The Tziganes research made me curious: someone told me that actually Tziganes had populated India!! It is quite not accurate, though India is a real melting pot, and this since prehistoric times!
I made a small synthesis of all that… (and that was not easy!)
At the beginning there was nothing.
Then there was the Indus civilization – about which we apparently don’t know much.
And after that there was a big mess.
Here is how it goes (please tell me if I got it wrong!):
§ Indus civilization
§ Invasion of Indus valley by the Aryens of Bactria (around 1000 BC).
§ Invasion of Indus valley by the Persians (end of the 6th century BC)
§ Invasion of Indus valley by the Greeks who kept coming and leaving (from 325 to 50 BC) during the local Maurya dynasty (325 to 187 BC).
§ Invasion by the Indo-European tribes coming from China (the Yue Tché and the white Huns) (from 45 to 550).
§ Muslim dominations alternately between the Turks and the Afghans (from 997 to 1526).
§ Turko-Mughal dominations (from 1526 to 1857, year when the last Mughal emperor died).
§ European invasions (first Portuguese (1535) then Danish, French and British).
An approximative map (by myself):
