democracy breaks down over time, are you familiar with how the Greeks view the cycle of government?
Democracies will fall apart because over time, the people will not pick the best leader but the person who promises them the most goodies, this leads to chaos and a single authortarian leader will raise up, a monarch, over time, the power of the monarch will be diffused and more and more people will get power, this leads to an oligarchy or ruleing class, then over time more and more people get to vote/rights/land whatever and it becomes a democracy.
It can go other ways too, democracies can turn into oligarchies or if there is a major breakdown in a monarchy (not the king and queen kind but the mono = one kind) it can go straight to democracy
