What are historical examples (pro and con) for direct democracy?

In a discussion on gerrymandering, I saw someone argue for direct democracy as an alternative and someone else argue that it inevitably leads to "Tyranny of the majority". They linked to this Wikipedia article.

To me, when I read that article, I see a lot of people concerned of what might happen, but very little of it actually happening. I googled "examples of tyranny of the majority" and most of the examples were cases of mobs doing things that would be considered crimes, which are not related to voting.

Are there historical examples of times people were given a more direct role in the government, and it turned wrong? Or historical examples of it going well?
