The answer to the question: What is the name of the period that brought poverty and squalor to a large part of the population? is inside the article: Manchester has a notable place in the history of Marxism and left-wing politics; being the subject of Friedrich Engels' work The Condition of the Working Class in England in 1844; Engels spent much of his life in and around Manchester, and when Karl Marx visited Manchester, they met at Chetham's Library. The economics books Marx was reading at the time can be seen in the library, as can the window seat where Marx and Engels would meet. The first Trades Union Congress was held in Manchester (at the Mechanics' Institute, David Street), from 2 to 6 June 1868. Manchester was an important cradle of the Labour Party and the Suffragette Movement.At that time, it seemed a place in which anything could happennew industrial processes, new ways of thinking (the Manchester School, promoting free trade and laissez-faire), new classes or groups in society, new religious sects, and new forms of labour organisation. It attracted educated visitors from all parts of Britain and Europe. A saying capturing this sense of innovation survives today: "What Manchester does today, the rest of the world does tomorrow." Manchester's golden age was perhaps the last quarter of the 19th century. Many of the great public buildings (including Manchester Town Hall) date from then. The city's cosmopolitan atmosphere contributed to a vibrant culture, which included the Halle Orchestra. In 1889, when county councils were created in England, the municipal borough became a county borough with even greater autonomy. Although the Industrial Revolution brought wealth to the city, it also brought poverty and squalor to a large part of the population. Historian Simon Schama noted that "Manchester was the very best and the very worst taken to terrifying extremes, a new kind of city in the world; the chimneys of industrial suburbs greeting you with columns of smoke". An American visitor taken to Manchester's blackspots saw "wretched, defrauded, oppressed, crushed human nature, lying and bleeding fragments".The number of cotton mills in Manchester itself..., can you guess it ?
