Question: When was Eritrea annexed by the largest peacekeeping troop contributor to the group in which the US and creator of an Avicenna stamp in 1980 became important members?

<P0-S0> During the Middle Ages, the Eritrea region was known as Medri Bahri ("sea-land"). <P0-S1> The name Eritrea is derived from the ancient Greek name for Red Sea (Ἐρυθρὰ Θάλασσα Erythra Thalassa, based on the adjective ἐρυθρός erythros "red"). <P0-S2> It was first formally adopted in 1890, with the formation of Italian Eritrea (Colonia Eritrea). <P0-S3> Eritrea was annexed by Ethiopia in 1953 (nominally within a federation until 1962) and an Eritrean Liberation Front formed in 1960. <P0-S4> The territory became the Eritrea Governorate within Italian East Africa in 1936. <P0-S5> Eritrea gained independence following the 1993 referendum, and the name of the new state was defined as State of Eritrea in the 1997 constitution. <P0-S6> [citation needed] <SEP> <P1-S0> The Soviet Union suffered greatly in the war, losing around 27 million people. <P1-S1> Approximately 2.8 million Soviet POWs died of starvation, mistreatment, or executions in just eight months of 1941 -- 42. <P1-S2> It emerged as a superpower in the post-war period. <P1-S3> Once denied diplomatic recognition by the Western world, the Soviet Union had official relations with practically every nation by the late 1940s. <P1-S4> A member of the United Nations at its foundation in 1945, the Soviet Union became one of the five permanent members of the United Nations Security Council, which gave it the right to veto any of its resolutions. <P1-S5> During the war, the Soviet Union together with the United States, the United Kingdom and China were considered as the Big Four of Allied powers in World War II and later became the Four Policemen which was the foundation of the United Nations Security Council. <SEP> <P2-S0> In 1980, the Soviet Union, which then ruled his birthplace Bukhara, celebrated the thousandth anniversary of Avicenna's birth by circulating various commemorative stamps with artistic illustrations, and by erecting a bust of Avicenna based on anthropological research by Soviet scholars. <P2-S1> [citation needed] Near his birthplace in Qishlak Afshona, some 25 km (16 mi) north of Bukhara, a training college for medical staff has been named for him. <P2-S2> [year needed] On the grounds is a museum dedicated to his life, times and work. <P2-S3> [citation needed] <SEP> <P3-S0> In June 2013. <P3-S1> 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). <P3-S2> As of 28 February 2015, 120 countries were contributing a total of 104,928 personnel in Peacekeeping Operations, with Bangladesh leading the tally (9446). <P3-S3> 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). <P3-S4> 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. <SEP> <P4-S0> on 16 march 1934, president franklin d. roosevelt signed the migratory bird hunting stamp act, which requires an annual stamp purchase by all hunters over the age of sixteen. <P4-S1> the stamps are created on behalf of the program by the us postal service and depict wildlife artwork chosen through an annual contest. <P4-S2> they play an important role in habitat conservation because ninety-eight percent of all funds generated by their sale go directly toward the purchase or lease of wetland habitat for protection in the national wildlife refuge system. <P4-S3> [citation needed] in addition to waterfowl, it is estimated that one third of the nation's endangered species seek food and shelter in areas protected using duck stamp funds. <P4-S4> [citation needed] <SEP> <P5-S0> us troops participated in a un peacekeeping mission in somalia beginning in 1992. by 1993 the us troops were augmented with rangers and special forces with the aim of capturing warlord mohamed farrah aidid, whose forces had massacred peacekeepers from pakistan. <P5-S1> during a raid in downtown mogadishu, us troops became trapped overnight by a general uprising in the battle of mogadishu. <P5-S2> eighteen american soldiers were killed, and a us television crew filmed graphic images of the body of one soldier being dragged through the streets by an angry mob. <P5-S3> somali guerrillas paid a staggering toll at an estimated 1,000–5,000 total casualties during the conflict. <P5-S4> after much public disapproval, american forces were quickly withdrawn by president bill clinton. <P5-S5> the incident profoundly affected us thinking about peacekeeping and intervention. <P5-S6> the book black hawk down was written about the battle, and was the basis for the later movie of the same name.
