What was the cause of the fall of han dynasty? when?

 208 / 209, when his armies were defeated by the allied forces of Sun Quan and Liu Bei.

Corrupt officials and greedy aristocrats took over more of the land, forcing many farmers to give up their property. People began to rise up and rebel against the Han rulers. It ended in 220 AD. Hope this helps! :3
