Citizenship 520 BCE – 2030 CE
From the Greek polis to global belonging — the changing story of who counts as a member and what that entitles.
- 450 BCE
Pericles' citizenship law, Athens. Athens restricts citizenship to those with two Athenian parents, tightly guarding the privileges of assembly, office and land. Citizenship is an exclusive status of active self-rule for a minority — excluding women, slaves and resident foreigners — but for the first time defines the citizen as ruler and ruled in turn.
- 340 BCE
Aristotle, Politics. Aristotle defines the citizen not by residence but by the right to share in ruling and being ruled — in judging and holding office. To be a citizen is to participate in the common life of the polis, making political activity the essence of a fully human existence.
- 90 BCE
The Social War & Roman civitas. After Rome's Italian allies revolt, citizenship is extended across the peninsula, transforming it from a face-to-face membership into a portable legal status. Roman citizenship carries rights — to trial, appeal, contract and marriage — that travel with a person far from any single city.
- 212 CE
Edict of Caracalla. The Constitutio Antoniniana grants Roman citizenship to nearly all free inhabitants of the empire. Citizenship is decoupled from a particular city or people and becomes a near-universal imperial status — vast in reach but thin in the political participation the Greeks had prized.
- 1200 CE
The medieval commune. In the self-governing towns of medieval Europe, burgher status confers freedom, trade rights and a share in urban government — 'city air makes you free', as the saying went. Citizenship revives as membership in a chartered community, a seedbed of later civic and republican ideals.
- 1762 CE
Rousseau, The Social Contract. Rousseau revives the classical citizen as co-author of the law, a member of the sovereign people rather than a mere subject. Citizenship becomes an active, moral bond of shared self-rule — the ideal that the coming revolutions will proclaim against monarchy.
- 1789 CE
French Revolution. The Revolution replaces the king's subjects with equal citizens of the nation, bearers of rights and members of a sovereign people. 'Citoyen' becomes a title of dignity and equality, binding citizenship to nationhood — the template for the modern nation-state's membership.
- 1868 CE
U.S. Fourteenth Amendment. After the Civil War, the Fourteenth Amendment makes all persons born or naturalised in the United States citizens, guaranteeing them equal protection of the laws. It ties citizenship to birthplace and to a promise of equality, overturning a slaveholding order that had denied it.
- 1950 CE
T. H. Marshall, Citizenship and Social Class. Marshall traces citizenship's expansion in three waves — civil rights, then political rights, then social rights to welfare and security. Full citizenship, he argues, requires a social minimum, tying membership to education, health and a decent standard of life in the modern state.
- 1992 CE
Maastricht & EU citizenship. The Maastricht Treaty creates citizenship of the European Union, granting rights to move, reside and vote across member states without replacing national citizenship. For the first time citizenship layers above the nation-state, opening debates over post-national, dual and even global belonging.
The milestones
451 BCE
Pericles' citizenship law, Athens
Citizenship by birth and blood
Athens restricts citizenship to those with two Athenian parents, tightly guarding the privileges of assembly, office and land. Citizenship is an exclusive status of active self-rule for a minority — excluding women, slaves and resident foreigners — but for the first time defines the citizen as ruler and ruled in turn.
c. 340 BCE
Aristotle, Politics
The citizen defined
Aristotle defines the citizen not by residence but by the right to share in ruling and being ruled — in judging and holding office. To be a citizen is to participate in the common life of the polis, making political activity the essence of a fully human existence.
90 BCE
The Social War & Roman civitas
Citizenship as a legal status
After Rome's Italian allies revolt, citizenship is extended across the peninsula, transforming it from a face-to-face membership into a portable legal status. Roman citizenship carries rights — to trial, appeal, contract and marriage — that travel with a person far from any single city.
212 CE
Edict of Caracalla
Citizenship for (almost) all
The Constitutio Antoniniana grants Roman citizenship to nearly all free inhabitants of the empire. Citizenship is decoupled from a particular city or people and becomes a near-universal imperial status — vast in reach but thin in the political participation the Greeks had prized.

The medieval commune
'City air makes you free'

1762
Rousseau, The Social Contract
The citizen as sovereign
Rousseau revives the classical citizen as co-author of the law, a member of the sovereign people rather than a mere subject. Citizenship becomes an active, moral bond of shared self-rule — the ideal that the coming revolutions will proclaim against monarchy.
1789
French Revolution
From subject to citizen
The Revolution replaces the king's subjects with equal citizens of the nation, bearers of rights and members of a sovereign people. 'Citoyen' becomes a title of dignity and equality, binding citizenship to nationhood — the template for the modern nation-state's membership.
1868
U.S. Fourteenth Amendment
Birthright and equal protection
After the Civil War, the Fourteenth Amendment makes all persons born or naturalised in the United States citizens, guaranteeing them equal protection of the laws. It ties citizenship to birthplace and to a promise of equality, overturning a slaveholding order that had denied it.
1950
T. H. Marshall, Citizenship and Social Class
Civil, political, social citizenship
Marshall traces citizenship's expansion in three waves — civil rights, then political rights, then social rights to welfare and security. Full citizenship, he argues, requires a social minimum, tying membership to education, health and a decent standard of life in the modern state.

Maastricht & EU citizenship
Citizenship beyond the nation
The Maastricht Treaty creates citizenship of the European Union, granting rights to move, reside and vote across member states without replacing national citizenship. For the first time citizenship layers above the nation-state, opening debates over post-national, dual and even global belonging.
