The Code of Hammurabi is a well-preserved Babylonian code of law of ancient Mesopotamia, dating back to about 1754 BC (Middle Chronology). It is one of the oldest deciphered writings of significant length in the world. The sixth Babylonian king, Hammurabi, enacted the code, and partial copies exist on a 2.25 metre (7.5 ft) stone stele and consists of 282 laws, with scaled punishments, adjusting "an eye for an eye, a tooth for a tooth" (lex talionis)[1] as graded depending on social status, of slave versus free man or woman.[2]
The Encomienda system left a lasting impact on the newly independent Latin American nations. Much of the local belief system and structure was destroyed and replaced with Catholicism. Many of the natives had been treated so poorly, abused, and taken advantage of that repairing the broken relationships was near impossible. The natives were extremely fearful of the Spanish and those that replaced them in power. They had been seen as less than human and simply a work force to use until they died, much as some slaves were seen in America decades later. Natives would face severe discrimination for years after.
