The Haudenosaunee Confederacy was a confederacy made up of five and later six nations. The nations agreed to abide by the Great Law of Peace, an oral constitution which promoted peace among the once warring nations. The Great Law of Peace included principles such as the division of power amongst the different branches of government, equal participation of citizens and the establishment of individual rights and freedoms. In the confederation, each nation had its own council with chiefs, which were chosen by the clan mother to deal with internal issues in each nation. There was also a Grand Council which dealt with issues affecting the six nations as a whole. The Haudenosaunee Confederacy is regarded as the one of the first and longest lasting participatory democracies in the world.
The Haudenosaunee Confederacy clearly demonstrates the importance of equality amongst individuals in a society, including between men and women, which is a major component of classical liberalism. This idea was extremely rare for the time period, and still is in some societies. The confederacy extended great individual rights and freedoms to those of the six nations, allowing them all to have the right to a voice in their government, as well as freedom of speech and religion. The ideas in The Great Law of Peace deeply impacted the ideologies of other societies, including the American Declaration of Independence, and therefore helped to spread the ideas of classical liberalism.
The Haudenosaunee Confederacy, which was founded upon The Great Law of Peace is also an example of a society protecting the collective interest of the group as a whole, as the unity of the six nations allowed for greater security. Therefore, one could argue that the Haudenosaunee Confederacy also spread the ideals of modern liberalism.
