According to Jewish, Christian and Islamic tradition, monotheism was the original religion of humanity; this original religion is sometimes referred to as "the Adamic religion", or, in the terms of Andrew Lang, the "Urreligion". Scholars of religion largely abandoned that view in the 19th century in favour of an evolutionary progression from animism via polytheism to monotheism, but by 1974 this theory was less widely held, and a modified view similar to Lang's became more prominent. Austrian anthropologist Wilhelm Schmidt had postulated an "Urmonotheismus", "original" or "primitive monotheism" in the 1910s. It was objected that Judaism, Christianity, and Islam had grown up in opposition to polytheism as had Greek philosophical monotheism. More recently, Karen Armstrong and other authors have returned to the idea of an evolutionary progression beginning with animism, which developed into polytheism, which developed into henotheism, which developed into monolatry, which developed into true monotheism.
