Eala Frya Fresena!  Lever Dod As Slaav!*

*Eala Freya Fresena (Hail [or Stand] Free Frisian) is the motto on the Ostfriesen coat-of-arms.  This greeting was used at the Upstalsboom near Rahe) in Medieval times when local chieftains met the first Tuesday after Pentecost.  The answer given was Lever Dood As Slav (better dead than slave).  The motto refers to the legendary "Frisian Freedom" the right of the Frisian to accept no rule besides the Holy Roman Emperor and the Christian God.

Moin is the greeting used in Ostfriesland.  Similar to "Have a Nice Day!"  Thought to have come from "Mojen Dach".
