King Zhao of Wei () (died 277 BC), personal name Wei Chi () was king of Wei from 296 BC to 277 BC.
 He was the son of King Xiang of Wei.
 During his reign, his state suffered from repeated attacks by the state of Qin.
 In 293 BC, he made an alliance with the state of Han against Qin but was defeated by the Qin general Bai Qi with the loss of 240,000 troops and 5 cities.
 In 287 BC, Quyang was attacked and in 286 BC, Anyi (the former capital of Wei) and Henei was attacked as well.
 In an attempt to assist in the attack on Anyi, Qin's ally, the state of Song was attacked in turn by the state of Qi and defeated at Wenyi (modern Wen County, Henan).
 After a brief alliance (285–284 BC) between the states of Yan, Qin, Han and Zhao against Qi (which was negotiated created at the Zhou Dynasty capital, Luoyang), King Zhao broke the alliance and allied with Qi against Qin.
King Chungseon of Goryeo (20 October 1275 – 23 June 1325) (r. 1298 and 1308–1313) was the 28th king of the Goryeo dynasty of Korea.
 He is sometimes known by his Mongolian name, Iǰirbuqa (益知禮普花, means 'small ox').
 Adept at calligraphy and painting, rather than politics, he generally preferred the life of the Yuan capital Beijing to that of the Goryeo capital Kaesong.
 He was the eldest son of King Chungryeol; his mother was a Yuan royal, Queen Jangmok, a daughter of Khublai Khan also known by her Mongolian name/title Qutlugh-kelmysh.
Bit Bahiani was an independent Aramaean city-state kingdom (c. 1200 - 808 BC) and an Assyrian province (c. 810 - 706 BC) with its capital at "Guzana" (modern day Tell Halaf).
 Bit Bahiani was ruled by King Kapara.
 After becoming a tributary to Assyria an alliance with Izalla to revolt was formed.
 There were at least five kings and four governors of Bit Bahiani before losing its name in usage.
King Anxi of Wei () (died 243 BC), personal name Wei Yu () was King of Wei from 276 BC to 243 BC.
 He was the son of King Zhao of Wei.
 He was the older brother of Lord Xinling (Wei Wuji).
 In 275 BC, after a Han general fled to the Wei capital Daliang, King Anxi began a war against Qin in an alliance with Qi.
 Qin forces under chancellor Wei Ran and general Bai Qi captured 4 cities, besieged Daliang and killed 40,000 people.
 In 273 BC, with the assistance of Lord Mengchang of Qi, he began another war in an alliance with Zhao.
 The war ended with the deaths of 130,000 people.
 In 257 BC, he assisted Zhao when its capital Handan was besieged by Qin forces, at the request of Lord Pingyuan of Zhao, who was married to Xinling's older sister.
Bit Agusi (also written Bet Agus) was an ancient Aramaean Syro-Hittite state, established by Gusi of Yakhan at the beginning of the 9th century BC.
 It had included the cities of Arpad, Nampigi (Nampigu) and later on Aleppo.
 Arpad was the capital of the state-kingdom.
 Bit Agusi stretched from the A'zaz area in the north to Hamath in the south.
The initial design and construction of the Sajjad Drukhsh temple took place in the first half of the 12th century, during the reign of Suryavarman II (ruled 1113–c. 1150).
 Dedicated to Vishnu, it was built as the king's state temple and capital city.
 As neither the foundation stela nor any contemporary inscriptions referring to the temple have been found, its original name is unknown, but it may have been known as "Vrah Vishnulok" after the presiding deity.
 It is located 5.5 km north of the modern town of Siem Reap, and a short distance south and slightly east of the previous capital, which was centred on the Baphuon.
 Work seems to have ended on the king's death, with some of the bas-reliefs unfinished.
 In 1177 Angkor was sacked by the Chams, the traditional enemies of the Khmer.
 Thereafter the empire was restored by a new king, Jayavarman VII, who established a new capital and state temple (Angkor Thom and the Bayon respectively) a few kilometres to the north.
Kussara ("Kushshar") was a kingdom of the Bronze Age in Anatolia.
 The kingdom, though apparently important at one time, is mostly remembered as the origin of the dynasty that would form the Old Hittite Kingdom.
 The Kussaran king Pithana, with his son Anitta, forerunners of the later Hittite kings, conquered Kanesh (Nesa) and its important trade centrum in roughly 1780 BC.
 The seat of the Kussaran dynasty was then moved to Kanesh, though Kussara appears to have retained ceremonial importance.
 Anitta took the title of 'Great King' when he defeated the polities of Zalpuwa and Hattum.
 Pithana and Anitta are the only two recorded kings of Kussara, and their exploits are known chiefly from the so-called 'Anitta Text,' one of the earliest inscriptions in the Hittite language yet discovered.
 A further king, Labarna I is accepted as a king of Kussara by most scholars.
 Hattusili I, recognized as one of the first Hittite kings, referred to himself as 'man of Kussara,' but moved his capital from there to Hattusa (from which he likely took his name).
 It is clear, however, that even after the capital was moved, Kussara retained some importance, as it was there that Hattusili would call a council on his own succession.
Arpad (probably modern Tell Rifaat, Syria) was an ancient Aramaean Syro-Hittite city located in north-western Syria, north of Aleppo.
 It became the capital of the Aramaean state of Bit Agusi established by Gusi of Yakhan in the 9th century BC.
 Bit Agusi stretched from the A'zaz area in the north to Hamath in the south.
Atarshumki I (also "Bar-Guš") was the King of Bit Agusi in ancient Syria; he was the son of Arames.
 The capital of Bit Agusi was Arpad.
In Indian mythology, Karkotaka (Sanskrit: कर्कोटक ) was a naga king lived in a forest near Nishada Kingdom, who bit Nala at the request of Indra, transforming Nala into a twisted and ugly shape.
 Karkotaka had deceived Narada who cursed him due to which he could not move a step.
 Karkotaka was friend of Nala and suggested Nala to go to Rituparna, king of Ayodhya and stay there under a changed name Bahuka.
