Merger (politics) in the context of "Hollywood, Los Angeles"

The unification of the Georgian realm (Georgian: ქართული სახელმწიფოს გაერთიანება, romanized: kartuli sakhelmts'ipos gaertianeba) was the 10th-century political movement that resulted in the consolidation of various Georgian crowns into a single realm with centralized government in 1008, the Kingdom of Georgia, or Sakartvelo. It was originally initiated by the powerful local aristocracy of the eristavs, due to centuries-long power struggles and aggressive wars of succession between the Georgian monarchs, arising from their independent ruling traditions of classical antiquity and their Hellenistic-era monarchical establishments in Colchis and Iberia.

The initiative was supported by David III the Great of the Bagrationi dynasty, the most powerful ruler in the Caucasus at the time, who would put prince royal Bagrat, his kin and foster-son, on the Iberian throne, who would eventually be crowned King of all-Georgia. David's Bagratid successors would become the champions of national unification, just like the Rurikids or the Capetians, but despite their enthusiasm, some of the Georgian polities that had been targeted for unification did not join the unification freely and would actively fight against it throughout this process, mostly seeking help and support from the Byzantine Empire and the Abbasid Caliphate. Even though the 1008 unification of the realm would unite most of western and central Georgian lands, the process would continue to the east, and eventually reach its total completion under King David IV the Builder. This unprecedented political unification of lands and the meteoric rise of Bagrationi power would inaugurate the Georgian Golden Age and creation of the only medieval pan-Caucasian empire, attaining its greatest geographical extent and dominating the entire Caucasus in the 11th, 12th and 13th centuries.

The City of Greater New York was the consolidation of the City of New Yorkwith Brooklyn, western Queens County, and Staten Island, which took effect on January 1, 1898. New York had already annexed the Bronx (west of the Bronx River in 1874, east of the Bronx River in 1895), so the consolidated city sprawled across five counties, which became the five Boroughs of modern New York. Eastern Queens County was excluded and later became Nassau County.

Toronto is the most populous city in Canada and the capital city of the Canadian province of Ontario. With a population of 2,794,356 in 2021, it is the fourth-most populous city in North America. The city is the anchor of the Golden Horseshoe, an urban agglomeration of 9,765,188 people (as of 2021) surrounding the western end of Lake Ontario, while the Greater Toronto Area proper had a 2021 population of 6,712,341. As of 2024, the Golden Horseshoe had an estimated population of 11,139,265 people while the census metropolitan area had an estimated population of 7,106,379. Toronto is an international centre of business, finance, arts, sports, and culture, and is recognized as one of the most multicultural and cosmopolitan cities in the world.

Indigenous peoples have inhabited the Toronto area, located on a broad sloping plateau interspersed with rivers, deep ravines, and urban forest, for more than 10,000 years. After the broadly disputed Toronto Purchase, when the Mississauga surrendered the area to the British Crown, the British established the town of York in 1793 and later designated it as the capital of Upper Canada. During the War of 1812, the town was captured by the United States after they won the Battle of York in 1813, after which it was largely burned down and plundered by the American troops. York was renamed and incorporated in 1834 as the City of Toronto. It was designated as the capital of the province of Ontario in 1867 during Canadian Confederation. The city proper has since expanded past its original limits through both annexation and amalgamation to its current area of 630.2 km (243.3 sq mi).

In United States local government, a consolidated city-county (see below for alternative terms) is formed when one or more cities and their surrounding county (parish in Louisiana, borough in Alaska) merge into one unified jurisdiction. As such it is a type of unitary authority that has the governmental powers of both a municipal corporation and a county.

A consolidated city-county is different from an independent city, although the latter may result from consolidation of a city and a county and may also have the same powers as a consolidated city-county. An independent city is a city not deemed by its state to be located within the boundary of any county and considered a primary administrative division of its state. A consolidated city-county differs from an independent city in that the city and county both nominally exist, although they have a consolidated government, whereas in an independent city, the county does not even nominally exist. Furthermore, a consolidated city-county may still contain independent municipalities maintaining some governmental powers that did not merge with the rest of the county.

The amalgamation of Toronto was the creation of the city limits of Toronto, Ontario, Canada after amalgamating, annexing, and merging with surrounding municipalities since the 18th century. The most recent occurrence of amalgamation was in 1998, which dissolved the federation of Metropolitan Toronto and its constituent municipalities, and created the current "megacity" of Toronto.

Since 1 January 2023, there are 342 regular municipalities (Dutch: gemeenten [ɣəˈmeːntə(n)] ; sing. gemeente [xəˈmeːntə] ) and three special municipalities (Dutch: bijzondere gemeenten [biˈzɔndərə -]) in the Netherlands. The latter is the status of three of the six island territories that make up the Dutch Caribbean. Municipalities are the second-level administrative division, or public bodies (Dutch: openbare lichamen), in the Netherlands and are subdivisions of their respective provinces. Their duties are delegated to them by the central government and they are ruled by a municipal council that is elected every four years. Municipal mergers have reduced the total number of municipalities by two-thirds since the first official boundaries were created in the mid 19th century. Municipalities themselves are informally subdivided into districts and neighbourhoods for administrative and statistical purposes.

These municipalities come in a wide range of sizes, Westervoort is the smallest with a land area of 7.01 km (2.71 sq mi) and Súdwest-Fryslân the largest with a land area of 522.7 km (201.8 sq mi). Schiermonnikoog is both the least populated, with 972 people, and the least densely populated municipality at 23/km (60/sq mi). Amsterdam has the highest population with 931,298 residents as of January 2024, whereas The Hague is the most densely populated with a density of 6,868/km (17,790/sq mi).
