Quick answers
Are the scores a ranking of nations or armies?
No. Scores are browsing aids inside an era-bounded atlas — not live league tables of countries.
How many died?
About 620,000 was the long-standard military estimate; recent work (Hacker and others) suggests around 750,000, with a published band reaching about 850,000 when some civilian deaths are considered. Disease killed more than combat.
Was it about slavery?
Yes, as the cause of secession. Lincoln's initial public aim was union; emancipation became a war aim in 1862-63. Both facts are true and in sequence.
Why did the Union win?
Population, industry, rail, naval blockade, Black manpower, and -- in 1864-65 -- a coordinated strategy under Grant. Confederate advantages in interior lines and military culture were real and insufficient.
What was Gettysburg?
A three-day battle in Pennsylvania (1-3 July 1863) that ended Lee's second northern invasion. Combined with Vicksburg's fall on 4 July, it was the war's political-military hinge -- not the last fighting.
What did Reconstruction do?
It briefly empowered Black voters and Republican governments in the South, passed the 14th and 15th Amendments, and then collapsed under violence and northern fatigue after 1877.
The 14th Amendment's birthright and equal-protection clauses still structure US litigation -- a live legal legacy.
The US Army's professional self-image runs through Grant and Sherman more than through the Indian Wars it also fought.
Lessons
Industry plus politics
Factories without emancipation diplomacy might still have been a longer war.
Victory can be reversed socially
Amendments without enforcement became paper.
Civil wars make memory wars
Statues are arguments in stone.
Disease is a belligerent
Camps killed more than famous charges.
Unresolved
Exact death toll
Still a scholarly range.
Monument landscape
A live municipal and state fight.
School standards
Slavery's centrality is still contested in some US legislatures.
Repair politics
Reparations debates cite this war's unfinished economic ledger.
Shifts
Second founding
13th-15th Amendments as a new constitutional baseline.
Federal power
A war presidency and a larger peacetime state.
Abolition of property in people
The central economic revolution -- without forty acres.
Modern US military seed
A mass-war experience the later world wars would dwarf in the world, not in US deaths.
Outlook
Public history in flux
NPS labels and museum rewrites are the current campaign.
Data revisions
Digitised census work still moves the death band.
A domestic argument
Unlike 1918, this war's meaning is still a US election issue.
Risk
memory conflict
The armies surrendered. The live risk is civic: a civil war taught as romance or as denial can still poison a republic's self-account.
Jim Crow was a counter-revolution. The civil-rights era was a second Reconstruction -- the comparison is standard among historians.
Foreign readers should not mistake battlefield tourism for a settled national story.
