Bavaria, officially the Free State of Bavaria, is a landlocked state of Germany. It borders the states of Baden-Württemberg to the west, Hesse to the north-west, and Thuringia and Saxony to the north, as well as the countries of Switzerland and Austria to the south and the Czech Republic to the east. The state's capital and largest city is Munich; other major cities include Nuremberg, Augsburg, Regensburg, and Ingolstadt. With an area of 70,550 square kilometres (27,249 sq mi), it is the largest German state, and with 13.08 million inhabitants, the second-most populous.
The history of Bavaria begins with the settlement of Celtic tribes during the Iron Age. The territory was then ruled by the Roman Empire and incorporated into the provinces of Raetia and Noricum in the first century AD. Following the collapse of the Roman Empire, the Duchy of Bavaria was created in Francia in 555 AD. It later became part of East Francia and controlled territory in modern-day Austria, Slovenia and Italy. Within the Holy Roman Empire it gained elector status in 1623 during the Thirty Years' War, eventually becoming the Kingdom of Bavaria in 1806. Following the Unification of Germany, Bavaria remained a kingdom within the German Empire until the end of World War I. The modern state of Bavaria was established in 1945 and became part of West Germany in 1949.
The culture of Bavaria is heavily influenced by its Catholic heritage. The Bavarian language is a group of German dialects in both Bavaria and Austria with around 12 million speakers, making it the largest German dialect. Other major cultural influences of Bavaria include its cuisine, consisting of foods such as Weißwurst and Leberkäse, its architecture, largely focused on Alpine symbolism in southern Alpine regions, and its major festivals such as the Oktoberfest in Munich.
Modern Bavaria's borders consist of Altbayern as well as parts of the historical regions of Franconia and Swabia. There are 7 administrative regions of Bavaria, 3 of which are in Franconia and Altbayern and 1 of which is in Swabia. Bavaria has a tradition of conservatism; the CSU is the largest party in Bavaria and is known as the 'sister party' of the national CDU, being collectively known as the Union.
Though Bavaria has been occupied by humans since the Paleolithic era, Celtic tribes of the Bronze Age, such as the Boii were the first documented inhabitants of the Bavarian Alps. In June 2023, archeologists discovered a bronze sword, dated to the 14th century BC, in a former Celtic village; its workmanship so well-preserved "it almost shines." During the early modern era, these peoples were retrospectively romanticized as the most ancient culture of Bavaria, even though the Indo-European languages were relative newcomers to the region. Evidence of the ancient Straubing culture, Únětice culture and La Tène culture may be found in what is Bavaria today.
Archeologists know of a large Celtic Iron Age settlement which was founded in Feldmoching-Hasenbergl north of suburban Munich. Evidence suggests up to 500 people lived in the village from 450 BC. Local life appears to have centred around what could be a town hall or temple, and continued in different forms up to 1000 AD. In Manching, Upper Bavaria, an unfortified and semi-urban society appears to have prospered between the 3rd century BC until the early 1st century AD. The settlement featured food ovens, pottery kilns and metallurgical furnaces. By 200 BC the community there was active in trade—finds of coins, along with an icon-like golden tree suggest it was trading with distant Italo-Greek communities.
In the 1st century BC, Bavaria was conquered by the Roman Empire. An imperial military camp was built 60 km north-west of where Munich sits today, under orders of Augustus Caesar, between 8 and 5 BC. The camp later became the town of Augusta Vindelicorum, which would become the capital of the Roman province of Raetia. Another fort was founded in 60 AD, west of modern-day Manching, as evidenced by a legionnaire's sandal found near remains of an ancient fort.
In the 530s, the Merovingian dynasty incorporated the kingdom of Thuringia after their defeat by the Franks. The Baiuvarii were Frankicised a century later. The Lex Thuringorum documents an upper class nobility of adalingi. From about 554 to 788, the house of Agilolfing ruled the Duchy of Bavaria, ending with Tassilo III who was deposed by Charlemagne.
Tassilo I of Bavaria tried unsuccessfully to hold the eastern frontier against the expansion of Slavic peoples and the Pannonian Avars around 600. Garibald II seems to have achieved a balance of power between 610 and 616.
At Hugbert's death in 735, the duchy passed to Odilo of Bavaria from the neighboring Alemannia. Odilo issued a Lex Baiuvariorum for Bavaria, completed the process of church organization in partnership with Saint Boniface in 739, and tried to intervene in Frankish succession disputes by fighting for the claims of the Carolingian dynasty. He was defeated near Augsburg in 743 but continued to rule until his death in 748.
Saint Boniface completed the people's conversion to Christianity in the early 8th century. Tassilo III of Bavaria succeeded to rule Bavaria. He initially ruled under Frankish oversight but began to function independently from 763 onward. He was particularly noted for founding new monasteries and for expanding eastwards, oppressing Slavs in the eastern Alps and along the Danube and colonizing these lands. After 781, however, Charlemagne began to exert pressure and Tassilo III was deposed in 788. Dissenters attempted a coup against Charlemagne at Regensburg in 792, led by Pepin the Hunchback.
With the revolt of Henry II, Duke of Bavaria in 976, Bavaria lost large territories in the south and southeast.
One of the most important dukes of Bavaria was Henry the Lion of the house of Welf, founder of Munich, and de facto the second most powerful man in the empire as the ruler of two duchies. When in 1180, Henry the Lion was deposed as Duke of Saxony and Bavaria by his cousin, Frederick I, Holy Roman Emperor (a.k.a. "Barbarossa" for his red beard), Bavaria was awarded as fief to the Wittelsbach family, counts palatinate of Schyren ("Scheyern" in modern German). They ruled for 738 years, from 1180 to 1918. In 1180, however, Styria was also separated from Bavaria. The Electorate of the Palatinate by Rhine (Kurpfalz in German) was also acquired by the House of Wittelsbach in 1214, which they would subsequently hold for six centuries.
The first of several divisions of the duchy of Bavaria occurred in 1255. With the extinction of the Hohenstaufen in 1268, Swabian territories were acquired by the Wittelsbach dukes. Emperor Louis the Bavarian acquired Brandenburg, Tyrol, Holland and Hainaut for his House but released the Upper Palatinate for the Palatinate branch of the Wittelsbach in 1329. That time also Salzburg finally became independent from the Duchy of Bavaria.
In the 14th and 15th centuries, upper and lower Bavaria were repeatedly subdivided. Four Duchies existed after the division of 1392: Bavaria-Straubing, Bavaria-Landshut, Bavaria-Ingolstadt and Bavaria-Munich. In 1506 with the Landshut War of Succession, the other parts of Bavaria were reunited, and Munich became the sole capital. The country became a center of the Jesuit-inspired Counter-Reformation.
In 1623, early in the Thirty Years' War, the Bavarian duke replaced his relative the Elector Palatine among the Holy Roman Empire's powerful prince-elector, gaining both a vote in determining the Emperor thenceforth and special legal status under the Empire's laws. During the early and mid-18th century, the ambitions of the Bavarian prince-electors led to several wars with Austria as well as to occupations by Austria during the War of the Spanish Succession and the War of the Austrian Succession; on one occasion, the Bavarian House of Wittelsbach secured the election of one of its own members rather than a Habsburg as emperor.
To mark the unification of Bavaria and the Electoral Palatinate, both being principal Wittelsbach territories, Elector Maximilian IV Joseph was crowned king of Bavaria. King Maximilian Joseph was quick to change the coat of arms. The various heraldic symbols were replaced and a classical Wittelsbach pattern introduced. The white and blue lozenges symbolized the unity of the territories within the Bavarian kingdom.
