The Mandate of Heaven (or Tian Ming) is a political doctrine that the Zhou Dinasty implemented to justify the rule of the Emperor of China. The main idea was that there should only be one ruler of the country and he was on charge with the approval of the gods as the "<em>Son of Heaven</em>". If the ruler was unfair or didn't serve his people well, he could lose the Blessing of the gods and was consider to be bound to be removed from power (The cases in which the King was overthrown, or the people suffered any kind of natural disaster or famine were considered signs that the gods have removed the Mandate of Heaven).
When the Treaty of Guadalupe Hidalgo was signed in 1848, the US contained fifteen free and fifteen slave states. Controversy surrounded all of the proposed solutions to the problem of slavery in the territories. Additionally, northerners railed against the legality of slavery in the District of Columbia, and southerners, in turn, complained of northern failure to comply with the Fugitive Slave Law. All of these issues had to be resolved if new states were to enter the Union.
