The created the stamp act that taxed colonist on all paper products that they used
The Quartering Act of 1765
Jim Crow Laws enforced segregation between black and white people. The court case "Plessy Vs Ferguson" was trying to please people by enforcing the "separate but equal" law. Basically, they wanted to make the two races separate, but they thought it would be fine as long as both places were the same in quality and quantity.
To sum it up, Jim Crow Laws were to separate the two, but black people were given schools that weren't as good, trashy bathrooms, etc. It was also made to make sure that black people could not go some places on certain days, or at all. The "Plessy vs Ferguson" case was to try to make it better by separating the races, but having both bathrooms the same and both schools the same so none is better than the other.
I hope I helped.
Actually why argue about the speed limit. It is there for everyone's protection. It is there for a good reason. So why argue about it? Yes some people don't follow it. But that is the job of a police officer not of some kids in 6th grade. My point is don't argue against it argue for it.
