I only just discovered that there are clubs on MDL, and I really like it here - your wide definition of historical suits me :) I am therefore taking the liberty to join you, even though I may not turn out to be much of a contributor (too busy to watch many dramas TT ). Also, I don't usually watch dramas while they're airing. I can't bear the wait for new episodes, I want to watch in my own time.
I mostly watch wuxia these days, but I also like xianxia (I don't know the names of all subgenres, so maybe I should say Chinese fantasy in general?). My first historical drama, however, was Love in the Moonlight, and I have a soft spot for Sungkyunkwan Scandal.
And... let me just say I'm becoming a professional escapist :D I mostly like dramas because they inspire my mind - and in my mind, if not in real life, I can be as powerful as I like.
