Romania. The Cyrillic inscription from 943 refers to a "župan Dimitrie". Byzantine troops occupied large portions of Bulgaria, including modern Dobruja, under Emperor John I Tzimiskes (969–976). After his death an anti-Byzantine uprising led by four brothers broke out. One of the brothers, David, was killed by Vlachs in the present-day border region between Greece and North Macedonia. In 1018, the Byzantines conquered the whole territory of the Bulgarian Empire and the Archbishop of Ohrid acquired ecclesiastic jurisdiction in 1020 over the Vlachs living there. Hungarians in the Carpathian Basin (c. 895–c. 1000) The way taken by the Hungarians across the Carpathian Mountains when they started the conquest of the Carpathian Basin varies from source to source. According to Gesta Hungarorum, the Hungarians descended through the northern passes to the lowlands, bypassing Transylvania, and only began the invasion of the regions east of the Tisa after the conquest of the western regions. Gesta Hungarorum says the Vlach Gelou of Transylvania died fighting the Hungarians, while his subjects chose "for themselves as lord Tétény", one of the Hungarian leaders. Anonymus also wrote of Menumorut's defeat, but said he preserved his rule in Crişana until his death by giving his daughter in marriage to Zolta, heir to Árpád, the head of the Hungarians. In a contrasting account, the Illuminated Chronicle writes of Hungarians fleeing through the eastern passes of the Carpathian Mountains to Transylvania where they "remained quietly" and "rested their herds" for a while before moving further west. The so-called "Cluj group" of small inhumation cemeteriesgraves with west–east orientation, often containing remains of horses appeared on both sides of the Apuseni Mountains around 900. Their military character evidences that the people using them formed a "double defensive line" organized against the Pechenegs. Transylvanian cemeteries of the "Cluj group" cluster around salt mines. Emperor Constantine VII Porphyrogenitus identified "the whole settlement" of Hungary with the lands where the rivers Criş, Mureş, Timiş, Tisa and Toutispossibly the Begaran around 950. The concentration of objects of Byzantine provenance at the confluence of the Mureş and Tisa shows that this territory was a regional center of power. Accordingly, the seat of Gyula, a Hungarian chieftain baptized in Constantinople around 952, most probably existed in this region. On the other hand, Hungarian chronicles associate Gyula's family with Transylvania.
