In 1776 Switzerland was not even called Switzerland, it was The Old Swiss Confederacy, and not even a single unified country. They didn't abandon the sovereignty of the individual cantons until 1848 when they adopted their constitution. I wouldn't call the canton situation a modern democracy.

I'll give you The Six Nations.

I don't know enough about the others to say specifically, but I suspect that much like Switzerland, they didn't reform their governments from a fuedal state to a modern state until the mid to late 1800s much like the rest of Europe.
