Pro aris et focis

Pro Aris et Focis is a Latin phrase used as the motto of many families, military regiments, and some educational institutions.

Meaning "For God and country" or literally "for our altars and our hearths", but is used by ancient authors to express attachment to all that was most dear and venerable. It could be more idiomatically translated "for hearth and home;" as the Latin term "aris", generally refers to either the altars of the spirits of the house and is often used as a synecdoche for the family home. Thus the famous Latin orator and philosopher Cicero uses the phrase to emphasize the importance of his argument in his philosophical work De Natura Deorum (3.40).
