If you didn't or don't vote your fine, it isn't required by law for people to vote but it is pushed so then you know that you have a say in your countries ruling(This is only for the USA i don't really know other countries laws)
C because the US wanted to own everything (I passed advanced US History with straight A's bruh)
The Dred Scott Supreme Court case ruled that slaves are property and are allowed in all states/territories, even if slavery is outlawed in the state constitution.
This idea supports the concept of nullification, as states that abolished slavery would nullify (refuse) to follow this ruling because they felt it was unconstitutional.
This idea also limited the power of the federal government to restrict the expansion of slavery because the court ruled that slaves do not have legal rights and are considered property no matter where they go. This meant that slavery can essentially exist anywhere in the US and the federal government couldn't change that unless they made a national law/amendment that outlawed slavery.
For Germany? It would have been 'Sieg Heil'. Hail Victory in English. However there were many different fascist nations, so please specify.
