That’s the subject of my latest at RealClearHistory (I submitted it before the vicious, anti-Muslim shooting in New Zealand occurred). An excerpt:
7. Chios massacre (March – July 1822). The Ottomans were bad people for a few centuries during the Middle Ages (RealClearHistory has more on the Ottomans here). In 1822, Istanbul massacred 52,000 Greeks on the island of Chios during the Greek War of Independence. The massacre was used deftly by imperial proponents in London, Paris, and Moscow, and further isolated the Ottomans from European diplomacy. As for the inhabitants of Chios, most were apathetic toward the rebellion until the massacre.
Here’s another one:
5. Massacre of the Latins (1182). In the 12th century, Roman Catholics in Constantinople, the capital city of the Roman Empire, were known as Latins and in 1182 they were slaughtered, driven out of the city, or sold into slavery. Tens of thousands of people are estimated to have died. The massacre occurred because the vast majority of non-Roman Catholic inhabitants were much poorer than the Latins of the city, due to the latter’s connections to the wealthy city-states on the Italian peninsula (Venice, Genoa, Pisa, etc.). The massacre also made it harder for the Pope to unify the Christian world, as the split between Catholic and Orthodox sects only became more hardened.
Lots of bad things have happened in Turkey and Greece and over the years. Please, read the rest. There’s more massacres, but also thoughts on the genocide-versus-massacre debate, and the sheer lack of knowledge that humanity possesses in regards to its own history.
