full_context: Document 1: Sierra Leone Civil War: The Sierra Leone Civil War (1991 -- 2002) began on 23 March 1991 when the Revolutionary United Front (RUF), with support from the special forces of Charles Taylor's National Patriotic Front of Liberia (NPFL), intervened in Sierra Leone in an attempt to overthrow the Joseph Momoh government. The resulting civil war lasted 11 years, enveloped the country, and left over 50,000 dead.
Document 2: Israel: Israel was established as a homeland for the Jewish people and is often referred to as a Jewish state. The country's Law of Return grants all Jews and those of Jewish ancestry the right to Israeli citizenship. Over three quarters, or 75.5%, of the population are Jews from a diversity of Jewish backgrounds. Around 4% of Israelis (300,000), ethnically defined as "others", are Russian descendants of Jewish origin or family who are not Jewish according to rabbinical law, but were eligible for Israeli citizenship under the Law of Return. Approximately 75% of Israeli Jews are born in Israel, 17% are immigrants from Europe and the Americas, and 8% are immigrants from Asia and Africa (including the Arab World). Jews from Europe and the former Soviet Union and their descendants born in Israel, including Ashkenazi Jews, constitute approximately 50% of Jewish Israelis. Jews who left or fled Arab and Muslim countries and their descendants, including both Mizrahi and Sephardi Jews, form most of the rest of the Jewish population. Jewish intermarriage rates run at over 35% and recent studies suggest that the percentage of Israelis descended from both Sephardi and Ashkenazi Jews increases by 0.5 percent every year, with over 25% of school children now originating from both communities.
Document 3: Eritrea: Eritrea's ethnic groups each have their own styles of music and accompanying dances. Amongst the Tigrinya, the best known traditional musical genre is the guaila. Traditional instruments of Eritrean folk music include the stringed krar, kebero, begena, masenqo and the wata (a distant/rudimentary cousin of the violin). The most popular Eritrean artist is the Tigrinya singer Helen Meles, who is noted for her powerful voice and wide singing range. Other prominent local musicians include the Kunama singer Dehab Faytinga, Ruth Abraha, Bereket Mengisteab, Yemane Baria, and the late Abraham Afewerki.
Document 4: Somalis: The textile-making communities in Somalia are a continuation of an ancient textile industry, as is the culture of wood carving, pottery and monumental architecture that dominates Somali interiors and landscapes. The cultural diffusion of Somali commercial enterprise can be detected in its cuisine, which contains Southeast Asian influences. Due to the Somali people's passionate love for and facility with poetry, Somalia has often been referred to by scholars as a "Nation of Poets" and a "Nation of Bards" including, among others, the Canadian novelist Margaret Laurence.
Document 5: Somalis: Somalis have a rich musical heritage centered on traditional Somali folklore. Most Somali songs are pentatonic. That is, they only use five pitches per octave in contrast to a heptatonic (seven note) scale, such as the major scale. At first listen, Somali music might be mistaken for the sounds of nearby regions such as Ethiopia, Sudan or Arabia, but it is ultimately recognizable by its own unique tunes and styles. Somali songs are usually the product of collaboration between lyricists (midho), songwriters (lahan) and singers ('odka or "voice").
Document 6: Somalis: All of these traditions, including festivals, martial arts, dress, literature, sport and games such as Shax, have immensely contributed to the enrichment of Somali heritage.
Document 7: Demographics of Israel: According to Israel's Central Bureau of Statistics, in 2008, of Israel's 7.3 million people, 75.6 percent were Jews of any background. Among them, 70.3 percent were Sabras (born in Israel), mostly second- or third-generation Israelis, and the rest are olim (Jewish immigrants to Israel)—20.5 percent from Europe and the Americas, and 9.2 percent from Asia and Africa, including the Arab countries.The paternal lineage of the Jewish population of Israel as of 2015 is as follows:
Document 8: Liberia: The rebels soon split into various factions fighting one another. The Economic Community Monitoring Group under the Economic Community of West African States organized a military task force to intervene in the crisis. From 1989 to 1996 one of Africa's bloodiest civil wars ensued, claiming the lives of more than 200,000 Liberians and displacing a million others into refugee camps in neighboring countries. A peace deal between warring parties was reached in 1995, leading to Taylor's election as president in 1997.
Document 9: Jews: Between 1948 and 1958, the Jewish population rose from 800,000 to two million. Currently, Jews account for 75.4% of the Israeli population, or 6 million people. The early years of the State of Israel were marked by the mass immigration of Holocaust survivors in the aftermath of the Holocaust and Jews fleeing Arab lands. Israel also has a large population of Ethiopian Jews, many of whom were airlifted to Israel in the late 1980s and early 1990s. Between 1974 and 1979 nearly 227,258 immigrants arrived in Israel, about half being from the Soviet Union. This period also saw an increase in immigration to Israel from Western Europe, Latin America, and North America.
Document 10: Mali: Malian musical traditions are derived from the griots, who are known as "Keepers of Memories". Malian music is diverse and has several different genres. Some famous Malian influences in music are kora virtuoso musician Toumani Diabaté, the late roots and blues guitarist Ali Farka Touré, the Tuareg band Tinariwen, and several Afro-pop artists such as Salif Keita, the duo Amadou et Mariam, Oumou Sangare, and Habib Koité. Dance also plays a large role in Malian culture. Dance parties are common events among friends, and traditional mask dances are performed at ceremonial events.

Document 12: Israel: In 2016, Israel's population was an estimated 8,476,600 million people, of whom 6,345,400 (74.9%) were recorded by the civil government as Jews. 1,760,400 Arabs comprised 20.7% of the population, while non-Arab Christians and people who have no religion listed in the civil registry made up 4.4%. Over the last decade, large numbers of migrant workers from Romania, Thailand, China, Africa, and South America have settled in Israel. Exact figures are unknown, as many of them are living in the country illegally, but estimates run in the region of 203,000. By June 2012, approximately 60,000 African migrants had entered Israel. About 92% of Israelis live in urban areas.

In addition, Israel is home to over 5,000 members of the African Hebrew Israelites of Jerusalem movement that are descendants of African Americans who emigrated to Israel in the 20th century, and who reside mainly in a distinct neighborhood in the Negev town of Dimona. Unknown numbers of black converts to Judaism reside in Israel, most of them converts from the United Kingdom, Canada, and the United States.
