The correct answer is - trade.
The Sumerians engaged in trade with their move of exchanging their surplus food for materials like the copper that they needed to develop their weapons and thus their army forces. This was a very smart move from their side because they managed to use the resource they had in abundance but was scarce in the other surrounding areas so that they take what they need to become stronger and pretty much defend more efficiently from the same people they were engaging in trade with.
They all treated them poorly because they wanted their land.
Answer:
Founded in 1865, the Ku Klux Klan (KKK) extended into almost every southern state by 1870 and became a vehicle for white southern resistance to the Republican Party’s Reconstruction-era policies aimed at establishing political and economic equality for Black Americans. Its members waged an underground campaign of intimidation and violence directed at white and Black Republican leaders. Though Congress passed legislation designed to curb Klan terrorism, the organization saw its primary goal–the reestablishment of white supremacy–fulfilled through Democratic victories in state legislatures across the South in the 1870s.
After a period of decline, white Protestant nativist groups revived the Klan in the early 20th century, burning crosses and staging rallies, parades and marches denouncing immigrants, Catholics, Jews, African Americans and organized labor. The civil rights movement of the 1960s also saw a surge of Ku Klux Klan activity, including bombings of Black schools and churches and violence against Black and white activists in the South.
Founding of the Ku Klux Klan
A group including many former Confederate veterans founded the first branch of the Ku Klux Klan as a social club in Pulaski, Tennessee, in 1865. The first two words of the organization’s name supposedly derived from the Greek word “kyklos,” meaning circle. In the summer of 1867, local branches of the Klan met in a general organizing convention and established what they called an “Invisible Empire of the South.” Leading Confederate general Nathan Bedford Forrest was chosen as the first leader, or “grand wizard,” of the Klan; he presided over a hierarchy of grand dragons, grand titans and grand cyclopses.
