How were the Albanians treated in the Ottoman Empire? Did they adopt Islam to appease to the Turks or were they significantly Turkified at some point?
Albanians and Bosnian Serbs were either allies, auxiliaries, vassals or enfranchised nobles of the Turks even since Pecheneg Turks way back in 11th century.
Most Turkified Albanians and Bosniaks are basically close special relationships during Pecheneg, Seljuk, Ottoman times nearly for a millennium. Those serbs who fought beside Beyazid the Thunderbolt against Timur's Army in the Battle of Angora were given "timarli" status (only given to Turkic landowners) as a sign of their bravery. Most (including members of Stefan Lazarevic's family) accepted the honor and had holding inside the Empire. Gradually they willingly converted.
It must be remembered that Albanians and Bosniaks had special status in Ottomans as "blessed of the new" faithful. They willingly converted, were fully integrated into the state, nobility and army.
Balkan Muslims were generally respected and often given very prestigious positions.
Abanians were pretty Islamic until the advent of Hoxha's meme communism.
I wonder if Albanians realize how stupid they sound when they say " I'm not Muslim/Christian... my religion is Albanianism" For some reason keep hearing it from them.
