Unus pro omnibus, omnes pro uno
Unus pro omnibus, omnes pro uno is a Latin phrase that means One for all, all for one. It is the unofficial motto of Switzerland, and the attitude is epitomized in the character of legendary Swiss hero Arnold von Winkelried. A French version, Un pour tous, tous pour un, was made famous by Alexandre Dumas in the 1844 novel The Three Musketeers.
