A few years ago, my dad gave me my grandfather's history textbook from when he was in high school in the 1930s in California. That was an interesting read. In addition to it having a slight racist bent when discussing non-European civilizations, it contained facts that are now considered to be nonsense. The further in the past it went, the more it contradicted what are now considered to be well-known facts about the past. It really demonstrated the many decades of changes in attitudes toward non-European people and all the incredible things that have been discovered since then through archeology, carbon-dating, and genetics. I thought it worth reading to give me an insight on how people thought back then and their view of the world.
