"This is an incomplete list of those conflicts referred to as wars between democracies; many of the references are to the opponents and supporters of the democratic peace theory or liberal peace, which asserts that democracies never or rarely go to war with each other. Definitions of democracy and war vary; two supporters of the theory hold, on different grounds, that there are no exceptions whatever; others hold that it is a strong correlation, and therefore find marginal exceptions to be unsurprising, and in some cases illuminating.

[citation needed] Few students of the democratic peace discuss wars prior to the nineteenth century; democracies were extremely sparse - and whether Athens or Florence is comparable to modern democracies is debateable. Data sets on wars do not always extend back any further; data on much earlier wars - including such questions as the number of troops on each side - are difficult to obtain.[citation needed]"@en .
