The following table shows the various kingdoms, provinces and tribes mentioned in the epic Mahabharata. As kingdoms they represent a geographical region that existed in ancient India which was then known as the Bharatavarsha and as the Jamvudvipa (the continent of the Jamvu tree). As tribes they existed at some geographical region at some point of time and moved to other regions or spread into multiple regions at different points of time.
An important passage in the Mahabharata useful for anybody studying about the ancient kingdoms and tribes of Bharatavarsha is found at MBh 6.9 (Mahabharata, Bhishma Parva (volume 6), chapter 9).
