The Quran and Muhammad talked about racial equality and justice as in The Farewell Sermon. Tribal and nationalistic differences were discouraged. But after Muhammad's passing, the old tribal differences between the Arabs started to resurface. Following the Roman–Persian Wars and the Byzantine–Sassanid Wars, deep rooted differences between Iraq, formally under the Persian Sassanid Empire, and Syria, formally under the Byzantine Empire, also existed. Each wanted the capital of the newly established Islamic State to be in their area. Previously, the second caliph Umar was very firm on the governors and his spies kept an eye on them. If he felt that a governor or a commander was becoming attracted to wealth, he had him removed from his position.
Who was the second caliph?
Umar


Input: Sino-Tibetan relations during the Ming dynasty
Some scholars note that Tibetan leaders during the Ming frequently engaged in civil war and conducted their own foreign diplomacy with neighboring states such as Nepal. Some scholars underscore the commercial aspect of the Ming-Tibetan relationship, noting the Ming dynasty's shortage of horses for warfare and thus the importance of the horse trade with Tibet. Others argue that the significant religious nature of the relationship of the Ming court with Tibetan lamas is underrepresented in modern scholarship. In hopes of reviving the unique relationship of the earlier Mongol leader Kublai Khan (r. 1260–1294) and his spiritual superior Drogön Chögyal Phagpa (1235–1280) of the Sakya school of Tibetan Buddhism, the Yongle Emperor (r. 1402–1424) made a concerted effort to build a secular and religious alliance with Deshin Shekpa (1384–1415), the Karmapa of the Karma Kagyu school. However, the Yongle Emperor's attempts were unsuccessful.

Who did the Yongle Emperor try to build a religious alliance with?
Output: Deshin Shekpa


Input: Article: Though many of the events were outside the traditional time-period of the Middle Ages, the end of the unity of the Western Church (the Protestant Reformation), was one of the distinguishing characteristics of the medieval period. The Catholic Church had long fought against heretic movements, but during the Late Middle Ages, it started to experience demands for reform from within. The first of these came from Oxford professor John Wycliffe in England. Wycliffe held that the Bible should be the only authority in religious questions, and he spoke out against transubstantiation, celibacy and indulgences. In spite of influential supporters among the English aristocracy, such as John of Gaunt, the movement was not allowed to survive. Though Wycliffe himself was left unmolested, his supporters, the Lollards, were eventually suppressed in England.

Now answer this question: What was the event that ended religious unity in the Western Church?

Output: the Protestant Reformation


Article: Unfortunately, Isabella was already engaged to Hugh of Lusignan, an important member of a key Poitou noble family and brother of Count Raoul of Eu, who possessed lands along the sensitive eastern Normandy border. Just as John stood to benefit strategically from marrying Isabella, so the marriage threatened the interests of the Lusignans, whose own lands currently provided the key route for royal goods and troops across Aquitaine. Rather than negotiating some form of compensation, John treated Hugh "with contempt"; this resulted in a Lusignan uprising that was promptly crushed by John, who also intervened to suppress Raoul in Normandy.

Question: Hugh of Lusignan was an important member of what?
Ans: a key Poitou noble family


Here is a question about this article: The capital of Danish Estonia (Danish: Hertugdømmet Estland) was Reval (Tallinn), founded at the place of Lyndanisse after the invasion of 1219. The Danes built the fortress of Castrum Danorum at Toompea Hill. Estonians still call their capital "Tallinn", which according to legend derives from Taani linna (meaning Danish town or castle). Reval was granted Lübeck city rights (1248) and joined the Hanseatic League. Even today, Danish influence can be seen in heraldic symbols. The Danish cross is on the city of Tallinn's coat of arms, and Estonia's coat of arms displays three lions similar to those found on the Danish coat of arms.
What is the answer to this question: What was the capital of Danish Estonia?
****
So... Reval


Article: Beginning in the late 1910s and early 1920s, Whitehead gradually turned his attention from mathematics to philosophy of science, and finally to metaphysics. He developed a comprehensive metaphysical system which radically departed from most of western philosophy. Whitehead argued that reality consists of processes rather than material objects, and that processes are best defined by their relations with other processes, thus rejecting the theory that reality is fundamentally constructed by bits of matter that exist independently of one another. Today Whitehead's philosophical works – particularly Process and Reality – are regarded as the foundational texts of process philosophy.

Question: After moving away from mathematics, what subjects did Whitehead explore?
Ans:
philosophy of science, and finally to metaphysics
