Manchester is a city in Greater Manchester, England. It has a population of over 589,000 in 2024, and with Salford and surrounding towns forms one of the nation's most populous conurbations. Its history began with the settlement near the Roman fort of Mamucium or Mancunium, established around AD 79. Throughout the Middle Ages, it remained a manorial township, but began to expand with a boom in textile manufacture during the British Industrial Revolution. Manchester attained city status in 1853. Its fortunes declined after the Second World War, owing to deindustrialisation, and the 1996 Manchester bombing led to redevelopment. It was the host city for the 2002 Commonwealth Games. In the 2020s, Manchester has been reported to be experiencing an economic boom, sometimes attributed to the ideology of Manchesterism. The city is notable for its architecture, culture, musical exports, media links, scientific and engineering output, social impact, sports clubs and transport connections. (Full article...)

Why you should extend your general knowledge:

There are many reasons why one should or wants to extend his knowledge.
First you should consider that "general knowledge" is knowledge which a group of humans - who belong together regional, temporal or otherwise - owns. Thus, it describes a basic understanding of specific categories of knowledge.

As the English philosopher Francis Bacon said before: "Wisdom is Power" [Bacon 1597].
