In 803, Krum of Bulgaria became Khan. The new, energetic ruler focused on the north-west where Bulgaria's old enemies the Avars experienced difficulties and setbacks against the Franks under Charlemagne.[citation needed] Between 804 and 806, the Bulgarian armies annihilated the Avars and destroyed their state. Krum took the eastern parts of the former Avar Khaganate and took over rule of the local Slavic tribes. Bulgaria's territory extended twice from the middle Danube to the north of present-day Budapest to the Dnester, though its possession of Transylvania is debatable.[citation needed] In 813 Khan Krum seized Odrin and plundered the whole of Eastern Thrace. He took 50,000 captives who were settled in Bulgaria across the Danube.[citation needed]
