"Ancient Society: or, Researches in the Lines of Human Progress from Savagery, through Barbarism to Civilization" by Lewis H. Morgan, is a groundbreaking late 1800’s research publication, discussing how human societies evolved, arguing that all people moved from basic savagery, through different levels of barbarism, to reach complex civilization. Its goal involves displaying the consistent and unified advancement of humanity by examining the history of social organizations, creations, and establishments. It begins by introducing the idea that humanity started with primitive cultures and developed towards more advanced organizations, noting proof that savagery came before barbarism, and barbarism advanced into civilization. He presents his concept of separate ethnic periods, connecting the expansion of human society to advancements in technology and cultural habits like how people lived, ruled, and structured their families which acts as the basis for analyzing societal growth.
