The kingdom of Tushara, according to ancient Indian literature, such as the epic Mahabharata, was a land located beyond north-west India. In the Mahabharata, its inhabitants, known as the Tusharas, are depicted as mlechchas ("barbarians") and fierce warriors.
Modern scholars generally see Tushara as synonymous with the historical "Tukhara", also known as Tokhara or Tokharistan – another name for Bactria. This area was the stronghold of the Kushan Empire, which dominated India between the 1st and 3rd centuries CE.
