History

Social science (not often rendered in the plural as the social sciences) is one of the branches of science, devoted to the study of societies and the relationships among members within those societies. The term was formerly used to refer to the field of sociology, the original "science of society", established in the 18th century. It now encompasses a wide array of additional academic disciplines, including anthropology, archaeology, economics, geography, history, linguistics, management, communication studies, psychology, culturology, and political science.

The majority of positivist social scientists use methods resembling those used in the natural sciences as tools for understanding societies, and so define science in its stricter modern sense. Speculative social scientists, otherwise known as interpretivist scientists, by contrast, may use social critique or symbolic interpretation rather than constructing empirically falsifiable theories, and thus treat science in its broader sense. In modern academic practice, researchers are often eclectic, using multiple methodologies (combining both quantitative and qualitative research). To gain a deeper understanding of complex human behavior in digital environments, social science disciplines have increasingly integrated interdisciplinary approaches, big data, and computational tools. The term social research has also acquired a degree of autonomy as practitioners from various disciplines share similar goals and methods.

Maritime history is the study of human interaction with and activity at sea. It covers a broad thematic element of history that often uses a global approach, although national and regional histories remain predominant. As an academic subject, it often crosses the boundaries of standard disciplines, focusing on understanding humankind's various relationships to the oceans, seas, and major waterways of the globe. Nautical history records and interprets past events involving ships, shipping, navigation, and seafarers.

Maritime history is the broad overarching subject that includes fishing, whaling, international maritime law, naval history, the history of ships, ship design, shipbuilding, the history of navigation, the history of the various maritime-related sciences (oceanography, cartography, hydrography, etc.), sea exploration, maritime economics and trade, shipping, yachting, seaside resorts, the history of lighthouses and aids to navigation, maritime themes in literature, maritime themes in art, the social history of sailors and passengers and sea-related communities. There are a number of approaches to the field, sometimes divided into two broad categories: Traditionalists, who seek to engage a small audience of other academics, and Utilitarians, who seek to influence policy makers and a wider audience.

Territories of the United States are subnational geographical and political areas governed as administrative divisions and dependent territories under the sovereignty of the United States. Despite all being subject to the constitutional and territorial jurisdiction of the U.S. federal government, territories differ from states and Indian reservations in that they are not inherently sovereign. While states have dual sovereignty and Native American tribes have tribal sovereignty in relation to the federal government, the self-governing powers of territories ultimately derive from the U.S. Congress, as per the Territorial Clause in Article IV of the U.S. Constitution. Territories are classified as "organized" or "unorganized" depending on whether they operate under an organic act, and "incorporated" or "unincorporated" depending on whether the U.S. Constitution applies fully or partially to them. As areas belonging to, but not integral parts of, the U.S., territories are their own distinct nations centered around a collective identity based on their land, history, ethnicity, culture, and language.

All territories of the U.S. are insular areas. The U.S. has sovereignty over three archipelagos or islands in the Caribbean Sea and eleven in the Pacific Ocean. Five territories (American Samoa, Guam, the Northern Mariana Islands, Puerto Rico, and the United States Virgin Islands) are permanently inhabited, unincorporated territories; the other nine are small islands, atolls, and reefs with no native (or permanent) population. Of the 14, only one is classified as an incorporated territory (Palmyra Atoll). Two additional territories (Bajo Nuevo Bank and Serranilla Bank) are claimed by the U.S. but administered by Colombia. Historically, territories were created to administer newly acquired land, and most eventually attained statehood. The most recent territory to become a U.S. state was Hawaii on August 21, 1959.

Nationalism is an ideology or movement that holds that the nation should be congruent with the state. As a movement, it presupposes the existence and tends to promote the interests of a particular nation, especially with the aim of gaining and maintaining its sovereignty (self-determination) over its perceived homeland to create a nation-state. It holds that the nation should govern itself, free from outside interference (self-governance), that a nation is a natural and ideal basis for a polity, and that the nation is the only rightful source of political power. It further aims to build and maintain a single national identity, based on a combination of shared social characteristics such as culture, ethnicity, homeland, language, politics (or government), religion, traditions or belief in a shared singular history, and to promote national unity or solidarity. There are various definitions of a "nation", which leads to different types of nationalism. The two main divergent forms are ethnic nationalism and civic nationalism.

The moral value of nationalism, the relationship between nationalism and patriotism, and the compatibility of nationalism and cosmopolitanism are all subjects of philosophical debate. Nationalism can be combined with diverse political goals and ideologies such as conservatism (national conservatism and right-wing populism) or socialism (left-wing nationalism).

Colonialism's emphasis on imperialism, land dispossession, resource extraction, and cultural destruction frequently resulted in genocidal practices aimed at attacking Indigenous peoples and existing populations as a means to attain colonial goals. According to historian Patrick Wolfe, "[t]he question of genocide is never far from discussions of settler colonialism." Historians have commented that although colonialism does not necessarily directly involve genocide, research suggests that the two share a connection.

States have practised colonialism during various periods in history, even during progressive eras such as the Enlightenment. During the Enlightenment, a period in the history of 17th- and 18th-century Europe which was marked by some progressive reforms, natural social hierarchies were reinforced. Europeans who were educated, white, and native-born were considered high-class, whereas less-educated, non-European people were considered low-class. These "natural" hierarchies were reinforced by progressives such as the Marquis de Condorcet (1743-1794), a French mathematician, who believed that slaves were savages due to their lack of modern practices, despite the fact that he advocated the abolition of slavery. The colonization process usually starts by attacking the homes of its targets. Typically, the people who are subjected to colonizing practices are portrayed as lacking modernity, because they and the colonialists do not have the same level of education or technology.

Law is a set of rules that are created and are enforceable by social or governmental institutions to regulate behavior, with its precise definition a matter of longstanding debate. It has been variously described as a science and as the art of justice. State-enforced laws can be made by a legislature, resulting in statutes; by the executive through decrees and regulations; or by judges' decisions, which form precedent in common law jurisdictions. An autocrat may exercise those functions within their realm. The creation of laws themselves may be influenced by a constitution, written or tacit, and the rights encoded therein. The law shapes politics, economics, history and society in various ways and also serves as a mediator of relations between people.

Legal systems vary between jurisdictions, with their differences analysed in comparative law. In civil law jurisdictions, a legislature or other central body codifies and consolidates the law. In common law systems, judges may make binding case law through precedent, although on occasion this may be overturned by a higher court or the legislature. Religious law is in use in some religious communities and states, and has historically influenced secular law.

Humans, scientifically known as Homo sapiens, are primates that belong to the biological family of great apes and are characterized by hairlessness, bipedality, and high intelligence. Humans have large brains compared to body size, enabling more advanced cognitive skills that facilitate successful adaptation to varied environments, development of sophisticated tools, and formation of complex social structures and civilizations.

Humans are highly social, with individual humans tending to belong to a multi-layered network of distinct social groups – from families and peer groups to corporations and political states. As such, social interactions between humans have established a wide variety of values, social norms, languages, and traditions (collectively termed institutions), each of which bolsters human society. Humans are also highly curious: the desire to understand and influence phenomena has motivated humanity's development of science, technology, philosophy, mythology, religion, and other frameworks of knowledge; humans also study themselves through such domains as anthropology, social science, history, psychology, and medicine. As of 2025, there are estimated to be more than 8 billion living humans.

Western Thrace (Greek: Δυτική Θράκη, IPA: [ðitiˈci ˈθɾaci]), also known as Greek Thrace or Aegean Thrace, is a geographical and historical region of Greece, between the Nestos and Evros rivers in the northeast of the country; East Thrace, which lies east of the river Evros, forms the European part of Turkey, and the area to the north, in Bulgaria, is known as Northern Thrace.

Inhabited since Paleolithic times, it has been under the political, cultural and linguistic influence of the Greek world since the classical era; Greeks from the Aegean islands extensively colonized the region (especially the coastal part) and built prosperous cities such as Abdera (home of Democritus, the 5th-century BC philosopher who developed an atomic particle theory, and of Protagoras, a leading sophist) and Sale (near present-day Alexandroupolis). Under the Byzantine Empire, Western Thrace benefited from its position close to the imperial heartland and became a center of medieval Greek commerce and culture; later, under the Ottoman Empire, a number of Muslims settled there, marking the birth of the Muslim minority of Greece.

Material culture is culture manifested by the physical objects and architecture of a society. The term is primarily used in archaeology and anthropology, but is also of interest to sociology, geography and history. The field considers artifacts in relation to their specific cultural and historic contexts, communities and belief systems. It includes the usage, consumption, creation and trade of objects as well as the behaviors, norms and rituals that the objects create or take part in.

Material culture is contrasted with symbolic culture or non-material culture, which include non-material symbols, beliefs and social constructs. However, some scholars include in material culture other intangible phenomena like sound, smell and events, while some even consider it to include language and media. Material culture can be described as any object that humans use to survive, define social relationships, represent facets of identity, or benefit peoples' state of mind, social, or economic standing.
