I want to know the answer to the following question:
Until what year did the Ottomans retain a band of territory including Albania, Macedonia and Thrace?
All the background I'm provided with is that "Up until 1912 the Ottomans retained a band of territory including Albania, Macedonia and Thrace, which were lost in the two Balkan Wars of 1912–13.". Is that enough to answer the question?
Answer: yes
