Exactly; she is a despised figure. It would be like choosing James Buchanan or Warren Harding to be the leader for the USA (if they happened to be women

).
Most of the women in Civ V/G&K deserve to be there;
Wu does not, nor does Dido, who is like Gilgamesh in Civ IV, more mythical than historical.
Why not Hannibal? It's not like Gandhi ever ruled India.
How many times do I have to tell people who know barely something about Chinese history,let alone Empress Wu Zetian!?
She was a great person an totally worthy to be in this game.
She was the first great empress of China.
She reconquered some territories that Taizong conquered and were lost.
She provided better equality.
She was great at administration,she appointed people by looking at their talents and not by social status.
She built many temples and pagodas.
She was fair to the lower classes and lowered taxes.
She reduced the size of the army,which saved lots of money.
She did a lot of great things,but she was cruel,yes,but those who want to achieve greatness must sometimes do cruel things.
She was incorrupt,intelligent,ambitious and prescient
She improved agriculture and placed a lot of importance it.
The empire prospered and there was peace.
She managed to hold the empire unified and stop rebellions(if there were any),while much emperors destroyed themselves and China
She helped spreading Buddhism
I watched a movie about her and she said:
For those who want to achieve greatness,everything is expendable
Which states (at least in the film) that she provided a quote for history,while almost none of the Chinese emperors have one.
And if you think she is cruel,there a lot (Chinese) leaders that are more cruel then her(Qin Shi Huang)
The point is that she was a great person and deserves it to be in the game
Well,she's is probably not the greatest leader in Chinese history,but she is one the greatest and remarkable.
