State (polity)

A state is a political entity that regulates a population within a specific territory. It acts as a central organization that imposes rules on its people. Most modern states use a government to function. A government is the specific organization given authority to act for the state. It is important to distinguish a state from a nation. A nation is a group defined by shared culture or history. A state is a political-legal abstraction with clear geographic boundaries.

Scholars have different ways of defining what a state actually is. Sociologist Max Weber provided one of the most famous definitions. He described the state as a human community that claims a monopoly on the legitimate use of physical force. This means only the state has the legal right to use violence to maintain order. Other thinkers, like Walter Scheidel, focus on the institutions that rule. He notes that states must have centralized institutions to back up their rules with force. These institutions create a clear distinction between those who rule and those who are ruled.

States can take several different structural forms. A unitary state has a single, central power that manages everything. In contrast, a federal union divides power between a central government and smaller parts. In a federal system, these smaller parts are sometimes called states, provinces, or regions. These smaller units may have some sovereign attributes. However, they remain under the larger federation and lack full international capacity.

History shows that humans did not always live under states. For most of prehistory, people lived in stateless societies. The first states emerged approximately 5,500 years ago. As cities grew, societies became more stratified, meaning they developed social layers. This growth was often tied to climate and economic changes. Sometimes, territorial competition and insecurity forced people to centralize power for protection.

Different theories explain why states form and how they behave. The contractarian view suggests that people cooperate to avoid chaos. This idea implies that people agree to follow rules for mutual benefit. Another view, the predatory view, suggests a mismatch between people and the state. Charles Tilly offered a controversial perspective on this. He argued that states resemble organized crime or extortion rackets. He believed states sell protection from themselves to their citizens.

Charles Tilly also identified specific activities that define state-making. He listed seven essential minimal activities for a state. These include war-making to neutralize outside rivals and state-making to manage internal rivals. States also provide protection, extraction of resources, and adjudication of disputes. They also handle distribution of goods and the production of services. Tilly argued that war is a primary driver of state formation. He noted that in Europe, states became particularly prominent after 1490.

We can also compare states to the massive empires of the past. Historians like Josep Colomer note that empires were much larger than states. Empires often lacked fixed or permanent boundaries. They contained many diverse groups with overlapping jurisdictions. In contrast, a modern state seeks a monopoly of authority over a single territory. It aims for more control and homogenization within its borders.

To be recognized globally, states often follow specific criteria. The Montevideo Convention of 1933 established four key qualifications. A state must have a permanent population and a defined territory. It must also possess a government and the capacity to enter relations with other states. Today, the modern nation-state is the most common way the world is organized. The degree to which a state can govern determines if it is considered a "failed state."
