Context: The Mongols ("Mongolchuud") are an East-Central Asian ethnic group native to Mongolia and China's Inner Mongolia Autonomous Region. They also live as minorities in other regions of China (e.g. Xinjiang), as well as in Russia. Mongolian people belonging to the Buryat and Kalmyk subgroups live predominantly in the Russian federal subjects of Buryatia and Kalmykia., Indravarman V , Harideva , or Jaya Simhavarman , was a king of Champa whose reign began in 1257 when he assassinated his uncle Jaya Indravarman VI , but waited until 1266 for his coronation . Declining to submit himself in person to the Mongol Khan , Kublai Khan , he nevertheless `` subjected himself to this humiliation '' of the Mongol commanders Sagatou and Lieu Cheng dividing his kingdom into administrative units . His son , Ch Mân , `` could not resign himself . '' Sagatou launched an invasion in 1282 , forcing Indravarman V to flee to the mountains . Refusing to present himself in court and make an act of vassalage , he subjected the Mongols to suffer `` heat , illness , and a lack of supplies '' . Desertions amongst the Mongols also took their toll . Finally , after Sagatou 's death in 1285 , `` Champa found itself delivered of the Mongols . '' Indravarman V did send an ambassador to Kublai on 6 Oct. 1285 , and probably died soon afterwards ., Ch Mân, or Jaya Simhavarman III (r. 1288 - 1307), Prince Harijit, son of King Indravarman V and Queen Gaurendraksmi, was a king of Champa during a time when the threat of the Mongols was imminent. In 1282, Kublai Khan tried to gain passage through Champa of his ambassadors, but Ch Mân took them prisoner. Kublai Khan then asked Annam for entrance into Champa but received the same denial. In 1282, Kublai Khan invaded. Indravarman V and Crown Prince Harijit fled into the mountains, forcing the Mongols to suffer heat, illness, lack of supplies and desertion. The death of the top Mongol leader, Sagatou, was the beginning of the end of the Mongol invasion of Champa and Annam.
The mutual struggle against the Mongols brought Annam and Champa closer together. Thus, the Annamese king Tran Anh Tong married off his daughter, Huyen Tran, to Ch Mân in exchange for the provinces of O and Lý. His other "first rank wife", or "first queen", was Princess Bhaskaradevi, though he also married a princess from Java, Queen Tapasi., Cambodia (or Kampuchea ), officially known as the Kingdom of Cambodia (Preh Réachéanachâk Kâmpchéa), is a country located in the southern portion of the Indochina Peninsula in Southeast Asia. It is in area, bordered by Thailand to the northwest, Laos to the northeast, Vietnam to the east, and the Gulf of Thailand to the southwest., Temple names are commonly used when naming most Chinese, Korean (Goryeo and Joseon periods), and Vietnamese (such dynasties as Trn, Lý, and Lê) royalty. They should not be confused with era names. Compared to posthumous names, the use of temple names is more exclusive. Both titles were given after death to an emperor or king, but unlike the often elaborate posthumous name, a temple name almost always consists of only two characters:, The term Champa refers to a collection of independent Cham polities that extended across the coast of what is today central and southern Vietnam from approximately the 2nd century through 19th century (1832), before being absorbed and annexed by the Vietnamese state. The kingdom was known variously as "nagara Campa" (Sanskrit:  ) in the Chamic and Cambodian inscriptions, in Vietnamese ("Chiêm Thành" in Sino-Vietnamese vocabulary) and (Zhànchéng) in Chinese records., Vietnam, officially the Socialist Republic of Vietnam (SRV), is the easternmost country on the Indochina Peninsula in Southeast Asia. With an estimated 90.5 million inhabitants , it is the world's 14th-most-populous country, and the eighth-most-populous Asian country. Vietnam is bordered by China to the north, Laos to the northwest, Cambodia to the southwest, Thailand across the Gulf of Thailand to the southwest, and the Philippines, Malaysia and Indonesia across the South China Sea to the east and southeast. Its capital city has been Hanoi since the reunification of North and South Vietnam in 1976., Sanskrit (English pronunciation:; written in Devanagari script ; : or ', originally ', "refined speech") is the primary sacred language of Hinduism and "Mahyna" Buddhism, a philosophical language in Hinduism, Jainism, Buddhism and Sikhism. It was also a literary language that was in use as a "lingua franca" in ancient and medieval South Asia. It is a standardised dialect of Old Indo-Aryan, originating as Vedic Sanskrit and tracing its linguistic ancestry back to Proto-Indo-Iranian and Proto-Indo-European. Today it is listed as one of the 22 scheduled languages of India and is an official language of the state of Uttarakhand. As one of the oldest Indo-European languages for which substantial written documentation exists, Sanskrit holds a prominent position in Indo-European studies., A conquest dynasty in the history of imperial China refers to a dynasty established by non-Han peoples that ruled parts or all of the China proper, such as the Mongol Yuan dynasty and the Manchu Qing dynasty., Kublai Khan ("Xubila xaan" "Khagan Qubilai"; September 23, 1215  February 18, 1294), born Kublai ("Xubila" also spelled Khubilai) and also known by the temple name Shizu (Emperor Shizu of Yuan), was the fifth Khagan (Great Khan) of the Mongol Empire ("Ikh Mongol Uls"), reigning from 1260 to 1294 (although due to the division of the empire this was a nominal position). He also founded the Yuan dynasty in China as a conquest dynasty in 1271, and ruled as the first Yuan emperor until his death in 1294., China, officially the People's Republic of China (PRC), is a unitary sovereign state in East Asia. With a population of over 1.381 billion, it is the world's most populous country. The state is governed by the Communist Party of China, and its capital is Beijing. It exercises jurisdiction over 22 provinces, five autonomous regions, four direct-controlled municipalities (Beijing, Tianjin, Shanghai, and Chongqing), and two mostly self-governing special administrative regions (Hong Kong and Macau), and claims sovereignty over Taiwan. The country's major urban areas include Shanghai, Guangzhou, Beijing, Chongqing, Shenzhen, Tianjin and Hong Kong. China is a great power and a major regional power within Asia, and has been characterized as a potential superpower., The Yuan dynasty, officially the Great Yuan, was the empire or ruling dynasty of China established by Kublai Khan, leader of the Mongolian Borjigin clan. Although the Mongols had ruled territories including today's North China for decades, it was not until 1271 that Kublai Khan officially proclaimed the dynasty in the traditional Chinese style, and the conquest was not complete until 1279. His realm was, by this point, isolated from the other khanates and controlled most of present-day China and its surrounding areas, including modern Mongolia. It was the first foreign dynasty to rule all of China and lasted until 1368, after which its Genghisid rulers returned to their Mongolian homeland and continued to rule the Northern Yuan dynasty. Some of the Mongolian Emperors of the Yuan mastered the Chinese language, while others only used their native language (i.e. Mongolian) and the 'Phags-pa script., The Mongol Empire (Mongolian: "Mongolyn Ezent Güren" ; Mongolian Cyrillic:    also ("Horde") in Russian chronicles) existed during the 13th and 14th centuries and was the largest contiguous land empire in history. Originating in the steppes of Central Asia, the Mongol Empire eventually stretched from Central Europe to the Sea of Japan, extending northwards into Siberia, eastwards and southwards into the Indian subcontinent, Indochina, and the Iranian plateau, and westwards as far as the Levant and Arabia., Subject: indravarman v, Relation: country_of_citizenship, Options: (A) annam (B) cambodia (C) china (D) goryeo (E) india (F) japan (G) mongol empire (H) mongolia (I) qing dynasty (J) realm (K) republic of china (L) russia (M) thailand (N) vietnam (O) yuan dynasty
