The United States had to face several challenges in redefining the union after the war. Two main problems were: how to deal with the Southern states that were still angry for losing, and what they should do with the ex-slaves. It was difficult to get American together after many people died in the Civil war and big part of the South was destroyed by the battles.
Apart from that, they had other challenges such as: building a solid economy, creating a stable political system, preserving the national independence (reducing conflicts with other nations and the nation itself), fostering American shipping, consolidating public support, reducing debts, etc.
During WW1 (and WW2 to a degree), most young men were often drafted into the military to fight, while most young women worked in factories to produce materiel for the war effort.
The developments made in the Compromise of 1850 was the Fugitive-Slave law and the ban on the slave trade in the nation's capital. The Fugitive-Slave law was declared for runaway and captured slaves to be returned to their respective owners.
Answer:
I'm just going in order
1. separation of powers
2. federalism
3. checks and balances
Explanation:
Separation of powers is when power is divided into branches. For example, the US having three branches of federal government.
Federalism is when the federal government has some power, but subnational units also have some power. For example, the US has a federal government in Washington, DC, state governments such as the state of Florida, and local governments such as the city of Miami.
Finally, checks and balances are when the branches of government can "check" one another. For example, a president vetoing a bill from Congress would be a "check" from the executive branch to the legislative branch. This way, every branch has roughly equal power.
Hope this helps!
