Giannias was born in Prostovitsa , a village now known as Drosia in Achaia . He was the brother of Giannis Giannias . He became a klepht at a very young age and ran a large klepht group mainly between 1787 until 1805 when founded under the leader by the name of Zacharias . Together with the doctor and the lieutennant Tzimiko he first fought with Mahmud Bey from Mystras where he was trained and continuously left with his horse . He participated in many battles against the Ottoman Turks until 1805 when he was hanged . He has a statue in Marouda Square in Patras today ., The Ottoman Empire ('; Modern Turkish: ' or '), also known as the Turkish Empire, Ottoman Turkey, was an empire founded at the end of the thirteenth century in northwestern Anatolia in the vicinity of Bilecik and Söüt by the Oghuz Turkish tribal leader Osman. After 1354, the Ottomans crossed into Europe, and with the conquest of the Balkans the Ottoman Beylik was transformed into a transcontinental empire. The Ottomans ended the Byzantine Empire with the 1453 conquest of Constantinople by Mehmed the Conqueror., Klephts (Greek , "kléftis", pl. , "kléftes", which means "thief" and perhaps originally meant just "brigand") were highwaymen turned self-appointed armatoloi, anti-Ottoman insurgents, and warlike mountain-folk who lived in the countryside when Greece was a part of the Ottoman Empire. They were the descendants of Greeks who retreated into the mountains during the 15th century in order to avoid Ottoman rule. They carried on a continuous war against Ottoman rule and remained active as brigands until the 19th century., Armatoloi (pronounced "ar-ma-to-LEE"; Greek "plural" ; "singular" Armatolos, ; also called Armatoles in English) were Christian Greek irregular soldiers, or militia, commissioned by the Ottomans to enforce the Sultan's authority within an administrative district called an Armatoliki (Greek "singular" ; "plural" Armatolikia, ). Armatolikia were created in areas of Greece that had high levels of brigandage (i.e. klephts), or in regions that were difficult for Ottoman authorities to govern due to the inaccessible terrain, such as the Agrafa mountains of Thessaly, where the first armatoliki was established in the 15th century. Over time, the roles of the armatoloi and klephtes became blurred, with both reversing their roles and allegiances as the situation demanded, all the while maintaining the delicate status-quo with the Ottoman authorities. , Greece (' ), officially the Hellenic Republic (Greek: ' ), historically also known as Hellas ("" ), is a country in southeastern Europe.
