Concert of Europe
The 'Concert of Europe,' a period from after the Napoleonic Wars to the Crimean War, was an example of peaceful multipolarity (the great powers of Europe assembled regularly to discuss international and domestic issues). World War I, World War II, the Thirty Years War, the Warring States period, the Three Kingdoms period and the tripartite division between Song dynasty/Liao dynasty/Jin dynasty/Yuan dynasty are all examples of a wartime multipolarity.
