I can name a few: Slavery, Civil War, World War 1 and WW2, Industrial Revolution, 9/11, Obama being the first black president.
<span>Mixteca Culture, was an Amerindian town of Mesoamerica of Otomangueana linguistic family that inhabited the present Mexican states of Oaxaca, Guerrero and Puebla, in the called Mixteca region. The Mixtec civilization flourished in southern Mexico between the centuries (XV-II BC) and came to an end in the early sixteenth century AD when Europeans landed in America. The Mixtecas were the most famous artisans of pre-Columbian Mexico, their works in stone and in different metals were never surpassed in the region.

Communications: In 1900, there were not many technological devices that allowed for speedy communication. In 2000, there were emails,allowing for instantaenous sending of messages across the internet.

Government:In 1900, many rights and laws that were present in 2000 did not exist. It was from 1900 on that people started fighting for more rights. We had the suffragettes fighting for the right to vote,and thanks to that political fighting done in the early 1900's, they were able to achive their goals. During the 1900's the government of the United States underwent a progressive revolution, bringing on a lot of change on how things were done.
