Abu Bakr vs Dorgon

Abu Bakr launched military campaigns against Arabian tribes that renounced Islam or refused to pay zakat after Muhammad's death. The wars, led by generals like Khalid ibn al-Walid, reestablished Muslim control over Arabia and consolidated the caliphate.

After the death of Muhammad, Abu Bakr was elected as the first caliph (successor) at Saqifah. His election unified the Muslim community, though it caused controversy among some supporters of Ali. He became the leader of the nascent Islamic state.

Abu Bakr ordered the compilation of the Quran into a single written manuscript after many memorizers died in the Ridda Wars. Zayd ibn Thabit collected verses from various sources, creating the first official codex, which later served as the basis for Uthman's standard text.

Abu Bakr died after a brief illness, having designated Umar as his successor. His caliphate lasted only two years but established the foundations of the Islamic state, including the expansion beyond Arabia and the preservation of the Quran.

Upon the death of Hong Taiji, Dorgon was appointed as regent for the young Shunzhi Emperor. This position gave him effective control over the Qing government and military, enabling him to direct the conquest of Ming China.

Dorgon allied with Ming general Wu Sangui to defeat Li Zicheng's rebel forces at Shanhai Pass. This victory allowed Qing forces to enter Beijing and establish the Qing dynasty as the ruling power in China.

Dorgon led Qing forces in a campaign against the Southern Ming regime, capturing Nanjing and defeating the Hongguang Emperor. This campaign extended Qing control over the Yangtze River valley and weakened Ming loyalist resistance.

Dorgon mandated that all Chinese men adopt the Manchu queue hairstyle as a sign of submission to Qing rule. This policy caused widespread resentment and resistance, but was enforced to consolidate Qing control over Han Chinese subjects.

Dorgon died suddenly while hunting. After his death, the Shunzhi Emperor accused him of plotting to usurp the throne, stripped him of all titles, and had his corpse mutilated. This posthumous purge reflected court factional struggles.
