I want to know the answer to the following question:
When did the Seljuk Empire experience it's decline?
All the background I'm provided with is that "In the early 12th century, Armenian princes of the Zakarid noble family drove out the Seljuk Turks and established a semi-independent Armenian principality in Northern and Eastern Armenia, known as Zakarid Armenia, which lasted under the patronage of the Georgian Kingdom.". Is that enough to answer the question?
Answer: yes
