Input: Article: Armenian literature dates back to 400 AD, when Mesrop Mashtots first invented the Armenian alphabet. This period of time is often viewed as the Golden Age of Armenian literature. Early Armenian literature was written by the "father of Armenian history", Moses of Chorene, who authored The History of Armenia. The book covers the time-frame from the formation of the Armenian people to the fifth century AD. The nineteenth century beheld a great literary movement that was to give rise to modern Armenian literature. This period of time, during which Armenian culture flourished, is known as the Revival period (Zartonki sherchan). The Revivalist authors of Constantinople and Tiflis, almost identical to the Romanticists of Europe, were interested in encouraging Armenian nationalism. Most of them adopted the newly created Eastern or Western variants of the Armenian language depending on the targeted audience, and preferred them over classical Armenian (grabar). This period ended after the Hamidian massacres, when Armenians experienced turbulent times. As Armenian history of the 1920s and of the Genocide came to be more openly discussed, writers like Paruyr Sevak, Gevork Emin, Silva Kaputikyan and Hovhannes Shiraz began a new era of literature.

Input: Article: While the Umayyads and the Hashimites may have had bitterness between the two clans before Muhammad, the rivalry turned into a severe case of tribal animosity after the Battle of Badr. The battle saw three top leaders of the Umayyad clan (Utba ibn Rabi'ah, Walid ibn Utbah and Shaybah) killed by Hashimites (Ali, Hamza ibn 'Abd al-Muttalib and Ubaydah ibn al-Harith) in a three-on-three melee. This fueled the opposition of Abu Sufyan ibn Harb, the grandson of Umayya, to Muhammad and to Islam. Abu Sufyan sought to exterminate the adherents of the new religion by waging another battle with Muslims based in Medina only a year after the Battle of Badr. He did this to avenge the defeat at Badr. The Battle of Uhud is generally believed by scholars to be the first defeat for the Muslims, as they had incurred greater losses than the Meccans. After the battle, Abu Sufyan's wife Hind, who was also the daughter of Utba ibn Rabi'ah, is reported to have cut open the corpse of Hamza, taking out his liver which she then attempted to eat. Within five years after his defeat in the Battle of Uhud, however, Muhammad took control of Mecca and announced a general amnesty for all. Abu Sufyan and his wife Hind embraced Islam on the eve of the conquest of Mecca, as did their son (the future caliph Muawiyah I).
