There are no known societies that are unambiguously matriarchal
Matriarchy - Wikipedia, the free encyclopedia : "There are no known societies that are unambiguously matriarchal,[1][2][3][4][5][6] although there are attested matrilinear, matrilocal, and avunculocal societies, especially among indigenous peoples of Asia and Africa,[7] ... In 19th century Western scholarship, the hypothesis of matriarchy representing an early stage of human development—now mostly lost in prehistory, with the exception of some 'primitive' societies—enjoyed popularity. The hypothesis survived into the 20th century and was notably advanced in the context of feminism and especially second wave feminism, but this hypothesis of matriarchy as having been an early stage of human development is mostly discredited today, most experts saying that it never existed.[10]"
