I want to know the answer to the following question:
What year did the first of the two heads of state die?
All the background I'm provided with is that "Tupua Tamasese Mea'ole died in 1963, leaving Malietoa Tanumafili II sole head of state until his death on 11 May 2007, upon which Samoa changed from a constitutional monarchy to a parliamentary republic de facto.". Is that enough to answer the question?
Answer: yes
