The Americas and Europe both benefited from the Columbian Exchange by new crops and new animals, but the Americas were negatively affected with new diseases as well as enslavement of the Native Americans.
The president is the supreme chief when it comes to the military and what the president decides the military has to do. Of course, they have numerous advisers who help them so it's not like they go and plan worldwide missions as they see fit. The president also negotiates treaties with other countries and represents the country in any affairs with foreign countries, both enemies and allies.
The congress has to ratify these treaties or give their approval for leading a war. This is to prevent the president from doing whatever they want to do and from being tyrannical and leading to pointless wars or getting treaties that don't benefit the American people. However, due to certain loopholes and various acts, there have been historical wars that presidents organized without the support of the congress.
The division of power should be considered reasonable because nobody can decide things on their own.
The Confederacy wins the battle, but they lose Stonewall Jackson by friendly fire. Why is Gettysburg considered a turning point of the war? What did the Union accomplish by capturing Vicksburg and Port Hudson? These two cities were on the Mississippi River.
The Greeks had a polytheistic religion. They had these stranger gods that were created to explain supernatural events. Things like the god of war, nature, sea, or fire. They had religious offerings toward the gods. The people built colosseums and altars just for the individual gods. They also believed the gods punished them for so and so. The Romans adapted similar gods and almost had the same religion as Greeks.
I think it is the atomic age. I hope this helps! :D
