A democracy government dramatically increases trade in the same manner as a republic and has one major additional advantage. There is no corruption in cities under a democracy, which makes it very useful for large empires. However, a democracy has two unique worries. First, military units not in their home city cause two citizens to be unhappy, not one citizen as in a republic. This makes war especially hard to wage. Also, if any city in a democracy slips into civil disorder, the government is immediately overthrown and becomes an anarchy for several turns. While a democracy has tremendous economic advantages, it is fragile and requires vigilance.
