A: The Civil War
Assuming that you're talking about the American (U.S) civil war, that is.
The civil war was a conflict between the rights of the (slave owning) states and the national government. A war about state rights.
The war of 1812 was between 2 independent, sovereign nations.
The great depression was just an economic thing.
The northwest ordnance, I have the least knowledge of, but it still wasn't between states and the national government.
Hope this helps.
The action that Japan took in an attempt to recover from the Great Depression is that D. Japan seized control or resources in other nations.
That way, Japan had a lot of resources to fight the consequences of the Great Depression which left the country struggling.
Creation of the League of Nations, and hurt land across Europe (no man’s land)
Law of the Twelve Tables
Rome's laws that were written on 12 bronze tablets! Written down to protect people's rights so that everyone knew what the laws were.
"The best known ancient code is the Babylonian Code of Hammurabi. The Romans began keeping legal records, such as the Law of the Twelve Tables (451–450 bc), but there was no major codification of Roman law until the Code of Justinian (ad 529–565), which was compiled long after the dissolution of the Western Empire."
