Slavonia in the context of "Osijek"

Wenceslaus II Přemyslid (Czech: Václav II.; Polish: Wacław II Czeski; 27 September 1271 – 21 June 1305) was King of Bohemia (1278–1305), Duke of Cracow (1291–1305), and King of Poland (1296–1305).

He was the only son of King Ottokar II of Bohemia and Ottokar's second wife Kunigunda. He was born in 1271, ten years after the marriage of his parents. Kunigunda was the daughter of Rostislav Mikhailovich, lord of Slavonia, son of a Grand Prince of Kiev, and Anna of Hungary, daughter of Béla IV of Hungary. His great-grandfather was the German king Philip of Swabia. Wenceslaus II was the grandfather of the Holy Roman Emperor, Charles IV. He was a member of the Přemyslid dynasty.

Đakovo (pronounced [ˈdʑakɔʋɔ]; Hungarian: Diakovár, German: Diakowar, Serbian Cyrillic: Ђаково) is a town in the region of Slavonia, Croatia. Đakovo is the centre of the fertile and rich Đakovo region (Croatian: Đakovština [d͡ʑakǒːʋʃtina]).

The Vučedol culture (Croatian: Vučedolska kultura) flourished between 3000 and 2200 BC (the Chalcolithic period of earliest copper-smithing and arsenical bronze-smithing), centered in Syrmia and eastern Slavonia on the right bank of the Danube river, but possibly spreading throughout the Pannonian plain and western Balkans and southward. It was thus contemporary with the Sumer period in Mesopotamia, the Early Dynastic period in Egypt and the earliest settlements of Troy (Troy I and II). Archaeogenetics link the culture from Yamnaya migrations directly from the steppes that mixed with Neolithic people. The need for copper resulted in the expansion of the Vucedol Culture from its homeland of Slavonia into the broader region of central and southeastern Europe. The Vučedol culture is also known as the 'Zok culture' in Hungary, with regional variants including the 'Mako culture' and 'Nyirseg culture', and as the 'Laibach-Ljubljana culture' In the eastern Alpine area.

The Battle of Gorjani (Croatian: Bitka kod Gorjana, German: Schlacht bei Gorjani) or Battle of Đakovo (Hungarian: Diakovári csata) was fought on 9 October 1537 at Gorjani, a place in present-day Slavonia (today in eastern Croatia), between the towns of Đakovo and Valpovo, as part of the Little War in Hungary as well as the Hundred Years' Croatian–Ottoman War.

The Glagolitic script (/ˌɡlæɡəˈlɪtɪk/ GLAG-ə-LIT-ik, ⰳⰾⰰⰳⱁⰾⰻⱌⰰ, glagolitsa) is the oldest known Slavic alphabet. It is generally agreed that it was created in the 9th century for the purpose of translating liturgical texts into Old Church Slavonic by Saint Cyril, a monk from Thessalonica. He and his brother Saint Methodius were sent by the Byzantine Emperor Michael III in 863 to Great Moravia after an invitation from Rastislav of Moravia to spread Christianity there. After the deaths of Cyril and Methodius, their disciples were expelled from Moravia, and they moved to the First Bulgarian Empire instead. The Early Cyrillic alphabet, which was developed gradually in the Preslav Literary School by scribes who incorporated some Glagolitic letters when writing in the Greek alphabet, gradually replaced Glagolitic in that region. Glagolitic remained in use alongside the Latin script in the Kingdom of Croatia and alongside Cyrillic until the 14th century in the Second Bulgarian Empire and the Serbian Empire; in later periods, it was used mainly for cryptographic purposes.

Glagolitic also spread to the Kievan Rus' and the Kingdom of Bohemia. Although its use declined there in the 12th century, some manuscripts in the territory of the former retained Glagolitic inclusions for centuries. It had also spread to Duklja and Zachlumia in the Western Balkans, from where it reached the March of Verona. There, the Investiture Controversy afforded it refuge from the opposition of Latinizing prelates and allowed it to entrench itself in Istria, from which place it spread to nearby lands. It survived there and as far south as Dalmatia without interruption into the 20th century for Church Slavonic in addition to its use as a secular script in parts of its range, which at times extended into Bosnia, Slavonia, and Carniola, in addition to 14th–15th century exclaves in Prague and Kraków, and a 16th-century exclave in Putna.

Andrew III the Venetian (Hungarian: III. Velencei András, Croatian: Andrija III. Mlečanin, Slovak: Ondrej III., Italian: Andrea III il veneziano; c. 1265 – 14 January 1301) was King of Hungary and Croatia between 1290 and 1301. His father, Stephen the Posthumous, was the posthumous son of Andrew II of Hungary although Stephen's older half brothers considered him a bastard. Andrew grew up in Venice, and first arrived in Hungary upon the invitation of a rebellious baron, Ivan Kőszegi, in 1278. Kőszegi tried to play Andrew off against Ladislaus IV of Hungary, but the conspiracy collapsed and Andrew returned to Venice.

Being the last male member of the House of Árpád, Andrew was elected king after the death of King Ladislaus IV in 1290. He was the first Hungarian monarch to issue a coronation diploma confirming the privileges of the noblemen and the clergy. At least three pretenders—Albert of Austria, Mary of Hungary, and an adventurer—challenged his claim to the throne. Andrew expelled the adventurer from Hungary and forced Albert of Austria to conclude a peace within a year, but Mary of Hungary and her descendants did not renounce their claim. The Hungarian bishops and Andrew's maternal family from Venice were his principal supporters, but the leading Croatian and Slavonian lords were opposed to his rule.
