Entities in languageLanguage is a structured system of communication that consists of grammar and vocabulary. It is the primary means by which humans convey meaning, both in spoken and written forms, and may also be conveyed through sign languages. The vast majority of human languages have developed writing systems that allow for the recording and preservation of the sounds or signs of language. Human language is characterized by its cultural and historical diversity, with significant variations observed between cultures and across time.
Contemporary historyContemporary history, in English-language historiography, is a subset of modern history that describes the historical period from approximately 1945 to the present. Contemporary history is either a subset of the late modern period, or it is one of the three major subsets of modern history, alongside the early modern period and the late modern period. In the social sciences, contemporary history is also continuous with, and related to, the rise of postmodernity.
Entities in state politicsA sovereign state is a state that has the highest authority over a territory. International law defines sovereign states as having a permanent population, defined territory, a government not under another, and the capacity to interact with other sovereign states. It is also commonly understood that a sovereign state is independent. According to the declarative theory of statehood, a sovereign state can exist without being recognised by other sovereign states.
Regional geographyRegional geography is a major branch of geography. It focuses on the interaction of different cultural and natural geofactors in a specific land or landscape, while its counterpart, systematic geography, concentrates on a specific geofactor at the global level. Attention is paid to unique characteristics of a particular region such as natural elements, human elements, and regionalization which covers the techniques of delineating space into regions.
Global citiesA megalopolis (ˌmɛgəˈlɒpəlɪs) or a supercity, also called a megaregion, is a group of metropolitan areas which are perceived as a continuous urban area through common systems of transport, economy, resources, ecology, and so on. They are integrated enough that coordinating policy is valuable, although the constituent metropolises keep their individual identities. The megalopolis concept has become highly influential as it introduced a new, larger scale thinking about urban patterns and growth.
Topics in classical antiquityClassical antiquity, also known as the classical era, classical period, classical age, or simply antiquity, is the period of cultural history between the 8th century BC and the 8th century AD centered on the Mediterranean Sea, comprising the interlocking civilizations of ancient Greece and ancient Rome known as the Greco-Roman world. It is the period in which both Greek and Roman societies flourished and wielded huge influence throughout much of Europe, North Africa, and West Asia.
Early modern periodThe early modern period of modern history spans the period after the Late Middle Ages of the post-classical era (1400–1500) to the beginning of the Age of Revolutions (1800). Although the chronological limits of this period are open to debate, the timeframe is variously demarcated by historians as beginning with the fall of Constantinople in 1453, the Renaissance period in Europe and Timurid Central Asia, the end of the Crusades, the Age of Discovery (especially the voyages of Christopher Columbus beginning in 1492 but also Vasco da Gama's discovery of the sea route to India in 1498), and ending around the French Revolution in 1789, or Napoleon's rise to power.
Topics in climateClimate is the long-term weather pattern in a region, typically averaged over 30 years. More rigorously, it is the mean and variability of meteorological variables over a time spanning from months to millions of years. Some of the meteorological variables that are commonly measured are temperature, humidity, atmospheric pressure, wind, and precipitation. In a broader sense, climate is the state of the components of the climate system, including the atmosphere, hydrosphere, cryosphere, lithosphere and biosphere and the interactions between them.
Geography of AsiaGeography of Asia reviews geographical concepts of classifying Asia, the central and eastern part of Eurasia, comprising approximately fifty countries. Definition and boundaries of Asia The land mass of Asia is not the sum of the land masses of each of its regions, which have been defined independently of the whole. For example, the borders of Central Asia and the Middle East depend on who is defining them and for what purpose.
Abrahamic religionsThe Abrahamic religions are a group of religions centered around the worship of the God of Abraham. Abraham, a Hebrew patriarch, is extensively mentioned throughout the Abrahamic religious scriptures of the Quran, and the Hebrew and Christian Bibles. Jewish tradition claims that the Twelve Tribes of Israel are descended from Abraham through his son Isaac and grandson Jacob, whose sons formed the nation of the Israelites in Canaan (or the Land of Israel); Islamic tradition claims that twelve Arab tribes known as the Ishmaelites are descended from Abraham through his son Ishmael in the Arabian Peninsula.
