I love all historical k-drama in general but those, I looked several times and never get tired of watching yet : - DAMO - Queen Seon-Duk - FAITH - Dae Jang Geum -Ja Myung Go -Jejoongwon - Sungkyunkwan Scandal - Iljimae
Princess' Man Iljimae Bridal Mask The Moon that Embraces the Sun Arang and the Magistrate
I love historical dramas, but I still need to watch all the longer period dramas like Jumong and Queen Seon Duk.

Drama:

- Gumiho: Tale of the Fox's Child
- Tamra, The Island
- The Princess' Man
- Iljimae

Movie:

- Masquerade
I still need to watch "Iljimae". I've been meaning to watch it for SO LONG. For me my favorite historical-ish dramas so far were: 1 - The Legend 2 - The Princess' Man 3 - Queen Seon-duk 4 - Tree with Deep Roots I'm not counting "Queen In Hyun's Man" because... let's face it... no one watched it for the History lesson.
Kdrama :
Bridal Mask
The Princess Man
Sungkyunkwan Scandal
Gu Family Book
Chuno

Kmovie :
Taegukgi
