Umar
ʿUmar ibn al-Khaṭṭāb ( ar, عمر بن الخطاب, also spelled Omar, ) was the second Rashidun caliph, ruling from August 634 until his assassination in 644. He succeeded Abu Bakr () as the second caliph of the Rashidun Caliphate on 23 August 634. Umar was a senior companion and father-in-law of the Islamic prophet Muhammad. He was also an expert Muslim jurist known for his pious and just nature, which earned him the epithet ''al-Fārūq'' ("the one who distinguishes (between right and wrong)"). Umar initially opposed Muhammad, his distant Qurayshite kinsman and later son-in-law. Following his conversion to Islam in 616, he became the first Muslim to openly pray at the Kaaba. Umar participated in almost all battles and expeditions under Muhammad, who bestowed the title ''al-Fārūq'' ('the Distinguisher') upon Umar, for his judgements. After Muhammad's death in June 632, Umar pledged allegiance to Abu Bakr () as the first caliph and served as the closest adviser t ...

Tang Dynasty
The Tang dynasty (, ; zh, t= ), or Tang Empire, was an Dynasties in Chinese history, imperial dynasty of China that ruled from 618 to 907 AD, with an Zhou dynasty (690–705), interregnum between 690 and 705. It was preceded by the Sui dynasty and followed by the Five Dynasties and Ten Kingdoms period. Historians generally regard the Tang as a high point in Chinese civilization, and a Golden age (metaphor), golden age of cosmopolitan culture. Tang territory, acquired through the military campaigns of its early rulers, rivaled that of the Han dynasty. The House of Li, Lǐ family () founded the dynasty, seizing power during the decline and collapse of the Sui Empire and inaugurating a period of progress and stability in the first half of the dynasty's rule. The dynasty was formally interrupted during 690–705 when Empress Wu Zetian seized the throne, proclaiming the Zhou dynasty (690–705), Wu Zhou dynasty and becoming the only legitimate Chinese empress regnant. The devast ...

Abu Lu'lu'a Firuz
Abū Luʾluʾa Fīrūz ( ar, أبو لؤلؤة فيروز; from ), also known as Bābā Shujāʿ al-Dīn ( ar, بابا شجاع الدين, label=none), was a Sassanid Persian slave known for having assassinated Umar ibn al-Khattab (), the second Islamic caliph, in November 644. After having been captured in battle during the Arab-Muslim conquest of Persia, Abu Lu'lu'a was brought to Medina, the then-capital of the Rashidun Caliphate, which was normally off-limits to non-Arab captives. However, as a highly skilled craftsman, Abu Lu'lu'a was exceptionally allowed entrance into the city in order to work for the caliph. His motive for killing the caliph is not entirely clear, but medieval sources generally attribute it to a tax dispute. At one point, Abu Lu'lu'a is said to have asked the caliph to lift a tax imposed upon him by his Arab master, al-Mughira ibn Shu'ba. When Umar refused to lift the tax, Abu Lu'lu'a attacked him while he was leading the congregational prayer in the ...

Tang Campaigns Against Karasahr
The Tang campaigns against Karasahr () were two military campaigns sent by Emperor Taizong of the Tang dynasty against the Tarim Basin kingdom of Karasahr, a vassal of the Western Turkic Khaganate. The city-state, which later became part of Xinjiang), may have been known to its inhabitants by the Tocharian name ''Agni'', which was rendered ''Yanqi'' in Chinese sources. The first campaign in 644 was led by the Tang commander Guo Xiaoke, protector-general of the Anxi Protectorate in western China, who defeated the oasis state and a Western Turkic army and installed a Tang loyalist as ruler. The second campaign in 648, which was part of the campaign against Karasahr's neighboring state of Kucha, was led by a Turkic general of the Tang Dynasty, Ashina She'er, who defeated and conquered Karasahr. Background Karasahr, a kingdom in the Tarim Basin, became a tributary state of Tang China in 632. In 632, the nearby oasis states Kashgar and Khotan surrendered to Chinese suzerainty, as ...

Emperor Taizong Of Tang
Emperor Taizong of Tang (28January 59810July 649), previously Prince of Qin, personal name Li Shimin, was the second emperor of the Tang dynasty of China, ruling from 626 to 649. He is traditionally regarded as a co-founder of the dynasty for his role in encouraging Li Yuan, his father, to rebel against the Sui dynasty at Jinyang in 617. Taizong subsequently played a pivotal role in defeating several of the dynasty's most dangerous opponents and solidifying its rule over China. Taizong is considered to be one of the greatest emperors in China's history and henceforth, his reign became regarded as the exemplary model against which all future emperors were measured. His era, the "Reign of Zhenguan ()" is considered a golden age in ancient Chinese history and was treated as required studying material for future crown princes. Taizong continued to develop imperial examination systems. He asked his officers to become loyal to the policies not people, in order to eliminate corru ...

Valentinus (usurper)
Valentinus ( gr, Οὐαλεντῖνος/Βαλεντῖνος) (died 644) was a Byzantine general and usurper. Biography According to Sebeos, Valentinus was of Armenian origin, being descended from the royal Arsacid clan... He was initially a member of the retinue of the ''sakellarios'' Philagrius, and was tasked in early 641 by Emperor Constantine III (r. February–May 641) to distribute money to the troops in order to secure their loyalty to his infant son Constans, and not the faction of Heraclius's empress-dowager Martina. It is possible that he had been appointed as general or plenipotentiary over the Byzantine army, or that he held the post of '' comes Obsequii''. In the event, however, on Emperor Constantine's death in May 641, Martina and her son Heraklonas seized power, whilst the loyalists of Constans, most prominently Philagrius, were banished. At this point, Valentinus, who had carried out his assignment and secured the support of the army, led the troops to Chalced ...

Oswiu Of Northumbria
Oswiu, also known as Oswy or Oswig ( ang, Ōswīg; c. 612 – 15 February 670), was King of Bernicia from 642 and of Northumbria from 654 until his death. He is notable for his role at the Synod of Whitby in 664, which ultimately brought the church in Northumbria into conformity with the wider Catholic Church. One of the sons of Æthelfrith of Bernicia, Oswiu became king following the death of his brother Oswald in 642. Unlike Oswald, Oswiu struggled to exert authority over Deira, the other constituent kingdom of medieval Northumbria, for much of his reign. Oswiu and his brothers were raised in exile in the Irish kingdom of Dál Riata in present-day Scotland after their father's death at the hands of Edwin of Deira, only returning after Edwin's death in 633. Oswiu rose to the kingship when his brother Oswald was killed in battle against Penda of Mercia. The early part of his reign was defined by struggles to assert control over Deira and his contentious relationship with Penda, h ...

Constans II
Constans II ( grc-gre, Κώνστας, Kōnstas; 7 November 630 – 15 July 668), nicknamed "the Bearded" ( la, Pogonatus; grc-gre, ὁ Πωγωνᾶτος, ho Pōgōnãtos), was the Eastern Roman emperor from 641 to 668. Constans was the last attested emperor to serve as consul, in 642, although the office continued to exist until the reign of Leo VI the Wise (r. 886–912). His religious policy saw him steering a middle line in disputes between the Orthodoxy and Monothelitism by refusing to persecute either and prohibited discussion of the natures of Jesus Christ under the Type of Constans in 648. His reign coincided with Muslim invasions under Mu'awiya I in the late 640s to 650s. Constans was the first Roman emperor to visit Rome since the fall of the Western Roman Empire in 476, and the last emperor to visit Rome while it was still held by the Empire. Origins and early career Constans was born on 7 November 630 in Constantinople, the East-Roman capital. His father Constan ...

Oswine Of Deira
Oswine, Oswin or Osuine (died 20 August 651) was a King of Deira in northern England. Life Oswine succeeded King Oswald of Northumbria, probably around the year 644, after Oswald's death at the Battle of Maserfield. Oswine was the son of Osric. His succession, perhaps the choice of the people of Deira, split the Kingdom of Northumbria. Oswiu was the successor of Bernicia to the north. After seven years of peaceful rule, Oswiu declared war on Oswine. Oswine refused to engage in battle, instead retreating to Gilling and the home of his friend, Earl Humwald. Humwald betrayed Oswine, delivering him to Oswiu's soldiers by whom Oswine was put to death, probably at Diddersley Hill in North Yorkshire. Veneration In Anglo-Saxon culture, it was assumed that the nearest kinsmen to a murdered person would seek to avenge the death or require some other kind of justice on account of it (such as the payment of wergild: a sum of money paid to the relatives of a slain man on account of the k ...

Deira
Deira ( ; Old Welsh/Cumbric: ''Deywr'' or ''Deifr''; ang, Derenrice or ) was an area of Post-Roman Britain, and a later Anglian kingdom. Etymology The name of the kingdom is of Brythonic origin, and is derived from the Proto-Celtic *''daru'', meaning 'oak' ( in modern Welsh), in which case it would mean 'the people of the Derwent', a derivation also found in the Latin name for Malton, . It is cognate with the modern Irish word (); the names for County Londonderry and the city of Derry stem from this word. History Brythonic Deira Following the Roman withdrawal from Britain a number of successor kingdoms rose in northern England, reflecting pre-Roman tribal territories. The area between the Humber and River Tees known as ''Deywr'' or ''Deifr'' corresponds to the tribal lands of the Parisi, bordered to the west and north by the Brythonic kingdoms of '' Elfed'' and '' Bryneich'' respectively, and to the east by the North Sea. Early Deira may have centred on Petuaria (moder ...
