Tom --

Reconstruction ended when the last of the Federal troops stationed in Southern states were withdrawn. Reconstruction by Congress reflected the will of the people in the Northern states. If a Northern congressman lost his seat, it was usually because he was 'soft' on Confederates and post-war policies towards them. Andrew Johnson was impeached for that reason.

The comment that Southerners prevailed against the government in Washington after war is commonly heard. What does that mean?
What, for instance, might the Federal government have done differently in Arkansas?

I don't understand how the placement of courthouse monuments a century or so ago "proves" anything about Reconstruction, which ended in 1876/77. Can you explain?
