A sovereign state is a nation, country, etc. It is sovereign, which means it is self-governing/independent and no power is above it. India is a sovereign state, or country.

A state can also be a political division of a country, in which it acts as a somewhat self-governing region, but is not sovereign and ultimately falls under the country's national government. Indiana is such a state; India is not.
