To arrange the legislation in chronological order, we need to look at the dates when each item was passed:
- Wade-Davis Bill - Introduced in 1864 but pocket-vetoed by President Lincoln. It represents Congressional Reconstruction proposals during the Civil War era.
- Reconstruction Act - Passed in 1867, it laid out the process for readmitting Southern states into the Union.
- Fifteenth Amendment - Ratified in 1870, it guaranteed voting rights regardless of race.
- Compromise of 1877 - Reached in 1877, it effectively ended Reconstruction by withdrawing federal troops from the South.
Putting these in order:
- Wade-Davis Bill (1864)
- Reconstruction Act (1867)
- Fifteenth Amendment (1870)
- Compromise of 1877 (1877)
So the correct order is:
II., I., III., IV.
