The Sakas were the foreign conquerors who set up their rule in the central and western India while the Kushanas entrenched themselves in the north and the Satavahanas in parts of the central India. The Saka rule lasted from 35 A. D through 405. The areas of Saurashtra and Malwa formed part of the Saka Empire.
The Saka Era was started by King Chasthana to mark his ascension to the throne. Almost around the same period from the 2nd century B.C. through the 3rd century A.D. there existed in the Himalayan Region a kingdom called Kundina, which had connections with the Mahajanapadas. There are mentions of this kingdom in the epics of India.
