"The History of the Islands (Volume 5 of 5)" was written by the eminent historian and missionary Bartolomeo de Las Casas. In his masterpiece, the author talks about the analysis of the history of the conquistadors and the colonization of Latin America. The book reveals the tragic consequences of the conquest and exploitation of Indian peoples who suffered from European expansion. This work is an important source for studying the history of primary sources and reflecting the dramatic events of the Indian East. "History of the Islands" is not only a historical narrative, but also a stone in the confession of centuries of silence and the memory of those whose lives were destroyed by relentless violence and the Inquisition.
