Great Moravia: The First Major Slavic State in Central Europe

Great Moravia was the first large Slavic state in Central Europe, flourishing from about 833 until the early 10th century around the Morava River in today’s Czech Republic and Slovakia. Under its princes Mojmir I, Rastislav and Svatopluk I it rivalled the Frankish kingdoms on its borders. It is best remembered as the land that invited the Byzantine missionaries Cyril and Methodius, whose work shaped the written culture of the Slavic world.

Origins and rise

Slavs had settled in the Morava valley by the 6th century. After Charlemagne’s Franks destroyed the Avar state in the 790s, local Slavic rulers gained room to expand. The Moravians first appear in Frankish records in 822, when their envoys attended an assembly of Emperor Louis the Pious.

Around 833 Prince Mojmir I united the Moravian lands and drove out Pribina, a rival prince based at Nitra in today’s Slovakia. This union of the Morava and Nitra regions is usually regarded as the beginning of Great Moravia. The name itself was coined later by the Byzantine emperor Constantine VII, writing around 950.

Rastislav and the Byzantine mission

In 846 the East Frankish king Louis the German replaced Mojmir with his nephew Rastislav, hoping for a loyal client. Rastislav instead built fortresses and resisted Frankish control for over twenty years.

To reduce the influence of Frankish clergy, Rastislav asked the pope for teachers, and then in 862 turned to the Byzantine emperor Michael III. The emperor sent the brothers Constantine (later Cyril) and Methodius, who arrived in 863 with a new alphabet and Slavonic church books. Their work is described in Cyril and Methodius.

In 870 Rastislav was betrayed by his nephew Svatopluk, handed over to the Franks, blinded and imprisoned.

Svatopluk I and the height of power

Svatopluk I (r. 871-894) first served the Franks, but soon led a Moravian revolt and won independence, confirmed by the Peace of Forchheim in 874. Over the next two decades he extended his rule or overlordship over Bohemia, the lands of the Vistulans in southern Poland, and parts of Pannonia in modern Hungary.

Svatopluk supported Methodius, whom the pope had made archbishop, though he also favoured Latin clergy. In 880 Pope John VIII issued the letter Industriae tuae, which placed Svatopluk under papal protection and allowed the Slavonic liturgy. After Methodius died in 885, his opponent Bishop Wiching prevailed, and Methodius’s disciples were expelled. Several found refuge in Bulgaria.

Archaeology

Written sources for Great Moravia are scarce and mostly Frankish, so archaeology is essential. The fortified centre at Mikulčice in southern Moravia contained a palace and at least a dozen churches, some of stone, within its walls. Other major sites include Staré Město near Uherské Hradiště, Pohansko near Břeclav, Nitra and Devín.

Rich graves have yielded gilded spurs, earrings and other jewellery that combine Byzantine, Carolingian and local styles. Most historians place the state’s core in Moravia and western Slovakia, although a minority have argued for a location further south, along the Great Morava in Serbia or near Sirmium.

Society and religion

Great Moravia was a society of fortified centres, each surrounded by farming villages and craft workshops. Its people grew cereals, kept livestock and produced iron tools, weapons and fine metalwork. Power rested with the prince and a warrior elite, whose members were buried with swords, spurs and imported luxury goods.

Christianity reached the Moravians before the Byzantine mission, mainly through Frankish clergy from Bavaria and missionaries from northern Italy and the Adriatic. A church at Nitra is said to have been consecrated by the archbishop of Salzburg around 828, before Nitra joined Moravia. The many churches found at Mikulčice and elsewhere show that the elite had largely accepted the new faith by the mid-9th century.

Moravia’s position between the Frankish East and the Byzantine world made religion a political question. Choosing Latin or Slavonic clergy also meant choosing whose influence to accept, which explains the bitter disputes around Methodius.

Fall to the Magyars

After Svatopluk’s death in 894 his sons Mojmir II and Svatopluk II fought each other, and Bohemia and other territories broke away. At the same time the Magyars (Hungarians) moved into the Carpathian Basin from the east and began raiding neighbouring lands, as told in Hungarian conquest of the Carpathian Basin.

Mojmir II disappears from the written record in the early 900s and probably died around 906. In 907 the Magyars destroyed a Bavarian army near Pressburg (Bratislava), and by then Great Moravia no longer existed as a state. Some of its fortified centres were abandoned, while others continued on a smaller scale.

Why it matters

Great Moravia was short-lived, but its influence lasted far longer. The mission it invited created the first Slavic literary language and alphabet, which spread to Bulgaria, Rus and beyond. Czechs and Slovaks regard it as the earliest shared chapter in their history, and its excavated sites are among the most important early medieval monuments in Central Europe.
