But i do know that the Arabs hated the rule of the Umayyads for most of their leaders except one for example.
Doesn't tell much other than that the ruling dynasty is terrible at its job.
This can be seen even outside of empires where the new ruling entity changes the social structures and institutions drastically.
Not an argument.
Explain why when they were under the Ming dynasty they were different nations and not part of one nation.
And why didn't they rise up against it before the economic conditions went south.
I am aware of the revolutions that took place in the 20th century.
If it was as different as you make it seem then their rule wont last nearly 300 years.
And the only problems it seemed to have is mainly external by Europeans majorly not internal.
Here, the same reason as before during the Ming rule:
The Taiping Rebellion in the mid-19th century was the first major instance of anti-Manchu sentiment. Amid widespread social unrest and worsening famine, the rebellion not only posed the most serious threat towards Qing rulers, it has also been called the "bloodiest civil war of all time"; during its fourteen-year course from 1850 to 1864 between 20 and 30 million people died. Hong Xiuquan, a failed civil service candidate, in 1851 launched an uprising in Guizhou province, and established the Taiping Heavenly Kingdom with Hong himself as king. Hong announced that he had visions of God and that he was the brother of Jesus Christ. Slavery, concubinage, arranged marriage, opium smoking, footbinding, judicial torture, and the worship of idols were all banned. However, success led to internal feuds, defections and corruption. In addition, British and French troops, equipped with modern weapons, had come to the assistance of the Qing imperial army. It was not until 1864 that Qing armies under Zeng Guofan succeeded in crushing the revolt. After the outbreak of this rebellion, there were also revolts by the Muslims and Miao people of China against the Qing dynasty, most notably in the Miao Rebellion (1854–73) in Guizhou, the Panthay Rebellion (1856–1873) in Yunnan and the Dungan Revolt (1862–77) in the northwest.https://en.wikipedia.org/wiki/Qing_dyna ... l_pressure
Same reasons, bad conditions led to uprisings.
In the Ming dynasty, poor conditions and poverty along with bad governance also led to uprisings which led to their fall.
