Sherman used "absolute warfare" I believe. He is most famous for his March to the Sea in which he marched his men through Georgia and literally destroyed everything in his path. This is known as being very brutal because he mostly destroyed civilian property. The southerners reaction was shock, as they couldn't believe such brutal tactics were being used. Sherman's tactic was successful nonetheless. Challenges faced by freedmen were the inability to own land and lack of citizenship. The Freedman's Bureau was meant to help freed slaves get on their feet essentially.
As the Civil War drew to a close the primary issue on the mind of the North was how to reintegrate the South back into the Union. They settled on the famous 10% plan for this. Regarding the fate of the ex-slaves, the North instituted Reconstruction, which sought to make sure that the freed blacks would be integrated into Society fairly. This largely failed, however.
One of the different working conditions of slaves in the antebellum south was that these quarters consisted of a large grouping of rudely made cabins. Within these slave barracks, black families began to seize, hold, and extended families slowly gained approval for living together within the same homestead. This provided for the cultivation and flourishment of the black community. Southern slaves also tasted a small dose of freedom when allowed to plant and manage their own, small cash crops. This added to the home realm in which black life and expression overrode white intervention. The home began to represent more than just a form of shelter... it became the haven for the development of the African-American experience
Another one of the different working conditions of slaves in the Antebellum south was that many owners had experienced such runaway rates and unsettled behavior from their male slaves that they were forced to begin to buy more females, even though they were not considered as a valuable commodity. The main reason for the purchasing of slave woman had definitely been for reasons that involved the slaveholder's sexual desires rather than the female's economic potential. But slave masters soon began to buy an equal amount of black women and men for their plantations in order to ensure families and hence stable slave behavior. A married male slave had more responsibility to his mate and children and therefore would be more deterred from trying to escape.
Hope this helps
In the eighties, officials of the government of the President of the United States, Ronald Reagan, organized an operation to sell arms to Iran to finance the "Nicaraguan Contra", the right-wing guerrilla group that opposed the Sandinista National Liberation Front. , the party in power.
The sale of arms, moreover, was aimed at persuading Iran to release American hostages kidnapped by pro-Iranian groups in Lebanon.
The US Congress had prohibited government organizations from financing the activities of the Nicaraguan "contra". But officials of the Reagan administration, including Colonel North, appealed to the National Security Council (NSC), which was not explicitly mentioned in the law drafted by Congress, to raise funds for the guerrillas.
The members of the NSC also participated in the illegal shipment of arms to Iran. At that time there was a trade embargo imposed by the United States. The scandal was discovered in 1986 when Lebanese newspapers revealed the operation of arms sales.
