Question: Both Genghis Blues and To Shoot an Elephant are considered what type of film?
Context: Chinggis Square (Mongolian: Чингисийн талбай , pronounced "Chinggisiin Talbai"), formally Grand Chinggis Khaan Square, and previously known as (and still commonly referred to as) Sükhbaatar Square (Mongolian: Сүхбаатарын талбай , pronounced "Sükhbaatariin Talbai"), is the central square of Mongolia's capital Ulaanbaatar.  The official name was changed in 2013 in honor of Genghis Khan, considered the founding father of Mongolia.  The city's residents still refer it by the original name.  A large colonnade monument to Genghis Khan, as well as to Ögedei Khan, and Kublai Khan dominates the square's north side directly in front of the Saaral Ordon (Government Palace).  The center of the square features an equestrian statue of Damdin Sükhbaatar, one of the leaders of Mongolia's 1921 revolution. The Burkhan Khaldun (Cyrillic: Бурхан Халдун) is one of the Khentii Mountains in the Khentii Province of northeastern Mongolia.  The mountain or its locality is believed to be the birthplace of Genghis Khan as well as the location of his tomb.  It is also the birthplace of one of his most successful generals; Subutai.  The mountain is part of the 12000 km2 Khan Khentii Strictly Protected Area established in 1992.  It had strong religious significance before Genghis Khan made it a powerful landmark, but is considered the most sacred mountain in Mongolia since it was designated as sacred by Genghis Khan.  It was inscribed as a UNESCO World Heritage Site on 4 July 2015 under the title "Great Burkhan Khaldun Mountain and its surrounding sacred landscape."  Under a Presidential Decree of 1955 the worship of this mountain has been formalised and the mountain declared a national monument.  Its ecosystem is complex with unique biodiversity with flora of the Central Asian steppe.  It has 50 species of fauna and 253 species of birds. Roko Belic is an American film producer and director.  His directorial debut, "Genghis Blues", was nominated for an Academy Award for best documentary feature. Chagatai Khan　(Mongolian: Цагадай , "Tsagadai"; , "Chágětái"; Turkish: "Çağatay" ; Persian: , "Joghatai" , 22 December 1183 – 1 July 1242) was the second son of Genghis Khan.  He was Khan of the Chagatai Khanate from 1226-1242 C.E.  The Chagatai language and Chagatai Turks take their names from him.  He inherited most of what are now the five Central Asian states after the death of his father.  He was also appointed by Genghis Khan to oversee the execution of the Yassa, the written code of law created by Genghis Khan, though that lasted only until Genghis Khan was crowned Khan of the Mongol Empire.  The Empire later came to be known as the Chagatai Khanate, a descendant empire of the Mongol Empire.  Chagatai Khan was considered hot-headed and somewhat temperamental by his relatives, because of his attitude of non-acceptance of Jochi as Great Khan.  He was the most vocal about this issue among his relations.  Chaghatai himself appears to have been a just and energetic governor, though perhaps rough and uncouth, and addicted to hard drinking.  At any rate, he was animated by the soldier-like spirit of his father, and succeeded in keeping order among as heterogeneous a population as a kingdom was ever composed of. To Shoot an Elephant is a 2009 documentary film about the 2008-2009 Gaza War directed by Alberto Arce and Mohammad Rujailahk. Mongol ("Монгол" ), also known as Mongol: The Rise of Genghis Khan in the United States and Mongol: The Rise to Power of Genghis Khan in the United Kingdom, is a 2007 Russian semi-historical epic film directed by Sergei Bodrov, about the early life of Temüjin, who later came to be known as Genghis Khan.  The storyline was conceived from a screenplay written by Bodrov and Arif Aliev.  It was produced by Bodrov, Sergei Selyanov and Anton Melnik and stars Tadanobu Asano, Sun Honglei and Chuluuny Khulan in the main roles.  "Mongol" explores abduction, kinship and the repercussions of war. Belgutei was the son of Yesugei and half-brother to Genghis Khan.  He also became general to Genghis Khan.  Belgutei was considered a wise counselor and skilled diplomat, and was often used as a messenger by Genghis Khan.  With Genghis Khan's blessing, Belgutei killed the champion wrestler of the Mongols, Buri Boko, by breaking his neck during a wrestling match.  This was revenge for an earlier incident when Buri Boko had fought with Belgutei and slashed him with a sword.  According to legend, Belgutei lived to an unusually old age.  Rashid ad-Din claims he died at the age of 110, while the Yuanshi reports that he was still alive when Mongke Khan took the throne in 1251, making him around 100, which would make him one of the oldest men on the earth, a fact made even more difficult due to the average life span of people during the time. Descent from Genghis Khan (Mongolian: Алтан ураг Altan urag, meaning "Golden lineage"), generally called Genghisids, is traceable primarily in Mongolia, India, China, Russia, Southeast Asia and the Middle East.  His four sons and other immediate descendants are famous by names and by deeds.  Later Asian potentates attempted to claim descent from the Borjigin even on flimsy grounds, such as was considered Mongol matrilineal descent.  In the 14th century, valid sources (heavily dependent on Rashid-al-Din Hamadani and other Muslim historians) all but dried up.  With the recent popularity of genealogical DNA testing, a larger and broader circle of people started to claim descent from Genghis Khan.  It is estimated that 1 in 12.5 of the whole population of Asia and 1 in 200 of the whole population of the world is directly descended from Genghis Khan. Genghis Blues (1999) is a documentary film directed by Roko Belic.  It centers on the journey of blind American singer Paul Pena to the isolated Russian Republic of Tuva due to his interest in Tuvan throat singing. This is the timeline of the Mongol Empire from 1206, when Temüjin received the title of Genghis Khan, to the death in 1227 of the last successors to Genghis as overlord of all the Mongol dominions, though after the death of Kublai Khan in 1294, their suzerainty over the other divisions of the Mongol Empire (initially the Chagatai Khanate, the Golden Horde, and the Ilkhanate) was almost notional.  The Mongol Empire is usually considered to have come to an end in 1368, though the title of Khagan continued to be used by the rulers of the Northern Yuan dynasty, a far less powerful successor entity, until 1634.
