Did the Ottoman Empire wipe all of them out, or what? I know that many people in Greece are Turkish and have become Turkish. But doesn't that mean Greece should be Turkish too??? Aren't Greeks technically Turkish????
As you are waiting you might read some earlier answers. In this thread u/xeimevta writes a great answer about what happened to the Byzantine nobility. You can read more about Byzantine-Ottoman continuity in administration here by u/Sinan-Pasha96 and here by u/Ornlu-wolfjarl, as well as here where u/amp1212 has a different perspective and is questioned a bit by some of our flaired users. There have also been discussions on Greek experience and Greek identity after the conquest, like in this answer by u/ByzantineBasileus, this one by u/Anthemius_Augustus and this by u/Chamboz
