The main reason for the industrial revolution in the Northern States of America was the development of the railways. The railways helped in linking different places and in the quick transport of men and material. Another reason for the industrial revolution there was the manufactured machines. With this large scale, farming was made easy.
With the development in industry, industrial cities began to grow in the USA and Canada. The number of factories increased manyfold. In the 1860s, the economy of the US was undeveloped. But by 1890, it became a powerful industrial nation.
There was also large scale agriculture. Vast areas were cleared for cultivation. By 1880, the bison (wild bualoes) faced extinction. With this their hunting by the indigenes came to an end. By 1892, the European settlements were almost complete throughout the USA. The region between the Pacic and the Atlantic was divided into States. In a short time, the USA established its colonies in Hawaii and the Philippines. Thus the US became an imperial power.
