Uthman ibn Affan was the third caliph, ruling from 644 until his assassination in 656.

During his reign as caliph, he was known for ordering the official compilation of the standardized version of the Quran that is still being used today.
Sigebert III was the Merovingian king of Austrasia from 633 to his death around 656. He was described as the first Merovingian roi fainéant —do-nothing king—, in effect the mayor of the palace ruling the kingdom throughout his reign. However he lived a pious Christian life and was later sanctified, being remembered as Saint Sigebert of Austrasia in the Roman Catholic Church and Eastern Orthodox Church.
The Battle of the Camel took place outside of Basra, Iraq, in 36 AH. The battle was fought between the army of the fourth caliph Ali, on one side, and the rebel army led by Aisha, Talha and Zubayr, on the other side. Ali was the cousin and son-in-law of the Islamic prophet Muhammad, while Aisha was a widow of Muhammad, of whom Talha and Zubayr were both prominent companions. Ali emerged victorious from the battle, Talha and Zubayr were both killed, and Aisha was sent back to Hejaz afterward. The triumvirate had revolted against Ali ostensibly to avenge the assassination of the third caliph Uthman, although Aisha and Talha are both known to have actively opposed him. The three also called for the removal of Ali from office and for a Qurayshite council (shura) with Talha and Zubayr to appoint his successor.
Abu Uthman Amr ibn Uthman ibn Affan al-Umawi was a son of Caliph Uthman and played political and military roles during the caliphates of Mu'awiya I, Yazid I and Marwan I.
