Pl me quickly just a short response how did the civil war and reconstruction change the united states politically, socially, and economically? some historians have called reconstruction a “glorious failure”. how accurate is this description?

Hope this helps

Politically: Lincoln tried preserving the Union, so the South decided to secede and this led to war.

•The most unfortunate political consequence of the Civil War was Abraham Lincoln's death.

- Lincoln also issued the Emancipation Proclamation. It went into effect on January 1, 1863, and declared, "that all persons held as slaves" in states that rebelled "are, and henceforward shall be free." the proclamation changed the focus of the war

Economic consequences:

, the Southern economy was in ruins. Much of the war had been fought in the Southforeign nations that once bought Southern cotton began to produce their own. As a result, post-war cotton prices plunged dramaticallyJust like in the South, a large percentage of Union soldiers went home with injuries that prevented them from workingBuildings, railroad lines, and family farms destroyed in the war needed to be rebuilt. The nation as a whole needed to be reconstructed

Social consequences:

The Civil War allowed African Americans to make progress in society.  Following the Emancipation Proclamation, many free African Americans joined the Union armyThe population was reduced as a result of war casualties. Farms and homes had been destroyed.

The answer should be b.
