I want to know the answer to the following question:
Who was the first king of Artaxiad dynasty of Armenia?
All the background I'm provided with is that "After the Seleucid defeat at the Battle of Magnesia in 190 BC, the kings of Sophene and Greater Armenia revolted and declared their independence, with Artaxias becoming the first king of the Artaxiad dynasty of Armenia in 188.". Is that enough to answer the question?
Answer: yes
