The Moors introduced the dirty filthy European cacs to not shitting where you live and bathing.
The actual toilet was invented centuries later, but as far as digging holes and living in filth that was all cacs first.... hence all the fucking plagues they had, I believe it was the black plague that was damn near wiped out after those mfkrs started bathing and washing their hands....thanks to the Moors
