Question

Was the local self-government system under the cholas similar to the modern system of village Panchayats​

Answer 1

The Cholas believed in local self-government. In many of the villages, the administration was carried out not by the government officials but by the villagers themselves. These villages had three types of assemblies, namely the ur, the sabha and the nagaram.
So we can say the methodoly is same but the functionality is bit different.
