I want to know the answer to the following question:
Who established the Arsacid dynasty of Armenia?
All the background I'm provided with is that "In the next centuries, Armenia was in the Persian Empire's sphere of influence during the reign of Tiridates I, the founder of the Arsacid dynasty of Armenia, which itself was a branch of the eponymous Arsacid dynasty of Parthia.". Is that enough to answer the question?
Answer: yes
