Azes I - BASILEOS BASILEON of Indo-Scythian Kingdom from ~48/47 BC to 25 BC
Azes I was an Indo-Scythian ruler who completed the domination of the Scythians in Gandhara.

Although Maues and his successors had conquered the areas of Gandhara, as well as the area of Mathura from 85 BCE forming the Northern Satraps, they were unsuccessful against the Indo-Greek kings remaining behind the Jhelum River in eastern Punjab.

Azes's most lasting legacy was the foundation of the Azes era. It was widely believed that the era was begun by Azes's successors by simply continuing the counting of his regnal years.
