Something being normal is simply widely practised or widely encoded into law. It doesn't make it right or without struggle nor does it take away from the conflict. It was part of the reason there was conflict and struggle. Knowing what was normal - widespread, encoded in law, and other such things - is part of understanding what the struggle was all about. Normal doesn't equal correctness, just what was average and widespread at the time.
