The one way that the Byzantine Empire shared its ideas throughout Eastern Europe was by sending missionaries to other regions to spread Christianity.

Explanation:

The conflicts that were happening between the Arab Muslims and the Byzantines gave rise to the idea of establishing religious dominance in the region. The Arab Muslims were mostly engaged in converting the non-muslim populations from the conquered regions for the sake of far and wide dissemination of Islam. Hence, the Byzantine Empire also chose to send missionaries to other regions to spread Christianity.
