The white flag is an internationally recognized protective sign of truce or ceasefire, and for negotiation. It is also used to symbolize surrender, since it is often the weaker party that requests negotiation. It is also flown on ships serving as cartels. A white flag signifies to all that an approaching negotiator is unarmed, with an intent to surrender or a desire to communicate. Persons carrying or waving a white flag are not to be fired upon, nor are they allowed to open fire. The use of the flag to request parley is included in the Hague Conventions of 1899 and 1907:[1]
