I want to know the answer to the following question:
What principality did the Zakarid family form?
All the background I'm provided with is that "The noble family of Orbelians shared control with the Zakarids in various parts of the country, especially in Syunik and Vayots Dzor, while the Armenian family of Hasan-Jalalians controlled provinces of Artsakh and Utik as the Kingdom of Artsakh.". Is that enough to answer the question?
Answer: no
