Final answer:
The conclusion of the Civil War in 1865 resulted in a territorially united nation, the beginning of a journey towards emancipation and bi-racial democracy, and significant human and economic costs as soldiers and civilians alike adjusted to post-war realities.
Step-by-step explanation:
When the guns of the Civil War fell silent in 1865, the tumultuous four-year conflict had produced several significant outcomes.
Firstly, the land was territorially united, and the concept of secession had been soundly defeated, as mentioned in the Gettysburg Address, ensuring that the nation would persist 'under God, with a new birth of freedom'.
Secondly, a new reckoning with the issue of emancipation was front and center, with African-American soldiers and civilians alike contributing to and reshaping the narrative around freedom and equality.
The national duty then became how to secure the freedom for the newly emancipated and to construct a bi-racial democracy.
Lastly, the end of the Civil War brought immense human and economic tolls, including over 800,000 military deaths, and innumerable others suffering from injuries and psychological trauma as they returned to their communities.
There were also challenges of transition for the South, given the massive shift in social and economic systems due to the end of slavery.
