We still have monarchies, but many of them are also democratic (hereditary monarch plus elected prime minister and legislature). I agree we still have tyrannies too, because I think there's a cycle between them and democracies. Democracy weakens, a tyrant takes power, this lasts for a while before collapsing, then his competitors take power themselves (in some cases, democratically).
