And neither would the British.The people as a whole wouldn't side with the princes against Congress.
They'd simply get sidelined. The Princes, as a body, didn't have much allegiance directed personally to them. Congress was capable of taking control of the Princely States with or without the agreement of the Princes- it would mean a lot more turmoil but it would be doable. The people as a whole wouldn't side with the princes against Congress.
What do you base that on? Didnt people just want to get rid of the British?
By Congress you mean the congress party?
