The Turkana are a Nilotic people native to the Turkana District in northwest Kenya, a semi-arid climate region bordering Lake Turkana in the east, Pokot, Rendille and Samburu people to the south, Uganda to the west, and South Sudan and Ethiopia to the north. They refer to their land as Turkan. According to the 2009 Kenyan census, Turkana number 855,399, or 2.5% of the Kenyan population, making the Turkana the third largest Nilotic ethnic group in Kenya, after the Kalenjin and the Luo, slightly more numerous than the Maasai, and the tenth largest ethnicity in all of Kenya. Although this figure was initially controversial and rejected as too large by Planning Minister Wycliffe Oparanya, a court ruling (Feb 7, 2012) by Justice Mohammed Warsame (judge) stated that the Kenyan government accepts the 2009 census figures for Turkana.
The Turkana entered Turkana basin from the north as one unit of the Ateker confederation. This cluster split as a result of internal differences, leading to the emergence of distinct independent groups. The Turkana people emerged as a victorious group in the subsequent conflict, which led to enmity between the Turkana and other Ateker cluster groups, who formed military alliances against the Turkana. The Turkana emerged victorious again by co-opting young people from conquered groups. The military power and wealth of the Turkana increased in what is now the northern plains of Turkana. The establishment of the Turkana people developed as a distinct group which expanded southwards conquering ethnic nations south of its borders. The Turkana people easily conquered groups it came in contact with by employing superior tactics of war, better weapons and military organization. By the 1600s, the Turkana basin had been fully occupied by the Turkana and their allies. There was a relative long period of peace among indigenous ethnic communities around Turkana until the onset of European colonization of Africa. Sporadic conflicts involved Turkana fights against Arab, Swahili and Abyssinian slave raiders and ivory traders. European colonization brought a new dimension to conflict with Turkana putting up a lasting resistance to a complex enemy, the British. The Turkana put up and maintained active resistance to British colonial advances leading to a passive presence of colonial administration. By the outbreak of World War I, few parts of Turkana had been put under colonial administration. From World War I through to the end of World War II, Turkana actively participated in the wars as allies of Britain against invading Italy. Turkana was used as the launching pad for the war against invading Italian forces leading to the liberation of Abyssinia. After World War II, the British led disarmament and pacification campaigns in Turkana, leading to massive disruptions and dispossession of Turkana pastoralists. The colonial administration practiced a policy of deliberate segregation of Turkana people by categorizing Turkana Province as a closed district. This led to marginalization and underdevelopment in the lead up to Kenya's independence.

What is historical about the Turkana people?

The Turkana people easily conquered groups it came in contact with by employing superior tactics of war, better weapons and military organization.

Morten Per Olsen (born 14 August 1949) is a Danish football manager and former football player. He was the head coach of the Danish national team for 15 years from 2000 until 2015, guiding Denmark to the 2002 FIFA World Cup, 2004 European Championship, 2010 FIFA World Cup and 2012 European Championship. He has also managed Brondby IF to two Danish Superliga championships and Ajax to the Double of the 1998 Dutch Eredivisie championship and Dutch Cup trophy.
Olsen made his debut for the Denmark under-21 national team in September 1970, scoring a single goal in a 2-2 friendly match draw with the Poland U21s. Three weeks later, he was called up for the senior Danish national team under the Austrian national team manager Rudi Strittich, and Olsen made his national team debut in September 1970 against Norway. He played his first national team game as a right winger, but eventually settled as a defensive midfielder. He helped Denmark qualify for the 1972 Summer Olympics, but could not participate at the tournament, as he had signed a professional contract with Cercle Brugge beforehand. While at Anderlecht, Olsen became the seventh Dane to play 50 games for the national team, in June 1981. For Olsen's 53rd national team game in April 1983, the German national team manager of Denmark, Sepp Piontek, named Olsen permanent national team captain, as Olsen replaced the retiring Per Rontved as both libero and team captain. Olsen played as an attacking libero, and had defensive midfielder Jens Jorn Bertelsen cover for him when he was on the attack. Olsen, alongside defender Soren Busk, persuaded Piontek to implement the aggressive off-side trap they practiced at Anderlecht. Olsen captained the Danish team that qualified for the 1984 European Championship; Denmark's first international tournament participation since the 1972 Olympics. Denmark reached the semi-finals, before being eliminated by Spain on penalty shootout. In October 1985, Olsen became the second Dane, after Per Rontved, to play 75 national team matches. He captained Denmark at the 1986 World Cup, Denmark's first World Cup participation, which ended in a second round defeat to Spain. Olsen's most noticeable effort at the tournament came in the 2-0 group stage win against West Germany. He took the ball from his own half and made an irresistible dribbling run that was only stopped by a foul in the West German penalty area, with Jesper Olsen scoring the 1-0 goal on the resulting penalty kick. Olsen was identified as one of the overall top performers at the World Cup, and he was subsequently named 1986 Danish Player of the Year. While he was moved to a midfielder position at Koln, Olsen continued to play as a libero for Denmark. He captained Denmark at the 1988 European Championship, which ended in the preliminary group stage. During the tournament, Olsen proved too slow for the libero position, and was moved up as defensive midfielder, leaving the libero position for Lars Olsen. Morten Olsen ended his international career following the 1988 European Championship, having played 99 national team games, but was called up again 10 months later. Olsen became the first Dane to play 100 games for the national team in April 1989, before ending his national team career in June 1989. Olsen played a record 102 games and scored four goals for the national team, and set a record of 50 games as Danish national team captain. His team captain record was broken by Lars Olsen in 1992, while his game tally was bested by Peter Schmeichel in 1998. In his entire international career, Morten Olsen only got one yellow card.

What was his greatest international success?
Olsen became the seventh Dane to play 50 games for the national team, in June 1981.
