Classic democracy doesn’t include human rights. If you’re not a male citizen you have no right to be heard, and even then, the majority have the right to execute or exile you if they find you annoying.

Modern democracy is build on a core belief that everyone is created equal and that we are each responsible for our own lives. Something which extremely similar to the core thesis of Lutherism which laid the foundation for the renaissance and the Age of Enlightenment that eventually led to modern liberal democracy.

It’s a lot more complicated than that of course, but this is the Internet not a PhD. :)
