A city is a human settlement of a substantial size. The term "city" has different meanings around the world and in some places the settlement can be very small. Even where the term is limited to larger settlements, there is no universally agreed definition of the lower numerical boundary for their size. In a more specific sense, a city can be defined as a permanent and densely populated place with administratively defined boundaries whose members work primarily on non-agricultural tasks. Cities generally have extensive systems for housing, transportation, sanitation, utilities, land use, production of goods, and communication. Their density facilitates interaction between people, government organizations, and businesses, sometimes benefiting different parties in the process, such as improving the efficiency of goods and service distribution.
Historically, city dwellers have been a small proportion of humanity overall, but following two centuries of unprecedented and rapid urbanization, more than half of the world population now lives in cities, which has had profound consequences for global sustainability. Present-day cities usually form the core of larger metropolitan areas and urban areas—creating numerous commuters traveling toward city centres for employment, entertainment, and education. However, in a world of intensifying globalization, all cities are to varying degrees also connected globally beyond these regions. This increased influence means that cities also have significant influences on global issues, such as sustainable development, climate change, and global health. Because of these major influences on global issues, the international community has prioritized investment in sustainable cities through Sustainable Development Goal 11. Due to the efficiency of transportation and the smaller land consumption, dense cities hold the potential to have a smaller ecological footprint per inhabitant than more sparsely populated areas. Therefore, compact cities are often referred to as a crucial element in fighting climate change. However, this concentration can also have some significant harmful effects, such as forming urban heat islands, concentrating pollution, and stressing water supplies and other resources.

Moscow is the capital and largest city of Russia, standing on the Moskva River in Central Russia. It has a population estimated at over 13 million residents within the city limits, over 19.1 million residents in the urban area, and over 21.5 million residents in its metropolitan area. The city covers an area of 2,511 square kilometers (970 mi2), while the urban area covers 5,891 square kilometers (2,275 mi2), and the metropolitan area covers over 26,000 square kilometers (10,000 mi2). Moscow is among the world's largest cities, being the most populous city entirely in Europe, the largest urban and metropolitan area in Europe, and the largest city by land area on the European continent.
First documented in 1147, Moscow became the capital of the Grand Principality of Moscow, which led the unification of the Russian lands in the 15th century and became the center of a unified state. Following the proclamation of the Tsardom of Russia in 1547, Moscow remained the political and economic center for most of its history. During the reign of Peter the Great, the Russian capital was moved to the newly founded city of Saint Petersburg in 1712, leading to a decline in Moscow's importance throughout the imperial period. Following the Russian Revolution and the establishment of the Russian SFSR, the capital was moved back to Moscow in 1918. The city later became the political center of the Soviet Union and experienced significant population growth throughout the Soviet period. In the aftermath of the dissolution of the Soviet Union, Moscow remained the capital city of the newly reconstituted Russian Federation and has experienced continued growth. (Full article...)

Tell Brak (Nagar, Nawar) was an ancient city in Syria; it is one of the earliest known cities in the world. Its remains constitute a tell located in the Upper Khabur region, near the modern village of Tell Brak, 50 kilometers north-east of Al-Hasaka city, Al-Hasakah Governorate. The city's original name is unknown. During the second half of the third millennium BC, the city was known as Nagar and later on, Nawar.
Starting as a small settlement in the seventh millennium BC, Tell Brak's urbanization began in the late 5th millennium BCE and evolved during the fourth millennium BC into one of the biggest cities in Upper Mesopotamia, and interacted with the cultures of southern Mesopotamia. The city shrank in size at the beginning of the third millennium BC with the end of Uruk period, before expanding again around 2600 BC, when it became known as Nagar, and was the capital of a regional kingdom that controlled the Khabur river valley. Nagar was destroyed around 2300 BC, and came under the rule of the Akkadian Empire, followed by a period of independence as a Hurrian city-state, before contracting at the beginning of the second millennium BC. Nagar prospered again by the 19th century BC, and came under the rule of different regional powers. In c. 1500 BC, Tell Brak was a center of Mitanni before being destroyed by Assyria around 1300 BC. The city never regained its former importance, remaining as a small settlement, and abandoned at some points of its history, until disappearing from records during the early Abbasid era.

An urban area is a human settlement with a high population density and an infrastructure of built environment. Urban areas originate through urbanization, and researchers categorize them as cities, towns, conurbations or suburbs. In urbanism, the term "urban area" contrasts to rural areas such as villages and hamlets. In urban sociology or urban anthropology, it often contrasts with natural environment.
The development of earlier predecessors of modern urban areas during the urban revolution of the 4th millennium BCE led to the formation of human civilization and ultimately to modern urban planning, which along with other human activities such as exploitation of natural resources has led to a human impact on the environment.
