Judicial power

During the hundred years between the Civil War and the Civil Rights amendment many states, mostly in the south, relied on the tenth amendment to protect them from outsiders trying to change their society. This society wanted to maintain Blacks as second class citizens. The amendment says, The powers not delegated to the United States by the Constitution, nor prohibited by it to the States, are reserved to the States respectively, or to the people. This plan of action used by these states was referred to as States Rights. They didn't want the Feds coming into their states and telling them what to do. Slowly over time the states lost this battle because the Feds used the courts to force the states to change. It was mostly liberals who used these courts and to negate many laws that were deemed prejudicial. The new Supreme Court has reversed this trend and is sending power back to the states. This trend started under Obama and Trump and is amplified under Biden. The court has been routinely ruling against executive orders limiting the power of the president and moving things back to the states limiting the power of congress.
