《古代社会》一书,是摩尔根的第三部巨著,是他在原始历史观上达到的最高成就。摩尔根于1851年发表了他的第一部著作《易洛魁联盟》。这是美国出版的关于美洲印第安部落的第一部民族学专著。这一年,在美国,被认为是美国民族学诞生的一年。摩尔根在这部著作中,详细地记述了经过他认真研究过的易洛魁部落联盟的内部结构。书中所引用的材料,至今还没有失去它的学术价值。 The book “Ancient Society” is the third masterpiece of Morgan and is the highest accomplishment he has attained in the original view of history. In 1851, Morgan published his first book, the Iroquois Alliance. This is the first monograph published by the United States on the Native American Indian tribes. This year, in the United States, is considered a year of American ethnography. In his book, Morgan describes in detail the internal structure of the Iroquois tribal coalition, which he has carefully studied. The materials quoted in the book have so far not lost its academic value.
