I want to know the answer to the following question:
When did Gaddafi rule as the "Brotherly Leader"?
All the background I'm provided with is that "He governed Libya as Revolutionary Chairman of the Libyan Arab Republic from 1969 to 1977 and then as the "Brotherly Leader" of the Great Socialist People's Libyan Arab Jamahiriya from 1977 to 2011.". Is that enough to answer the question?
Answer: yes
