Iran is a Middle Eastern nation with a population of just over 77 million. Iran’s population is predominately Persian, and Persian is the official language. The Shia branch of Islam is the official state religion, and approximately 90-95 percent of the population belongs to the faith. The second-largest nation in the region, Iran contains some of the world’s largest oil and gas reserves. The energy industry makes up a large portion of Iran’s economy, and the nation is one of the founding members of the Organization of the Petroleum Exporting Countries (OPEC).

The Islamic Republic of Iran is the world's only remaining theocratic state, in which political leadership is vested in religious authorities. The Islamic Republic was created in 1979 following a revolution against the Shah of Iran, Mohammad Reza Shah Pahlavi. Although many elements of Iranian society led the revolution, ultimately Ayatollah Ruhollah Khomeini and his followers gained control of the country. In December 1979, the country adopted an Islamic constitution providing that “all civil, criminal, financial, economic, administrative, cultural, military, political and all other statutes and regulations be in keeping with Islamic [law].”

Following adoption of the new constitution, Khomeini became the “Supreme Leader,” the ultimate political and religious authority in the country. Ayatollah Sayyid Ali Hoseyni Khamenei has been Supreme Leader since Khomeini’s death in 1989. The Supreme Leader is selected by a body of Islamic scholars called the Assembly of Experts. The Supreme Leader is responsible for the military and security concerns of Iran and has the final say on all issues. The president of Iran, who is elected by the public from a list approved by the Guardian Council (a body comprised of clerics and jurists), is nominally responsible for administration of the executive branch and is subject to the authority of the Supreme Leader.

Mahmoud Ahmadinejad was elected president in 2005. Ahmadinejad was viewed as an ultraconservative and his views a stark contrast from the relatively reformist policies of his predecessor, President Mohammad Khatami. Despite promises of equality and fighting corruption, Ahmadinejad and his administration cracked down on civil liberties and more strictly enforced religious-based morality laws.

Ahmadinejad was reelected in 2009 in an election widely viewed as fraudulent. Following the June 2009 election, hundreds of thousands of Iranians took to the streets in the largest protests in the country since 1979, which came to be known as the “Green Revolution.” The government responded to the peaceful protestors with a massive campaign of intimidation, violence, and limits on freedoms. Universities were closed down, media outlets and internet resources censored, and rights to assembly restricted.

In June 2013, Hassan Rouhani was elected President and replaced Ahmadinejad. Rouhani has a reputation as a relatively moderate reformer and has promised additional freedoms and rights. It remains to be seen whether or not these promises will be fulfilled.

According to Freedom House, Iran is one of the least-free countries in the world. In its most recent report, Iran received a score of six in both the political rights and civil liberties categories, where one represents most free and seven represents least free. Iran has been the subject of numerous resolutions at the United Nations condemning the country’s human rights record. Among other things, the government uses summary arrest and execution against its political opponents. The death penalty is applied even for nonviolent crimes, including adultery. Radio and television broadcasting are under the control of the government and provide only government-approved content. Women are denied equal rights in marriage and other areas.

With a history dating back to the 10th millennium B.C., Egypt has long played a central role in the Middle East. Egypt is the largest Arab nation and has an influential voice in Arabic and Middle Eastern culture. Egypt has a diverse economy, but has struggled to create sustained economic growth and opportunities for its population of 84 million people.

The country has little experience with representative democracy. From 1956 to 1970, President Gamal Abdel Nasser ruled Egypt with a strong hand, nationalizing the Suez Canal and taking the country into conflict with the new state of Israel. Upon his death, Anwar al-Sadat became president. Together with other Arab nations, Sadat launched the October War against Israel in 1973. In 1979, Sadat signed a groundbreaking peace treaty with Israel.

From Sadat’s assassination in 1981 until the 2011 Egyptian Revolution, Egypt was governed by President Hosni Mubarak. For all of Mubarak’s time in office, and for much of the time since his resignation, Egypt has been under “Emergency Law,” which allows the government to suspend constitutional rights, including limiting political activity and restricting free speech. Emergency Law also allows the government to use summary arrests against political opponents.

For four successive terms, Mubarak was reelected in referenda without an opponent. In 2005, under domestic and international pressure, Mubarak proposed a constitutional amendment to allow Egypt’s first multicandidate presidential elections. Because the amendment would have imposed severe restrictions on the eligibility of opposition candidates, opposition groups boycotted the vote. Mubarak claimed to have won the September 2005 presidential election with an official 88 percent of the vote, amid widespread allegations of fraud and vote rigging. The main opposition leader, Ayman Nour, was subsequently prosecuted by the government for forging signatures on petitions and was sentenced to five years in prison, provoking protests from the United States and other democratic countries.

Following the example of the Tunisian Revolution, large protests swept Egypt in early 2011. The military, led by the Supreme Council of the Armed Forces (SCAF), withdrew its support of Mubarak. On February 11, 2011, Vice President Omar Suleiman announced that Mubarak had resigned. The Supreme Council of the Armed Forces (SCAF) headed by Field Marshal Mohamed Hussein Tantawi then assumed power in Egypt. SCAF dissolved the parliament and suspended the constitution.

In November 2011, Egypt held parliamentary elections that were reportedly fair and democratic. In June 2012, Muslim Brotherhood leader Mohamed Morsi was elected President, in part because liberal and secular forces failed to coalesce around a single candidate. Morsi’s popularity declined as he declared his orders immune from challenge, removed judicial review processes, and was accused of taking steps towards the implementation of Islamist policies. Conflict arose between those supporting Islamist policies and those seeking a more liberal and secular government. Protests occurred throughout his presidency until Morsi was ousted by the military in July 2013. Muslim Brotherhood leaders were arrested and their camps and offices raided. Until new elections are held, a SCAF-installed provisional government led by acting President Adly Mansour is in control.

In its most recent report, the independent watchdog group Freedom House classifies Egypt as “partly free.” On its scale where 1 is the most free and 7is the least free, Egypt earned scores of 5 in both the civil liberties and political rights categories.

Syria is bordered by Turkey, Iraq, Jordan, Israel, Lebanon, and the Mediterranean Sea. It emerged from the Ottoman Empire in 1918 as a protectorate of France, reaching full independence in 1946. Its population of 22 million consists of many ethnic groups. Approximately 70 percent are Sunni Muslims, 13 percent are Shia Muslims, and 10 percent are Christians. Syria had a lower middle income economy prior to the civil war, where the state played a dominant role.

The Syrian Arab Republic originated as a secular, socialist state dominated by the Ba’ath party, an Arab nationalist movement. The state has since evolved into an autocracy headed by a single family and dominated by members of the minority Alawite sect, a branch of Shia Islam.

The Ba’ath Party took power in Syria in a series of coups d’état in the 1960s and 1970s. One of the leaders of those coups, Hafez al-Assad, became president in 1971 and led the country until his death in 2000. Under Assad, Alawites assumed control over the state security forces. In 1982, Assad’s forces stormed the city of Hama to brutally suppress a Sunni rebellion, killing thousands of civilians.

Following the death of Hafez al-Assad, his son, Bashar al-Assad, was elected president by a referendum in which he ran unopposed, officially garnering 97 percent of the vote. He was reelected in 2007, again with 97 percent of the vote.

The Syrian government is one of the world’s most brutal and restrictive. From 1963 to 2011, the government operated under an “Emergency Law,” which suspended many constitutional protections of civil liberties. The government continues to use arbitrary detention and torture against political opponents, and operates through an extensive internal security apparatus, including secret police. The government controls most of the country’s media outlets, and access to the Internet is permitted only through state-operated servers. The minority Kurdish population has been continually discriminated against and repressed.

Influenced by movements in Egypt and Tunisia, large opposition protests took place across Syria in 2011. The government responded with a harsh crackdown. Security forces fired on protestors, killing thousands. The crackdown led the Arab League to suspend Syria’s membership. The Assad regime attempted to appease dissenters through a series of low-level and largely inconsequential reforms in 2011 and 2012. However, the conflict has escalated into full-fledged civil war with both liberal and Islamic militias being formed to fight against the Assad regime. The Assad regime has continued to attempt to defeat the opposition using air strikes and heavy artillery to attack rebel-held neighborhoods. Freedoms of association, assembly, and the press were restricted even further as the government attempted to quell the uprising. Over a million people have been either internally displaced or fled the country as refugees.

In the summer of 2013, it was confirmed that the Syrian government had used chemical weapons to attack civilians. Over 600 people were killed in one such attack in the Ghouta suburb of Damascus using a nerve agent confirmed to be sarin. The Assad regime’s use of chemical weapons drew international attention and resulted in a renewed international focus on the nation and its civil conflict.

Freedom House rates Syria as “not free” noting that conditions even prior to the 2011 uprising and subsequent civil war were, at best, abysmal. It earned the worst possible ratings of seven in both the political rights and civil liberties categories. Conditions since the 2011 uprising have only deteriorated, and civil freedoms are restricted under the fear of violence. Freedom House has also expressed concern over rising sectarian tensions and massive displacement.

Tunisia is situated on the Mediterranean coastline. It has a population of fewer than 11 million people and is the smallest nation in North Africa in land area. In 2010 and 2011, it became the first of the Arab countries to revolt against decades of dictatorial rule, launching the Arab Spring and a wave of change across the region. Tunisia has a developing economy, focused largely on agriculture, tourism, and light industry.

Tunisia has been settled since ancient times. In the 10th century B.C., it was part of the Phoenician Empire. The city of Carthage, near the modern capital of Tunis, was established in the 9th century B.C. In 149 B.C., the Roman Empire conquered the Phoenicians. Islam was introduced to what is now Tunisia in the 7th century A.D., and the area formed part of the Ottoman Empire for centuries. In 1881, Tunisia became a protectorate of France. A strong French cultural element continues to this day.

In 1956, Habib Bourguiba led Tunisia to independence from France. His political party, later known as the Constitutional Democratic Rally, went on to dominate Tunisian politics for more than 50 years. Bourguiba’s Tunisia was a largely secular state and was viewed as one of the most progressive in the Arab world on women’s issues. In 1987, Bourguiba was replaced in a “bloodless coup” by his prime minister, Zine El Abidine Ben Ali. Ben Ali continued many of Bourguiba’s policies, but ruled with an increasingly heavy hand. The Ben Ali regime was repressive and corrupt, with a dismal human rights record. The regime showed little tolerance for dissent, and lashed out at opposition voices in politics, civil society, and the media.

The Tunisian Revolution began in December 2010, when Mohamed Bouazizi, a young street vendor, set himself on fire in protest over harassment by a local official. Bouazizi’s act led to mass demonstrations across the country, protesting the lack of human rights, poor economic conditions, and corruption and nepotism in the Ben Ali regime. On January 14, 2011, Ben Ali stepped down and fled the country. On October 23, 2011, Tunisia held its first free elections, forming a Constituent Assembly to draft a new constitution and lead the country to general elections. The role of religion in society is among the most important issues facing the assembly and country.

Under the interim Constituent Assembly, Tunisia has experienced considerable political upheaval, but has begun to consolidate its democracy. There is a major fault line between Islamist and secular political forces. In 2013, several political assassinations resulted in widespread protests and demonstrators calling for the nation’s Islamist-led government to be removed. In January of 2014, after two years of debate, the Constituent Assembly ratified the nation’s new constitution. The constitution is considered progressive for the nation and has many human rights guarantees. With the ratification of the constitution, elections are scheduled for autumn 2014.

Freedom House’s 2013 Freedom in the World report categorized Tunisia as “partly free”. The nation received the following ratings on a scale with one being the most free and seven being the least: 3.5 as an overall freedom rating, a four in civil liberties and a three in political rights. Tunisia’s Internet and press were also categorized as “partly free” in subsequent Freedom House reports.
