Can a 皇帝 be female?


What would the word for empress (other than of Japan) be? Please give me the
word for a ruling empress.




It's [[女帝]{じょてい}](http://ja.wikipedia.org/wiki/%E5%A5%B3%E5%B8%9D).

皇帝 is also used for an empress, e.g.:
[アンナ(ロシア皇帝)](http://ja.wikipedia.org/wiki/%E3%82%A2%E3%83%B3%E3%83%8A_%28%E3%83%AD%E3%82%B7%E3%82%A2%E7%9A%87%E5%B8%9D%29)
