That's a lot of questions! You need not give me the "brainliest," as I may only respond to a couple of those points for the sake of time here.
#2 in your list: In Lincoln's first inaugural address, he said: "Plainly, the central idea of secession is the essence of anarchy." In other words, if states could choose to secede from the union, then there was really no union and no government. (Anarchy is the absence of government.) Only if we abide by the constitutional checks we place on ourselves in a democratic republic are we exercising genuine government. Otherwise, we fall into chaos or some sort of dictatorial state. Lincoln felt that the whole concept of self-government was at stake, threatened by the South's desire to secede. Lincoln had to treat the secession of several states as an act of rebellion.
#5 in your list (closely related to #2): The states that had seceded already had caused the civil war, in Lincoln's estimation. The northern states had to respond to hold the union together. The southern states claimed to be afraid for their property, peace and safety with an administration like Lincoln's in charge. But Lincoln saw those fears as unfounded, that all states would continue to enjoy their constitutional privileges. But seceding from the union cut them off from all stability and security.
All human civilization is originated from the African Region and started to migrate to Asia, then to America and Europe
The daily life in the early civilization is actually really similar. And started to differ when they entered the Agricultural period because of the food resource that available near that region (Americans use wheat, Asians used grains, and the Africans used corns)
When it returned it to royal control, it was established as a state that had a local assembly which was some type of an early government that was supposed to be more democratic. Eventually it all changed due to historical things in America that we know of.

The answer I believe is Korean War
The correct answer is Formation of the British East India Company, the Sepoy rebellion, complete British colonization of India, formation of the Indian National Congress
The British east India company was a trading company that managed to colonize India through trade domination. When the Sepoy rebellion arose because of that, Britain resolved that issue and introduced the British Raj which meant that it was under British rule now, not under the rule of the company. This resulted in the creation of the National Congress which was the first nationalist party that fought for Indian independence.
