Disarticulation of guildas (leagues of teceles) and exploitation of the agricultural workers who migram for the cities; substitution of the artisan workshops for the plant. Directed technological development to the increase of the production. The precocidade with that the industrial process occurs in England must still to the stimulaton of two factors: the partner-cultural environment favorable to the commercial activities, and the great flow of capital destined to the mechanization of the production, what it stimulates the fast technological development; both derivatives of the interest of the aristocracy in participating of the production processes. It is in this point that the technological progress becomes preponderant: siderurgy is developed to take care of the increasing use of iron in the new maquinrios; the use of boilers and tubings of iron goes to lead to the great discovery that goes to revolutionize the production processes: the use of the vapor to put into motion the maquinrio. The substitution of the animal effort for the vapor entirely initiates a new age for the humanity; we are difficult for, today so accustomed to mechanization, to understand the picture of new possibilities that if opened. In 1870, for example, the capacity of the machines the vapor of England was of 4 million HP; to generate this with animal force 6 million horses would be necessary! From the dissemination of the use of machines the vapor the industrial production knows a jump fabuloso: The iron-gusa production polishes of 125.000 tons in 1796 p 2.700.000 of tons 50 years later. The coal consumption goes of 11 million tons in 1800 for 100 million in 1870. The productivity of the man increases more than in 100 times in little more than half century! Social changes Leo Huberman identify the evolution of the systems of production in four periods of training, the period between centuries XVI and XVIII: 1.Sistema familiar: production essentially to take care of the proper consumption; eventual commercialization of the excess. .
