Amr ibn al-As vs Sima Yi

Amr ibn al-As led the Muslim Arab army into Egypt, then a province of the Byzantine Empire. He defeated the Byzantines at the Battle of Heliopolis and captured the fortress of Babylon, leading to the surrender of Alexandria in 642.

Amr ibn al-As established the city of Fustat near the Nile Delta as the new capital of Muslim Egypt. The city became a major administrative and commercial center, later evolving into modern Cairo.

After the conquest, Amr ibn al-As was appointed governor of Egypt by Caliph Umar. He administered the province, implemented tax systems, and oversaw the construction of the Mosque of Amr ibn al-As, the first mosque in Africa.

Sima Yi led the Cao Wei forces to defeat the Shu Han army at Jieting, forcing Zhuge Liang to retreat. This victory prevented Shu from capturing the Chang'an region and secured Wei's western border.

Sima Yi successfully defended the city of Hefei against an Eastern Wu invasion led by Sun Quan. He repelled the Wu forces, maintaining Wei control over the Huai River region.

Sima Yi staged a coup against the regent Cao Shuang at the Gaoping Tombs. He seized control of the Cao Wei government, executing Cao Shuang and his faction. This event gave the Sima clan effective control over Wei.

Sima Yi died in 251 AD. His descendants later founded the Jin dynasty, fulfilling his ambition. He was posthumously honored as Emperor Xuan of Jin, though he never ruled as emperor himself.
