Answer: Railroad
Native American tribes had already been struggling for decades before the construction of a railroad began to be planned. However, the railroad was a catastrophic event for the Natives' way of life. The railroad forever altered the landscape of their traditional land, as well as caused the disappearance of wild game, such as bison. This was particularly destructive to the Plains people, who depended on the bison for nearly all of their needs.
The railroad also increased conflict between the Native people and the colonizers. It allowed white settlers to move to areas originally only inhabited by Native tribes, causing land disputes, deaths and displacement.
The Sugar Act, also known as the American Revenue Act or the American Duties Act, was a revenue-raising act passed by the Parliament of Great Britain on 5 April 1764.[1] The preamble to the act stated: "it is expedient that new provisions and regulations should be established for improving the revenue of this Kingdom ... and ... it is just and necessary that a revenue should be raised ... for defraying the expenses of defending, protecting, and securing the same."[2] The earlier Molasses Act 1733, which had imposed a tax of six pence per gallon of molasses, had never been effectively collected due to colonial evasion. By reducing the rate by half and increasing measures to enforce the tax, the British hoped that the tax would actually be collected.[3] These incidents increased the colonists' concerns about the intent of the British Parliament and helped the growing movement that became the American Revolution.[4] ( THIS IS FROM WIKIPEDIA)
