Johann Jakob Bachofen (22 December 1815 – 25 November 1887) was a Swiss antiquarian, jurist, philologist, anthropologist, and professor for Roman law at the University of Basel from 1841 to 1845. Bachofen is most often connected with his theories surrounding prehistoric matriarchy, or Das Mutterrecht, the title of his seminal 1861 book Mother Right: an investigation of the religious and juridical character of matriarchy in the Ancient World. Bachofen assembled documentation demonstrating that motherhood is the source of human society, religion, morality, and decorum. He postulated an archaic "mother-right" within the context of a primeval Matriarchal religion or Urreligion.
