Due to the ongoing conflicts with the Arabs during the 670s, Constantine had been forced to conclude treaties in the west with the Lombards, who had captured Brindisi and Taranto.[20] Also in 680, the Bulgars under Khan Asparukh crossed the Danube into nominally Imperial territory and began to subjugate the local communities and Slavic tribes.[8] In 680, Constantine IV led a combined land and sea operation against the invaders and besieged their fortified camp in Dobruja.[21] Suffering from bad health, the Emperor had to leave the army, which panicked and was defeated by the Bulgars.[22] In 681, Constantine was forced to acknowledge the Bulgar state in Moesia and to pay tribute/protection money to avoid further inroads into Byzantine Thrace.[17] Consequently, Constantine created the Theme of Thrace.[20]	./cache/en-wikipedia-org-6333.html	./txt/en-wikipedia-org-6333.txt
