For the Montenegrins of old, it was not their signature that was the ultimate moral bond, but their given word, (the word of honor). In his Honor and Heroism, Marko Miljanov Popovich, (1833—1901), the Duke of Montenegro, describes the events, depicting honor and heroism of his Montenegrin Serbs and other ethnicities: Albanians, Vlachs, and others. Marko Miljanov Popovich gives us the moral lecture: Honor—protecting others from yourself; heroism—protecting yourself from others.
