I want to know the answer to the following question:
What was the case of Everson v. Board of Education the first instance of?
All the background I'm provided with is that "This was the first case in which the court applied the Establishment Clause to the laws of a state, having interpreted the due process clause of the Fourteenth Amendment as applying the Bill of Rights to the states as well as the federal legislature.". Is that enough to answer the question?
