Chola village administration was highly organized, with autonomous village assemblies like the 'ur' and 'nadu'. The 'ur' was a general assembly of all villagers, while the 'nadu' was a larger territorial unit comprising several villages. These assemblies managed local affairs, including land revenue collection, maintenance of irrigation tanks and canals, settling disputes, and administering justice. They also looked after temple administration and the welfare of the community, demonstrating a sophisticated system of self-governance under the Chola kings.
