Religious pluralism is part of more general pluralism and tolerance. Where one occurs so it is likely that other forms of tolerance will also occur with the most religiously tolerant states being pluralistic democracies. The reason democratic peace has gained in popularity is the difficulty of finding conflicts where two democracies have fought each other. This is less difficult when considering two religiously tolerant societies. One difficulty would be working out when a society is tolerant when the UK and Argentina fought over the Falklands Argentina was certainly not a democracy but was it particularly intolerant? [1]  It is notable that Europe’s most tolerant period of history prior to the second half of the 20th century was the late 18th century when the enlightenment spread religious tolerance as far as Russia [2] but the French Revolution’s declaration “No one should be disturbed for his opinions, even in religion, provided that their manifestation does not trouble public order as established by law” certainly did not usher in an era of peace. [3]  Finally while the spread of democracy can explain the increase in interstate peace in the modern era it does not have a long history through which it can fall down. However religious tolerance has often been a norm before the idea of an exclusive god came along; Buddhism merged with Shinto and Daoism in Japan and China, the Roman empire regularly added gods from its conquests, and some of the world’s greatest conquerors such as Akbar in India have been open to all religions.
