All the bullet points listed above address American Civil War topics. I will relate the key words on each number that belong together, and then elaborate each one on the explanation section. (The question is incomplete: a bullet point is missing)
1 - The Wade-Davis Bill -----> required electorate to take an oath before readmission as a state
2 - Oliver O. Howard -----> chief of Freedman's Bureau
3 - Writ of Habeas Corpus -----> suspended by Lincoln
4 - Freedman's Bureau -----> helped blacks adjust to freedom
5 - John Wilkes Booth ----> assassinated President Lincoln
6 - Ford's Theatre ----> site of Lincoln's assassination
Step-by-step explanation:
1 - The Wade-Davis Bill that Senator Benjamin F. Wade and Representative Henry Winter Davis proposed required that 50% of a state’s white males took a loyalty oath in order to be readmitted to the Union. Furthermore, states were required to give blacks the right to vote as free men.
2 - Oliver O. Howard was a Union General during the US Civil War. He was given charge of the Freedmen's Bureau in 1865, with the aim to integrate the freedman into southern society and politics during the Reconstruction. He was given a Medal of Honor after losing his right arm in battle against Confederate forces in 1862.
3 - Lincoln suspended the writs of habeas corpus in 1863 to maintain order and public safety in a divided-by-war country, to try large numbers of civilian rioters in military courts and to prevent the Confederate troops to march on Washington. As senator Henry Wilson said in Congress, the aim was to «suppress insurrection and rebellion».
4 - Freedman's Bureau was an agency from the United States Department of War created in 1865, which helped newly freed slaves to obtain clothing, food, healthcare, education and jobs.
5 - John Wilkes Booth was a well-known American actor before he murdered President Lincoln in 1865. As a frustrated Confederate, he assassinated the President with the hope that it would change the Civil War outcome. He managed to escape the crime scene, but was later encountered by soldiers and shot in the farm he was hiding.
6 - President Lincoln was shot in the head by J.W. Booth while attending a play at Ford's Theatre in Washington. Lincoln had a place on Ford's family box, everyone knew he was attending to the play. Apparently, his personal security left the box, so Booth had no problem approaching him. Besides it is said that access was always easily granted because of his celebrity status.
