Two links on an interesting topic:
1) When Turkish was written in the Greek, Armenian and even Syrian script, by Michael Erdman:
The two largest allographic communities were the Armenians and the Greeks. Armeno-Turkish – a rendering of Ottoman Turkish in Armenian letters – gave rise to a vibrant publishing industry and cultural community. The orthography was largely phonetic and based upon Western Armenian readings of the letters. It was in Armeno-Turkish that many French and other Western European works came into Turkish. This was a situation assisted by the reticence of the Sublime Porte to authorise Ottoman Turkish printing presses, despite the expansion of Armenian, Greek and Jewish ones. […]
Turkish written in Greek characters also laid the foundation for a vibrant publishing industry, with a heavy emphasis on religious materials. The language, known as Karamanlidika in Greek and Karamanlıca in Turkish, was the everyday idiom of the Turkish-speaking Greek Orthodox Christians of Anatolia. Despite being ethnically and linguistically Turkish, their religion required them to be classified as Rum or Greek Orthodox under the Ottoman system.
Lots of great illustrations; thanks, Trevor!
2) You should learn Ottoman Turkish, by David Selim Sayers:
If you reduced the Ottomans to Islam or Turkishness, they themselves would be the first to object. They rarely even used the word “Turk” without adding an insulting adjective like “idiotic,” “misshapen,” or “mad”. An Ottoman Empire consisting only of Turkishness would be just that: idiotic, misshapen, and mad.
You should learn Ottoman Turkish. However, that isn’t enough. Once you know the language, you have to forget everything you’ve learned about the Ottoman Empire, stand up for those rotting and looted archives you’ve never seen, dig into them, and rewrite Ottoman history. You have to read everything —from the poems Mehmed the Conqueror wrote for young boys to the correspondences of the Young Turks regarding the Armenians— and you have to share what you read with everyone. You cannot entrust this task to anyone else. Because entrusting history to others means allowing others to dictate your identity, attitudes, and life.
