How do I start the Saka reforms?

[Babro Swaggin]

It's been almost 200 hundred turns but I see no signs of the reformations,can someone tell me what are the requirements for these reformations?

In case anyone wanted to know,here are a things which I think might have something to do with this problem:-

1-Baktra,a city previously owned by the faction,well,Baktra until I conquered it is my capital
2-Nomadism culture isn't the main culture in it.
3-Baktra has a few Eastern Greek buildings
4-Baktra has a Hellenistic Polis
5-I set Baktra to an Allied Oligraphic city.

Any help would be deeply appreciated here.
