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:

Social consequences:

most people now work in jobs where they do one  kind  of work; they are carpenters, bankers, cooks, mechanics, and so forth. likewise, most  businesses produce  only certainkinds  of  goods  or  services, such as cars, tacos, or gardening  services. this feature of  production  is known as specialization.
