Question: was the principle of self determination applied to areas outside of europe

Answer: Yes, The revolt of New World British colonists in North America, during the mid-1770s, has been seen as the first assertion of the right of national and democratic self-determination, because of the explicit invocation of natural law, the natural rights of man, as well as the consent of, and sovereignty by, the people governed; these ideas were inspired particularly by John Locke's enlightened writings of the previous century. Thomas Jefferson further promoted the notion that the will of the people was supreme, especially through authorship of the United States Declaration of Independence which inspired Europeans throughout the 19th century. The French Revolution was motivated similarly and legitimatized the ideas of self-determination on that Old World continent.
