East Central Europe (604–615 CE): Increasing Avar Power, Strengthening of Bohemia and Moravia, and Expanding Slavic Influence
Between 604 and 615 CE, East Central Europe—encompassing Poland, Czechia, Slovakia, Hungary, and those portions of Germany and Austria lying east of 10°E and north of a line stretching from roughly 48.2°N at 10°E southeastward to the Austro-Slovenian border near 46.7°N, 15.4°E—continued to witness significant geopolitical shifts. The Avar Khaganate further solidified its dominant position, intensifying both military campaigns and diplomatic maneuvers, particularly towards the Byzantine frontier and the developing West Slavic entities. Meanwhile, early state structures in Bohemia and Moravia became increasingly organized and culturally distinct, firmly establishing these territories as pivotal regional entities. Bavarian diplomatic and trade interactions continued to provide critical connections between Frankish, Slavic, and Avar spheres, reinforcing the region's economic importance.
