Question

what makes india a federal country?

Answer 1

India is a federal country as power is shared between union and state government by making lists. Every state has its state government.

Answer 2

In India there have various states so that the power couldn't be control by the single government. Hence, we need a government which would share power with central government. The federation helps to enjoy the power on different tier of government. Every tiers of government have separate jurisdiction which makes easier to deal with laws.

The Indian Government clearly provided threefold distribution of legislative powers between union government and state government which contains three lists:-

Union list
State list
Concurrent list
