Err no. Her illegal seizure of power caused multiple rebellions. Externally, the Turks completely broke away and armies sent to subdue the empire’s enemies met major reverses due to Wu Zetian being only willing to entrust the army to her nephews. The main reason why she wasn’t condemned had to do with the fact that all the subsequent Tang emperors were her descendants.
Wu Zetian's character and achievements have been debated by historians over the centuries. Some viewed her as a ruthless and power-hungry leader who used any means necessary to gain and maintain her position of authority. Others saw her as a capable and intelligent ruler who brought stability, prosperity, and cultural advancements to China during her reign.
During her rule, Wu Zetian implemented a series of reforms that benefited the country, including expanding the education system, promoting Buddhism, and improving the civil service. She also oversaw the construction of several public works, including a new canal that facilitated trade and transportation.
Overall, Wu Zetian's legacy is mixed, with some historians viewing her as a talented ruler who made significant contributions to China's development, while others see her as a power-hungry and ruthless tyrant who was lucky enough to be at the right place at the right time.
You can't really paint her in one color.
