Leonidas was a former King of the warrior nation of Sparta. Even if you are not a history buff, you have probably heard of the movie The 300 where Leonidas and his men fought to the last man. The Spartans lead a very severe lifestyle in order to become great warriors. Weak or infirm babies were abandoned to die as they were felt to be inferior and not valued by the society. Spartan culture was all about the good of the society and men were taught to either return victorious (with their shields) or dead (upon their shields).
