The 13th amendment abolished slavery, the 14th amendment gave citizenship to anybody born in the U.S., and the 15th amendment gave voting rights to everyone, regardless of race, gender, and ethnicity. How? Well, see below for an explanation!
The 13th Amendment, established completely in December 6, 1865, was an amendment that arguably abolished slavery and any form of involuntary servitude in the United States of America. This occurred under Abraham Lincoln’s administration, and was used as a gradual attempt at slavery vanquishment. The 14th amendment, established completely on July 9, 1868, was a newly ordered conduct allowing anybody citizenship who was born in the U.S.. Similar to the 13th amendment, this was an attempt at more freedom for people living in the U.S.. The 15th amendment, established completely on February 3, 1870, was an amendment in which everybody earned voting rights. This ratification was very crucial to the United States because many people had different opinions and biases on whether certain people should vote. Because the U.S. was very discriminatory at this time not only toward blacks, but toward women as well, this amendment sparked controversy throughout the South and led to gradual secession in states that would later form the Confederate States of America.

The First Europeans. The first Europeans to arrive in North America -- at least the first for whom there is solid evidence -- were Norse, traveling west from Greenland, where Erik the Red had founded a settlement around the year 985.
They moved around (though the cowboys were herding cattle, whereas the Native Americans were following the buffalo). They cared for the cattle (eg by bog-riding and from line-camps) in a way similar to the way Native American dog-soldiers cared for the buffalo.
