Study Tips for Civil War & Reconstruction

1

Treat the sectional crisis as a chain: Missouri Compromise → Compromise of 1850 → Kansas-Nebraska Act → Dred Scott → election of 1860. Each event made the next more likely. Sequence cards lock in this causation.

2

Build a single comparison card for the three Reconstruction plans (Lincoln, Johnson, Radical) with one row per plan and columns for leniency, civil rights, and political restrictions.

3

Memorize the Reconstruction Amendments by their three-word summary: 13th = abolish slavery; 14th = equal protection; 15th = voting rights. Then add the year and a one-line caveat (Black Codes evaded the 13th, etc.).

4

For each major Civil War battle, learn the date, location, victor, and one sentence on its significance. Antietam, Gettysburg, Vicksburg, and Sherman's March are the highest-yield.
