In history, one can view applied ethics through the decisions of governments as they were influenced due to the religious mores of their time. On a more general level, which deals with history—the Ottoman Empire, which used to span the globe—effected the territories it owned with its prevailing religion. Constantinople, at the end of his life, professed the Christian faith. However, the name of the city Constantinople was later changed to Istanbul after the geopolitically-defined, mainly Muslim, country of Turkey came into prominence. Applied ethics can be seen all over the world, not to mention a lack of application of ethics in world history. For example, when Hernan Cortes and his men came to Mexico, the land of the Aztecs—to hoard gold and other valuables—the Aztecs thought this was fulfilling a prophecy that their great leader would come from far away. Instead of admitting that Cortes was not the leader he was who they thought, Cortes took advantage of the fact that the Aztecs thought he was a holy figure, and consequentially took the wealth of the Aztecs, his men raping their women and killing a lot of people, including roasting the Aztec leader Cuauhtemoc over a fire pit and pouring boiling oil over his feet. The point is, types of domination like this went on all over the world. Christopher Columbus never indeed “found” the New World, but he found plenty of island natives in the Caribbean whose peaceful lives he ruined by the ruthless plundering of himself and his men. There is evidence of all of these types of cruel inhumanity present in all of history—and it is not just limited to the Europeans, although they were a major cause for discontent the world over. If one thinks about it, in world history—the British Empire once spanned a majority of the globe. The French and the Dutch also had colonialized several countries in Africa, Asia, and the Americas. Due to these white peoples taking over indigenous nations’ peoples and forcing their values, religion, language, and culture upon them—they were forced to either change or die. So, these people adapted. More about evolution and ethics will also be discussed in the last section of this piece.
Morality became politically-correct (or ‘PC') after the civil rights movement in the ‘60s in the United States, because it meant that any kind of oppressed people (not just Blacks) could basically rise up and say that they weren't going to take being discriminated against anymore. Of course, this has led to postmodernist thinking, that everyone is equal and everyone's perspective has to be right because no one is wrong; we all worship the same God even though some of us may not call God God, nor does everyone
