ancient Rome and the Rzeczpospolita of Poland-Lithuania which finds echoes in the modern-day republic. The concept of temple states centred on religious shrines occurs in some discussions of the ancient world. Relatively small city-states, once a relatively common and often successful form of polity, have become rarer and comparatively less prominent in modern times. Modern-day independent city-states include Vatican City, Monaco, and Singapore. Other city-states survive as federated states, like the present day German city-states, or as otherwise autonomous entities with limited sovereignty, like Hong Kong, Gibraltar and Ceuta. To some extent, urban secession, the creation of a new city-state (sovereign or federated), continues to be discussed in the early 21st century in cities such as London.

A nation-state refers to a situation where a single ethnicity is associated with a specific state. State and civil society In the classical thought, the state was identified with both political society and civil society as a form of political community, while the modern thought distinguished the nation state as a political society from civil society as a form of economic society. Thus in the modern thought the state is contrasted with civil society. Antonio Gramsci believed that civil society is the primary locus of political activity because it is where all forms of "identity formation, ideological struggle, the activities of intellectuals, and the construction of hegemony take place." and that civil society was the nexus connecting the economic and political sphere. Arising out of the collective actions of civil society is what Gramsci calls "political society", which Gramsci differentiates from the notion of the state as a polity. He stated that politics was
