Maurya Empire and Gupta Empire are the most significant but there has been more than that.
Hope this helps!
Habsburg So the WWI Emperor of Austro-Hungary and Karl here are not from an unbroken male line and therefore not *actually von Habsburgs but they are descendants. Anymale line descendants who have the original name von Habsburg are most likely average people by now (but they are still around).
Are they any descendents from the Habsburg Empire today?
