Many American Genocide deniers argue that the only evidence on such facts is the Brief Destruction of the Indies, written by Father Bartolome de las Casas, but this scheme hides the same archaeological and documentary evidence (chronicles of conquest).This error produced by the same education or membership or denial of an American ancestry, genocide deniers rely on books or resources where archeology is absent, nothing is known before the European landing, except for small memories. There is a profound study of history American, which has been done many times bypassing the American groups and hiding genocide. Only known scholars, archaeologists and enthusiastic researchers are still many questions and enigmas. Bartolomé de Las Casas was not the only one who wrote about the American genocide, they did before the same genocidal Europeans of their own hand, several accounts of such atrocities are in different sections of this site. Here transcribe some passages summarized Chronicle Bartolomé de Las Casas: Come to the Island that the Europeans renamed The Spanish in 1502. Get a parcel and see the killing of origin . Due to the atrocities against the original inhabitants of the Caribbean (destroyed by the genocide of Europe), made several petitions of grievances. It proclaims that European settlers settle to populate the islands that were already depopulated by disease and massacre (first germ of the invasion, dependency and colonialism imposed by Europe). Las Casas get some land by Charles I, land captured from the Americans by physical invasion. In 1523 theMexica killed many Christians in the town of Cumana, Las Casas realizes that it is impossible to pacify the Aztecs because of the ambition and the ravages of genocide in Europe. At the time, Las Casas discussed in a world of mind slave, medieval , racist and intolerant (very similar to the present) "the rights of the Indians" (discussed even today after so many centuries, demonstrating the involution of human thought in every sense). It also discusses the right of the Catholic Monarchs to make war under the pretext of paganism. This ground is as old pillar of the legal justification for subsequent laws and social stigma suffered by all Americans, Native Americans and mestizos. The date of 1526 in which Bartholomew wrote the General History of the Indies, check the atrocities known that for decades and then centuries led Europeans. It was the first Human Rights Treaty protected the American man, long before the appearance of the concept of human rights as such. This letter considers the U.S. as a full human being, like any human being and the unjust war of the conquerors causes the righteous rebellion of the Americans. in Nicaragua denounced the sending of slaves Peru.Meet in Spain to Bartolmé de Carranza and Francisco de Victoria ,whosaid that the pope has no right over the world and can not grant the right of princes to evangelize. Las Casas repeats ad nauseam "not be given to the Spanish Indians in encomienda", this desire was much support from Carlos I, involving the Indian Council for corruption and slavery as strong evidence that everything he said was Las Casas a reality. In 1550 Charles I brought to debate whether the Conquest (germ of what would be the subsequent genocide) is lawful or not .As an advocate of genocide and the current natural condition of the American slave is Juan Gines de Sepulveda (which has streets in his honor in South American countries that have governments with genocidal minds). For this defender of slavery, Americans were barbarians (as the medieval concepts, which continue to apply for genocide and Europeanized minds even after independence from the Spanish crown, but inheriting all its institutions and leaders of European origin ). To The American Homes was a full human being. Thus the humanist thinking was centuries ahead about the birth of human rights in the nineteenth century. He was the first white spokesman defended the Human Rights of Americans, but made mistakes that could not see, such as evangelism even by peaceful means. There is no peaceful evangelization, all evangelization is a change in the value structure and spiritual human being.

Las Casas was the first European who spoke of killings of large groups of people and we know today as genocide, but using other terms involving the same idea is now defined as awful word: the killing of innocent people and destruction of villages and deserts. These words are also back in the chronicles of Cortés citing innocent people and a lot of fear (there were massacres of defenseless people throughout America, as in the conquest of what would become the territory of the United States). 
As I say in the Top of this page, crimes committed in those times if committed today would be properly called genocide or crimes against humanity (indeed the word we use does not detract from or add too much). What does matter is that we understand in depth what we know and know in the area or know and what we actually know a very small part. 
If in those days there were no laws to condemn these crimes, if there was much stronger moral principles that the laws themselves and Catholic religion with biblical commandments literally say what are the sins. All this world of principles, beliefs and social norms (the basis of subsequent laws) was broken in a systematic and ruthless by the conquerors. Many historians support the last conquest or genocide (seeing with the eyes of this just to give a modern classification), denying the systematic nature of the conquest, attributing to the ethnic genocide (mixing) a degree of unity between peoples, as an amalgam necessary and dear among them, some historians speak of the conquest of America as an act of love ... 

Las Casas says that the conquest is unjust, tyrannical and all natural and divine law, condemned, hated and cursed. Describe the greed and ambition of Europeans (the defenders of the conquest historians deny this, no evidence), in the chronicles of the conquest, written in the handwriting of the conquerors described fínismos objects of gold and silver, emeralds, stones precious, slaves, women in prostitution by force, and other spices that Europeans stole, and destroyed profited.
