When we consider democracy as being a process of government rather than a "type" of government, we can begin to identify what what we would call democratic values and mechanisms in other societies. However, it is important to note that our current vision of these concepts usually do not translate 100% into the structure of the past.
Ideas of democracy are commonly attributed to the Western World, but their envisioning and development did not occur their in isolation. Several hundred years before the colonization of the Americas, for example, the Haudenosaunee implemented what we now refer to as "The Great Law of Peace." Acting as essentially their constitution, this framework for democracy among their societies has even arguably had a substantial influence on the forming of the United States Constitution.
I've written several answers in the past regarding this, to which you can find here:
