full_context: Document 1: United Nations Population Fund: Contributions from governments and the private sector to UNFPA in 2014 exceeded $1 billion. The amount includes $477 million to the organization’s core resources and $529 million earmarked for specific programs and initiatives.
Document 2: Cyprus: Cyprus was placed under British administration based on Cyprus Convention in 1878 and formally annexed by Britain in 1914. Even though Turkish Cypriots made up only 18% of the population, the partition of Cyprus and creation of a Turkish state in the north became a policy of Turkish Cypriot leaders and Turkey in the 1950s. Turkish leaders for a period advocated the annexation of Cyprus to Turkey as Cyprus was considered an "extension of Anatolia" by them; while since the 19th century, the majority Greek Cypriot population and its Orthodox church had been pursuing union with Greece, which became a Greek national policy in the 1950s. Following nationalist violence in the 1950s, Cyprus was granted independence in 1960. In 1963, the 11-year intercommunal violence between Greek Cypriots and Turkish Cypriots started, which displaced more than 25,000 Turkish Cypriots and brought the end of Turkish Cypriot representation in the republic. On 15 July 1974, a coup d'état was staged by Greek Cypriot nationalists and elements of the Greek military junta in an attempt at enosis, the incorporation of Cyprus into Greece. This action precipitated the Turkish invasion of Cyprus, which led to the capture of the present-day territory of Northern Cyprus the following month, after a ceasefire collapsed, and the displacement of over 150,000 Greek Cypriots and 50,000 Turkish Cypriots. A separate Turkish Cypriot state in the north was established in 1983. These events and the resulting political situation are matters of a continuing dispute.
Document 3: Eritrea: During the Middle Ages, the Eritrea region was known as Medri Bahri ("sea-land"). The name Eritrea is derived from the ancient Greek name for Red Sea (Ἐρυθρὰ Θάλασσα Erythra Thalassa, based on the adjective ἐρυθρός erythros "red"). It was first formally adopted in 1890, with the formation of Italian Eritrea (Colonia Eritrea). The territory became the Eritrea Governorate within Italian East Africa in 1936. Eritrea was annexed by Ethiopia in 1953 (nominally within a federation until 1962) and an Eritrean Liberation Front formed in 1960. Eritrea gained independence following the 1993 referendum, and the name of the new state was defined as State of Eritrea in the 1997 constitution.[citation needed]
Document 4: List of members of the United Nations Security Council: As of July 2011, there are currently 193 members of the United Nations and five permanent members of the Security Council. The other ten seats are assigned amongst the remaining 188 members. As a result, many members have never been on the Security Council. The following list is a summary of all countries, currently 68 modern nations and three historical ones, that have never been a member of the United Nations Security Council. The three historical UN members listed are Tanganyika, Zanzibar, and the Federal Republic of Yugoslavia.
Document 5: Eritrea: Eritrea (/ˌɛrᵻˈtreɪ.ə/ or /ˌɛrᵻˈtriːə/;, officially the State of Eritrea, is a country in East Africa. With its capital at Asmara, it is bordered by Sudan in the west, Ethiopia in the south, and Djibouti in the southeast. The northeastern and eastern parts of Eritrea have an extensive coastline along the Red Sea. The nation has a total area of approximately 117,600 km2 (45,406 sq mi), and includes the Dahlak Archipelago and several of the Hanish Islands. Its name Eritrea is based on the Greek name for the Red Sea (Ἐρυθρὰ Θάλασσα Erythra Thalassa), which was first adopted for Italian Eritrea in 1890.
Document 6: Cyprus: International pressure led to a ceasefire, and by then 37% of the island had been taken over by the Turks and 180,000 Greek Cypriots had been evicted from their homes in the north. At the same time, around 50,000 Turkish Cypriots moved to the areas under the control of the Turkish Forces and settled in the properties of the displaced Greek Cypriots. Among a variety of sanctions against Turkey, in mid-1975 the US Congress imposed an arms embargo on Turkey for using American-supplied equipment during the Turkish invasion of Cyprus in 1974. There are 1,534 Greek Cypriots and 502 Turkish Cypriots missing as a result of the fighting.
Document 7: Cyprus: The Turkish invasion, followed by occupation and the declaration of independence of the TRNC have been condemned by United Nations resolutions, which are reaffirmed by the Security Council every year. The last major effort to settle the Cyprus dispute was the Annan Plan in 2004, drafted by the then Secretary General, Kofi Annan. The plan was put to a referendum in both Northern Cyprus and the Republic of Cyprus. 65% of Turkish Cypriots voted in support of the plan and 74% Greek Cypriots voted against the plan, claiming that it disproportionately favoured the Turkish side. In total, 66.7% of the voters rejected the Annan Plan V. On 1 May 2004 Cyprus joined the European Union, together with nine other countries. Cyprus was accepted into the EU as a whole, although the EU legislation is suspended in the territory occupied by Turkey (TRNC), until a final settlement of the Cyprus problem. In July 2006, the island served as a haven for people fleeing Lebanon, due to the conflict between Israel and Hezbollah (also called "The July War").
Document 8: Eritrea: In 1922, Benito Mussolini's rise to power in Italy brought profound changes to the colonial government in Italian Eritrea. After il Duce declared the birth of the Italian Empire in May 1936, Italian Eritrea (enlarged with northern Ethiopia's regions) and Italian Somaliland were merged with the just conquered Ethiopia in the new Italian East Africa (Africa Orientale Italiana) administrative territory. This Fascist period was characterized by imperial expansion in the name of a "new Roman Empire". Eritrea was chosen by the Italian government to be the industrial center of Italian East Africa.
Document 9: Eritrea: The Scottish traveler James Bruce reported in 1770 that Medri Bahri was a distinct political entity from Abyssinia, noting that the two territories were frequently in conflict. The Bahre-Nagassi ("Kings of the Sea") alternately fought with or against the Abyssinians and the neighbouring Muslim Adal Sultanate depending on the geopolitical circumstances. Medri Bahri was thus part of the Christian resistance against Imam Ahmad ibn Ibrahim al-Ghazi of Adal's forces, but later joined the Adalite states and the Ottoman Empire front against Abyssinia in 1572. That 16th century also marked the arrival of the Ottomans, who began making inroads in the Red Sea area.
Document 10: United Nations Population Fund: In response, the EU decided to fill the gap left behind by the US under the Sandbaek report. According to its Annual Report for 2008, the UNFPA received its funding mainly from European Governments: Of the total income of M845.3 M, $118 was donated by the Netherlands, $67 M by Sweden, $62 M by Norway, $54 M by Denmark, $53 M by the UK, $52 M by Spain, $19 M by Luxembourg. The European Commission donated further $36 M. The most important non-European donor State was Japan ($36 M). The number of donors exceeded 180 in one year.
Document 11: United Nations peacekeeping: As of 29 February 2016, 124 countries were contributing a total of 105,314 personnel in Peacekeeping Operations, with Ethiopia leading the tally (8,324), followed by India (7,695) and Bangladesh (7,525). In June 2013. Pakistan contributed the highest number overall with 8,186 personnel, followed by India (7,878), Bangladesh (7,799), Ethiopia (6,502), Rwanda (4,686), Nigeria (4,684), Nepal (4,495), Jordan (3,374), Ghana (2,859), and Egypt (2,750). As of 28 February 2015, 120 countries were contributing a total of 104,928 personnel in Peacekeeping Operations, with Bangladesh leading the tally (9446). As of March 2008, in addition to military and police personnel, 5,187 international civilian personnel, 2,031 UN Volunteers and 12,036 local civilian personnel worked in UN peacekeeping missions.
Document 12: Cyprus: The events of the summer of 1974 dominate the politics on the island, as well as Greco-Turkish relations. Around 150,000 settlers from Turkey are believed to be living in the north—many of whom were forced from Turkey by the Turkish government—in violation of the Geneva Convention and various UN resolutions. Following the invasion and the capture of its northern territory by Turkish troops, the Republic of Cyprus announced that all of its ports of entry in the north were closed, as they were effectively not under its control.[citation needed]
Document 13: Eritrea: The creation of modern-day Eritrea is a result of the incorporation of independent, distinct kingdoms and sultanates (for example, Medri Bahri and the Sultanate of Aussa) eventually resulting in the formation of Italian Eritrea. In 1947 Eritrea became part of a federation with Ethiopia, the Federation of Ethiopia and Eritrea. Subsequent annexation into Ethiopia led to the Eritrean War of Independence, ending with Eritrean independence following a referendum in April 1993. Hostilities between Eritrea and Ethiopia persisted, leading to the Eritrean–Ethiopian War of 1998–2000 and further skirmishes with both Djibouti and Ethiopia.
Document 14: Cyprus: Since 1965, following clashes between the two communities, the Turkish Cypriot seats in the House remain vacant. In 1974 Cyprus was divided de facto when the Turkish army occupied the northern third of the island. The Turkish Cypriots subsequently declared independence in 1983 as the Turkish Republic of Northern Cyprus but were recognised only by Turkey. In 1985 the TRNC adopted a constitution and held its first elections. The United Nations recognises the sovereignty of the Republic of Cyprus over the entire island of Cyprus.
