This is my family coats-of-arms. I've always found it interesting. "Pro libertate" means "For liberty," which only comes from having a shield (on which the coat-of-arms was imprinted) and a sword to defend yourself, and a lion (called a rampant lion) with it's claws out, ready to strike.
To keep your liberty you must always be on guard, and have the ability to strike and defend.
