Yep, Empire is Reinassence, last quarter of XV and XVI century. Bretonnian is XIII - XIV century. Araby is also Reinassence XV XVI ottoman turks and Kislev, I guess, is also reinassence XVI-XVII polish-russian (Eissenstein Ivan the terrible film is a great example of kislev).
In my humble opinion those figueres are cool for backwards provinces of empire or bretonians.
