Rebels Inside Muammar Muhammad Al-Gaddafi Villas, Libya

On 1 September 1969 a small group of junior military officers led by Gaddafi staged a bloodless coup d'état against King Idris while he was in Turkey for medical treatment. His nephew, the Crown Prince Sayyid Hasan ar-Rida al-Mahdi as-Sanussi, was formally deposed by the revolutionary army officers and put under house arrest; they abolished the monarchy and proclaimed the Libyan Arab Republic.
Ideology
On the Muslim prophet Muhammad's birthday in 1973, Gaddafi delivered his famous "Five-Point Address" which officially implemented Sharia. Gaddafi's ideology was largely based on Nasserism, blending Arab nationalism, aspects of the welfare state, and what Gaddafi termed "popular democracy", or more commonly "direct, popular democracy". He called this system "Islamic socialism", as he disfavored the atheistic quality of communism. While he permitted private control over small companies, the government controlled the larger ones. Welfare, "liberation" (or "emancipation" depending on the translation), and education was emphasized. He also imposed a system of Islamic morals and outlawed alcohol and gambling. School vacations were canceled to allow the teaching of Gaddafi's ideology in the summer of 1973.
