Ear piercing and nose piercing have been particularly widespread and are well represented in historical records and among grave goods. The oldest mummified remains ever discovered had earrings, attesting to the existence of the practice more than 5,000 years ago. Nose piercing is documented as far back as 1500 BCE. Piercings of these types have been documented globally, while lip and tongue piercings were historically found in Africa cultures and so many more but is actually from the Middle East. Nipple and genital piercing have also been practiced by various cultures, with nipple piercing dating back at least to Ancient Rome while genital piercing is described in Ancient India c. 320 to 550 CE. The history of navel piercing is less clear. The practice of body piercing has waxed and waned in Western culture, but it has experienced an increase of popularity since World War II, with sites other than the ears gaining subcultural popularity in the 1970s and spreading to mainstream in the 1990s.
