I read on https://www.thevintagenews.com/2018/01/16/ramesses-ii-passport/ (mirror):
However, in order for Ramesses’ mummy to be transported to France, the long-deceased pharaoh needed to have a valid passport. At that time, French laws dictated that all persons, dead or alive, needed to have valid identification documents in order to legally enter France.
Do deceased persons still need to have valid identification documents in order to legally enter France?
