Saka horsemen replaced Greek kings in northwest India
Iranic Scythian nomads drifted south from Central Asia into Afghanistan, eastern Iran, and the Indus world across the mid-second century BCE to the fourth century CE. Maues planted Saka power in Gandhara; their successors swallowed Indo-Greek realms before Kushan pressure remade the map again.
Indo-Scythians, or Indo-Sakas, were Iranic Scythian nomads who migrated from Central Asia into present-day Afghanistan, eastern Iran, and the northwestern Indian subcontinent. Movements stretched from the mid-second century BCE into the fourth century CE. Maues, in the first century BCE, was the first Saka king on the subcontinent, establishing power in Gandhara, the Indus Valley, and beyond. They conquered Indo-Greeks and other locals before apparent subjugation by the Kushan Empire.
The "Indo-Scythian invasion" marks a major turn in regional history, sparked as Central Asian groups fled conflict with tribes such as the Xiongnu and moved toward Bactria and India. Ancestors are generally tied to Saka (Scythian) Kamboja tribes. "Saka" itself is a broad label for a cultural continuum of early nomads from Siberia and the steppe into Xinjiang rather than one neat ethnicity. Western Indian Sakas spoke the Saka (Khotanese) language first documented in the Tarim Basin.
Persian-period armies were multiethnic: during the Achaemenid Indus conquest around 515 BCE, Saka likely marched alongside Bactrians, Parthians, and Sogdians, according to the empire's mixed muster lists recalled by Herodotus. Some scholars, including Michael Witzel and Christopher I. Beckwith, even propose that the Shakya clan of Gautama Buddha were originally Central Asian Scythians, linking the ethnonym Śākya to "Scythian" and offering one explanation for later strong Saka patronage of Buddhism—though that claim remains interpretive rather than settled fact.
