1620. On the 21st of June 1621, twenty-seven Bohemian estate leaders and Jan Jesenius, rector of Charles University, were executed on Prague's Old Town Square. The rest were exiled and their lands given to Catholic loyalists, mostly of Bavarian and Saxon origin.

  The 1627 "renewed constitution" established German as a second official language in the Czech lands. German grew increasingly dominant among the ruling classes over the following century, though Czech persisted in the countryside. In 1749, the Bohemian Diet approved an administrative reform that merged the Royal Bohemian Chancellery with the Austrian Chancellery, further eroding the kingdom's formal independence.

• 7. Sudetenland, Occupation, Expulsion

  ›

  After the Munich Agreement of 1938, the border regions of Bohemia with predominantly German-speaking populations, the Sudetenland, were annexed by Nazi Germany. The following year, Germany absorbed the remainder of Bohemia and Moravia as the Protectorate of Bohemia and Moravia. The Slovak lands became a separate puppet state.

  During the occupation, the Germans operated the Theresienstadt Ghetto for Jews, prisoner-of-war camps including Dulag Luft Ost, Stalag IV-C, and Stalag 359, and the Ilag IV camp for interned Allied civilians. Seventeen subcamps of the Flossenburg concentration camp and sixteen subcamps of Gross-Rosen were located in the region, holding men and women of Polish, Soviet, Jewish, French, Yugoslav, Czech, Romani, and other backgrounds under forced labor.

  In 1942, Czechoslovak resistance fighters assassinated Reinhard Heydrich. In reprisal, German forces killed the entire population of the village of Lidice. In the spring of 1945, death marches from concentration camp subcamps moved through the region, and in May of that year, American, Polish, Czechoslovak, Soviet, and Romanian forces together captured the territory.

  After the war, the Potsdam Agreement provided the framework for the expulsion of the vast majority of Bohemia's German-speaking population. Czech authorities confiscated their property, which contemporary estimates placed at roughly a third of the entire Czechoslovak national income. Germans with specialized skills were briefly retained to transfer their knowledge. The Bohemian Romani local dialect was wiped out entirely, a consequence of the Nazi mass murder of Roma in the region.

• 8. Velvet Revolution and After

  ›

  In February 1948, the communist leader Klement Gottwald staged a coup after non-communist cabinet members resigned in protest over arbitrary measures in state institutions. Bohemia ceased to be a formal administrative unit of Czechoslovakia in 1949, when the country was reorganized into regions that ignored historical borders.

  In 1989, Agnes of Bohemia became the first saint from a Central European country to be canonized, the act performed by Pope John Paul II. Later that same year the Velvet Revolution ended communist rule. The Czech Republic became a separate state in 1993 following the Velvet Divorce. A 1997 constitutional act rejected the restoration of historical Czech lands as administrative units and confirmed the regional system in use since 2000. Petr Pithart, former Czech prime minister and president of the Senate, was among the most persistent advocates for restoring the land system; he argued the primary reason for its rejection was fear of Moravian separatism.

  Bohemia today has no single administrative form. Its territory is divided among Prague and several named regions, with its borders preserved mainly in dialect, in the names of railway stations and municipalities, and in the preamble of the Czech Republic's constitution, which begins: "We, citizens of the Czech Republic in Bohemia, Moravia and Silesia." In April 2025, a hoard weighing approximately 7 kilograms was unearthed beneath Zvicina Hill in north-eastern Bohemia, including nearly 4 kilograms of gold coins with an estimated value exceeding 7.5 million Czech crowns. The coins are believed to date to the eighteenth and nineteenth centuries, still being examined to determine their origins, a reminder that the ground beneath Bohemia has not finished giving up its past.
