Some conflicts are passed down from generation to generation, either because of their size, or because they simmer at a low boil with little violence. Others were ostensibly declared wars that never ended due to various diplomatic irregularities or political quirks. In either case, the wars listed here are the longest wars in history.
In fact, the longest war in history, the Punic Wars, lasted over two thousand years - but only had 80 years of combat. Another incredibly long war, the 335 Years War, never had a shot fired and had been forgotten about until a ceremonial treaty was signed ending it.
At the same time, some conflicts that have lasted for decades have seen incredible violence, massacres and bloodshed - often between countrymen. There's nothing fun about the longest war, and these wars all long wars all lasted longer than 30 years, either because they just dragged on for a long time or there was never an official peace treaty. Read on to learn more about the longest wars ever, some of which are still being fought today.
