To be a citizen means to be a recognized member of a political community, typically a nation or state, who owes allegiance to that state and is entitled to its protection. Citizenship entails rights, such as the right to vote, hold public office, and access certain legal protections, as well as duties like obeying laws, paying taxes, and defending the country if necessary. Citizenship is both a legal status and a participatory membership in a community with reciprocal obligations between the individual and the state. It also includes a sense of belonging and loyalty to a collective political community. In summary:

• A citizen is a legally recognized member of a state or nation.
