The Treaty of Guadalupe-Hidalgo was the treaty that formally concluded the Mexican War (1846–1848) between the United States and Mexico. The main agreement established was the "Mexican Cession," the region that Mexico was forced to cede to the United States. It was agreed that Mexican citizens in that area would be considered as legal U.S. citizens unless they vacated the area or filed as Mexican citizens for that first year. In practice, this meant that many people were separated from their families, and a long process of discrimination against Mexican Americans started.
In 727 BCE, Kush took control of Egypt and ruled until the Assyrians arrived. The empire began to weaken after Rome conquered Egypt and eventually collapsed sometime in the 300s CE.
