Around the Mediterranean, plenty. However those polities collapsed during the Bronze Age Collapse. Less so in more northern climes where the weather is harsher and where we don't have much in the way of records, though we do have evidence of highly-developed cultures such as evidenced by structures such as Newgrange in Ireland, and evidence of trade corridors from Britain and Ireland down though the straits of Gibraltar to those Mediterranean kingdoms.
