Industry is generally the manufacturing of goods involved in the manufacturing of raw materials into goods and products.
Early industries involved manufacturing goods for trade, including weapons, clothing, pottery. In medieval Europe, industry became dominated by the guilds in cities and towns, who mutual support for the member's interests, and maintained standards of workmanship and ethical conduct.
The industrial revolution led to the development of factories for large-scale production, which helped to change society with increased work for more people and wages. A mass migration from the countryside resulted in large towns and citys expanding.
More and more industry is going aboard changing our once industrialized nation toward a post-industrial society. This has increased the service sector at the expense of manufacturing which has resulted in derelict industrial areas in the large towns and citys, increased unemployment resulting in more people becoming impoverished
