To restrict monopolies and to encourage economic competition.

The Sherman Anti-trust Act was an economic policy put into place to promote competition in the economy. The law prevented restrictions to trade between states or foreign trade as well as restricted monopolies.

The Sherman Ant-trust Act was put into place to prevent the monopolies occurring as a result of corporate buy outs and corrupt practices by the industrial titans. Men like Rockefeller, Carnegie, and JP Morgan were buying out small businesses both within their industry and across industries. The power of these men allowed them to set prices wherever they wanted and many smaller businesses and dependent industries suffered due to monopolies.

this act gave the federal government the power to relocate any native in the east to territory west of the mississippi river.
