I want to know the answer to the following question:
When did Attalus III die?
All the background I'm provided with is that "The Attalid dynasty of Pergamum lasted little longer; a Roman ally until the end, its final king Attalus III died in 133 BC without an heir, and taking the alliance to its natural conclusion, willed Pergamum to the Roman Republic.". Is that enough to answer the question?
Answer: yes
