The 610s decade ran from January 1, 610, to December 31, 619.

His first major act is to change the official language of the Eastern Roman Empire from Latin to Greek (already the language of the vast majority of the population). Because of this, after AD 610, the Empire is customarily referred to as the Byzantine Empire (the term Byzantine is a modern term invented by historians in the 18th century; the people of the Empire itself always referred to themselves as "Ρωμαῖος" — tr. Rōmaios, Roman).
