The <entity_1> in <entity_4> or <entity_5> was an unsuccessful <entity_3> of the city of <entity_2>, the major Byzantine stronghold in the region, by the Avars and the Slavic tribes (Sclaveni) who had settled in the city's vicinity. The Avar attack materialized in <entity_4> (or possibly <entity_5>), as they needed time to mobilize their various subject tribes. For a generation, until the <entity_0>, <entity_2> would remain in peace with its Slavic neighbours.
