Northern Satraps in the context of "Western Kshatrapa"

The Indo-Scythian Kingdom, also known as Indo-Sakas, were a group of nomadic people of Iranic Scythian origin who migrated from Central Asia southward into the Indus Valley region of present-day Pakistan and also regions of Afghanistan, Eastern Iran and northern India. The migrations persisted from the middle of the second century BCE to the fourth century CE.

The first Saka king in the subcontinent was Maues/Moga (first century BCE) who established Saka power in Gandhara, the Indus Valley, and other regions. The Indo-Scythians extended their supremacy over the north-western subcontinent, conquering the Indo-Greeks and other local peoples. They were apparently subjugated by the Kushan Empire's Kujula Kadphises or Kanishka. The Saka continued to govern as satrapies, forming the Northern Satraps and Western Satraps. The power of the Saka rulers began to decline during the 2nd century CE after the Indo-Scythians were defeated by the Satavahana emperor Gautamiputra Satakarni. Indo-Scythian rule in the northwestern subcontinent ended when the last Western Satrap, Rudrasimha III, was defeated by the Gupta emperor Chandragupta II in 395 CE.

Strato III Philopator (Greek: Στράτων Γ΄ Φιλοπάτωρ; epithet means "the Father-loving") was an Indo-Greek king who ruled c. 25 BCE to 10 CE. He is only known through the joint coins with his father Strato II. He may have been supplanted, in conjunction with his father or later as an independent king, by the Indo-Scythian Northern Satraps, particularly Rajuvula and Bhadayasa, whose coins were often copied. Strato was the last of the line of Diodotus and independent Hellenistic king to rule at his death in 10 AD.

The Indo-Scythians or Indo-Sakas were the branch of Saka empire in South Asia. Indo-Scythians were a group of nomadic Iranian peoples of Scythian origin who migrated from Central Asia southward into the northwestern Indian subcontinent. They started expansion in South Asia from 200 to 100 BCE and established rule between 100 and 80 BCE, their rule in Indian subcontinent was lasted until 415s CE.

The first Saka king of India was Maues/Moga (1st century BCE) who established Saka power in Gandhara. The Indo-Scythians extended their supremacy over north-western subcontinent, conquering the Indo-Greeks and other local kingdoms. The Indo-Scythians were apparently subjugated by the Kushan Empire, by either Kujula Kadphises or Kanishka. Yet the Saka continued to govern as satrapies, forming the Northern Satraps and Western Satraps. The power of the Saka rulers started to decline in the 2nd century CE after the Indo-Scythians were defeated by the Satavahana emperor Gautamiputra Satakarni. Indo-Scythian rule in the northwestern subcontinent ceased when the last Western Satrap Rudrasimha IIII was defeated by the Gupta emperor Chandragupta II in 395 CE. Later Western Saka rulers (c. 396 to 415 CE) were conquered by Imperial Gupta Empire and it brings to end of Saka rule in Indian subcontinent.
