Hey,

I have read some history manga like Akagami no shirayukihime and Soredemo sekaii wa utsukii.
And I am looking for another one like that one, one with love in it and a noble or prince or princess in it.

Has anyone an good manga for me¿

Ships but the romance isn't the "main" story
Song of the Long March
The Moon that rises in the day
Suijin no Ikenie

Not up to date on these but it has good reception:
Joou no Hana
The Story of Saiunkoku
Koukyuu Days - Shichi Kuni Monogatari

seconding Song of the Long March, Suijin no ikenie and joou no hana

adding Yeonmo and Pellua Iyagi

Reimei no Arcana might be of interest to you. MC and love interest are both royalty.

Seconding (or thirding?) Song of the Long March. It's an actual historical and not historical fantasy like the rest of these.
