Answer:
Slavery
Explanation:The United States became a continental nation with the purchase of Louisiana from France in 1803 and the settlement of the lands beyond the Appalachian Mountains. Westward expansion fueled conflict with Native populations and led to their forced removal. By 1820, 2 million Americans lived west of the Appalachians, out of a total national population of 10 million. The regional cultures that had developed along the Atlantic Coast—New England, Middle Atlantic, Chesapeake, and Carolinas—were transplanted into the Old Northwest (Ohio, Indiana, Illinois, Michigan, and Wisconsin) and the Old Southwest (Arkansas, Kentucky, Louisiana, Missouri, Tennessee, and Texas). But although Americans had begun to identify themselves as a nation, they were divided by sectional interests that deepened with rapid industrialization and the question of slavery.
What war is this involving? If WW1,
Distinctive bright blue uniforms, though earlier in the war they carried dark blue uniforms with red trousers.
Here are why the other answers are incorrect:
A. No side really used camouflage on most soldiers. This was a practice that was started in (with the Germany) WW2, but eventually grew with the years to come. And for guerrilla warfare, the French didn’t use it. They used napoleonic tactics in the early stages of WW1.
C. I believe the most common style of close combat was the bayonet charge/usage, which was used by all sides.
D. Most sides were using older rifles, including the French, which were from the 1880s-early 1900s.
Hope this helps!
One result was that King George III would not let colonists settle west of the Appalachian Mountains.
