Political map of India around 590. The Chalukyas are the dominant dynasty in the Deccan. The Late Guptas reach their zenith, soon to be brought to a halt (why is unclear - maybe by incursions of the Chalukya king Kirtivarman I, or by king Shashanka of Gauda). Meanwhile, the Vardhanas become a regional player as well.
