What does Gary Gallagher say caused the American Civil War? Show answer

Slavery. He says every condition for war was tied to it, and that the argument before the war was about whether slavery could expand into federal territories.

A tiny minority, about 3% of white Americans by his guess, and much despised even in the North as agitators.

Why did most white Union soldiers fight, in Gallagher's account? Show answer

For the Union. They saw the republic as a gift from the founding generation, which later made it easier to remember the war without slavery at its center.

What did the defeated white South settle for after the war? Show answer

Having lost a slave-holding republic, it scaled back to keeping white supremacy, which produced Jim Crow.

Why did Reconstruction fail to secure Black equality, yet still matter? Show answer

There were at most about 30,000 troops in the South and white Northerners would not enforce equality. But the 13th, 14th and 15th Amendments stayed on the books for later use.

What is the Lost Cause? Show answer

The Confederate memory of the war, which claimed it was not about slavery, that the South could never have won, and that it fought for constitutional principle.

More than 40,000 slave ship voyages over three and a half centuries, carrying about 12.5 to 13 million Africans.

What happened on the slave ship Zorg? Show answer

After navigation errors left it short of water, the crew threw 130 to 140 Africans overboard, and the owner filed an insurance claim. Exposure of the case started the first abolition movement.

What was the catch in Britain's 1833 abolition of slavery? Show answer

The government paid slave owners £20 million, not the enslaved, and the enslaved had to serve five more years of unpaid apprenticeship.

What is Kara's position on reparations? Show answer

He holds that a debt exists in principle but has no firm view on how to pay it, since it is unclear who would receive the money and how it would be distributed.

How does Josh Dubin connect slavery's legacy to today's justice system? Show answer

He points to a book on caste for how redlining and Jim Crow still shape communities, and argues that circumstance and unaccountable prosecutors decide who ends up in prison.

What limits does the article place on linking slavery to modern policing and courts? Show answer

Not every court failure traces to slavery, the sources give no data on race in police encounters, and they never say the Ohio case was driven by race.
