The Sakas or Scythians were nomadic central asian tribes who were turned out of their home land (165 B.C) by Yueh-chi(Kushanas).The in-roads made by these tribes were due to the prevailing conditions in Central Asia and North-western China.
The sakas were divided in to five branches and established themselves in various parts of India.
One branch settled in Afghanistan
Second branch settled in Punjab with capital as Taxila.
The third branch settled in Mathura.
The fourth branch settled in Saurastra and Maharastra.
