Ali ibn Abi Talib vs Yuri Dolgorukiy

Ali defeated a coalition led by Aisha, Talha, and Zubayr near Basra. The battle, named after Aisha's camel, was the first major conflict between Muslims. It resulted in the deaths of many prominent Companions and deepened the rift in the community.

Ali ibn Abi Talib became the fourth caliph after Uthman's assassination. His reign was marked by internal conflicts, including the Battle of the Camel and the Battle of Siffin, as he struggled to assert authority over a divided Muslim community.

Ali's forces fought Muawiyah's army at Siffin in Syria. The battle ended in a stalemate when Muawiyah's troops raised copies of the Quran, calling for arbitration. Ali agreed, leading to a split among his supporters and the emergence of the Kharijites.

The arbitration between Ali and Muawiyah at Adhruh resulted in a decision that undermined Ali's claim to the caliphate. The outcome alienated many of Ali's supporters, leading to the Kharijite rebellion and weakening his position.

Ali was assassinated by a Kharijite named Ibn Muljam while praying at the mosque in Kufa. His death ended the Rashidun Caliphate and led to the establishment of the Umayyad dynasty under Muawiyah, cementing the Sunni-Shia split.

Yuri Dolgorukiy invited Prince Sviatoslav Olgovich to a meeting at a place called 'Moscow' in the chronicles. This first written mention of Moscow is traditionally considered the founding date of the city.

Yuri Dolgorukiy launched a campaign to seize the throne of Kiev from his nephew Iziaslav. He captured Kiev in 1149 and ruled briefly, but was expelled in 1151. He finally secured Kiev in 1155, ruling until his death.

Yuri Dolgorukiy ordered the construction of a wooden fortress (kremlin) on Borovitsky Hill in Moscow. This fortification became the nucleus of the future Moscow Kremlin and the city's defensive core.

Yuri Dolgorukiy died suddenly after a feast in Kiev, suspected of being poisoned by the Kievan boyars. His death ended his rule and led to a revolt against his administration in Kiev.
