What is the theme in The Labyrinth of Solitude: Life and Thought in Mexico by Octavio Paz?

Violence is one of the issues that pervades the book. The beginning of Mexico marks conquest that violated the existing civilizations. It ended with Moctezuma's suicide. Conquest was shared by all missionaries and bureaucrats who engaged in personal battles. The extermination of Indians was only partial as Indians were needed for work on haciendas. Even though their beliefs were also violated, Indians persisted in maintaining their own religious backgrounds.
