immigration of Israeli citizens to the region and the two-state solution there was no formal government or authority in the land known as Palestine. Society operated without a democracy, monarchy or dictatorship; merely a conglomerate of tribes, clans, villages and communities headed by a select few elders known as "Sheikhs" also transliterated Sheik, Sheyikh, Shaykh, Shayk, Cheikh, Shekh, Shaik and Shaikh. The two state solution drastically altered this and effectively displaced an overwhelming amount of Palestinians. As a result, the semi-political organization, Palestinian Liberation Organization (PLO) was formed. Yasser Arafat served as chairman of the Palestine Liberation Organization from 1969 to 2004 and is considered one of the most influential Palestinian leaders. Arab Spring The protests, uprisings and revolutions in the Middle East and North Africa, beginning on 18 December 2010, brought about the overthrow of the Tunisian and Egyptian governments. Libya was brought into a 6-month civil war which brought about the end of Gaddafi's 41-year rule. Bahrain and Yemen experienced uprisings. The uprising in Syria led to full-scale civil war. Tunisia and Egypt have held elections that were considered fair by observers. Mohamed Morsi was sworn in as Egypt's first president to gain power through an election on 30 June 2012; however, after protests against him in June 2013, as well as a 48-hour deadline by the Egyptian Armed Forces to respond to the protesters' demands that he did not comply with, Morsi was removed from office in July 2013. Morsi's Defence Minister, Abdel Fattah el-Sisi, who served as a general in the Egyptian Armed Forces at the time, was responsible for announcing the overthrow on state television. Many other countries in the region are also calling for democracy and freedom, including: Algeria, Armenia, Azerbaijan, Djibouti, Iran, Iraq, Jordan, Oman, Yemen, Kuwait, Mauritania, Morocco, Saudi Arabia, Sudan and Turkey. Research confirms that (in general) people in Islamic societies support democracy. Secularism Secularism in the Middle East was pioneered by Mustafa Kemal Atatürk, who, though he himself had some authoritarian tendencies, helped establish the first modern Middle Eastern secular democracy in Turkey. Arab Socialism has also fostered secularism, though sometimes in what has been seen as a less democratic context. Secularism is not the same as freedom of religion, and secular governments have at times denied the rights of Islamists and other religious parties. This is essentially why Mustafa Kemal Atatürk was such a polarizing figure among the Turks.
