A timeline is a chronological presentation of events that are often used in history classes because they allow a better understanding of changes over time, especially for social movements, like Anita is trying to do.
Furthermore, although they used to require static images on paper, today they can be digital and even interactive, with the kind of visuals Aninta is looking for.
As there is only three main time periods, a timeline would not make much sense (I'm saying this because of the other answer). Therefore, a process diagram would be used in this situation, because process diagrams give, as the question states, "big picture information" about a certain topic. Process diagrams are also in chronological order, which is what the question is asking about. Hope this helped!
The people didn't like the Articles of Confederation because it was too weak. While the monarchy the people had been under was too controlling, the Articles of Confederation was too much on the other side of it, being too lenient and barely having the power to do anything.
They saw the laws as unlawful according to the 14th amendment. The blacks needed equal rights with the whites. You might want to double check the amendment number but im pretty sure its the 14th.
