Spain
has a long history, and most of the territories have been named the
same for millennia, adapting to new languages and cultures. Some meaning
of these names are yet unknown, although there are interesting
hypothesis. These names come from Iberians, Celts, Phoenicians, Punics,
Romans, Greeks, Basques, Muslims, Visigoths, and Christians, among
others, which makes this country one of the most interesting in this
matter.
