Markos Botsaris (; 1790 – 21 August 1823) was a Souliot chieftain, general of the Greek revolutionary army and hero of the Greek War of Independence. He played a key role in relieving the First Siege of Missolonghi in 1822–1823 and was awarded the title of General of Western Greece by the revolutionary Greek government. He was killed during the Battle of Karpenisi and was buried in Missolonghi with full honors. Today Botsaris is among the most revered national heroes in Greece.
Family and early life (1790–1820) Markos was born in 1790 in Souli, the fifth child of Kitsos Botsaris from his first marriage with Chrysoula, one of the daughters of Papazotos Yotis, the priest of Variades, a village of Lakka (Tsarkovista). The Souliots spoke Albanian originally, but during the eighteenth century they learnt to also use Greek via communication with their mostly Greek-speaking surroundings. Marko's native language was a dialect of Albanian and not Greek, as such, he was known by his Albanian name, Marko Boçari () rather than by Markos Botsaris, though he certainly also spoke Greek. Markos was born into the most powerful Souliot fara, the Botsaris clan (, ), which up until the end of the Greek Revolution was known in Greek as "Botsarates" (, ). According to an unclear narrative recorded by Christoforos Perraivos, which is considered implausible by contemporary historiography, the Botsaris clan came from the village of Dragani (today Ambelia), near Paramythia. Botsaris clan were one of the oldest clans which settled in Souli. Their name may be related to the Albanian word buzë as hinted by written variants of the name in the 19th century. The patron saint of the clan was Donatus of Euroea. The Botsaris had built a church dedicated to Saint Donatus in the areas of Souli they directly controlled.
They were biggest of the Souliot clans which negotiated and eventually collaborated with Ali Pasha. Perraivos (1815) is one of the contemporary historians who recorded the collaboration with Ali Pasha since the spring of 1800. Perraivos attributes this shift to the "madness of greed" of George Botsaris (grandfather of Markos Botsaris) whom he calls a "paid traitor". Other historians of the 19th century follow the same assessment. In modern historiography, the explanation of his political stance through "greed" is considered an oversimplification. Like all other Souliot clans, the Botsaris first and foremost worked for the interests of their own clan, and sought to improve the wealth and political position of their clan, hence the stance of George Botsaris and all Souliot leaders is interpreted in this framework. For the Botsaris clan, since 1799 when Ali Pasha took control of the villages of Lakka Souli which were previously under the sphere of influence of the Botsaris clan, integration in the Ottoman system was the only viable political option. In 1800, George Botsaris received a large sum and the position of the armatolos of Tzoumerka, and the Botsaris clan left Souli and settled in Vourgareli of Arta. This was the first time that a Souliot clan became part of the Ottoman political system. The departure of the Botsaris clan weakened Souli as they were a significant part of its force and Souli was led to surrender to Ali in 1803, after a three-year siege. Thirteen year-old Markos used his limited literacy to record his anguish for the besieged Christians of Souli in a remembrance note of November 3 on the book cover of a Menaion of a chapel of Palaiokatouna (Voulgareli).
After the surrender of Souli, Souliot clans chose divergent paths but many were ultimately led to move to the Ionian Islands and in south Greece. Kitsos Botsaris who had succeeded his father as armatolos of Tzoumerka became a target. Botsaris gathered his clan and 1,200 Souliots who retreated to Agrafa. In January 1804, they were attacked by Ali Pasha's army under Beqir Bey with support from the local armatoloi Zikos Michos, Tzimas Alexis and Poulis. As the Botsaris clan was given the important armatolik of Tzoumerka, other armatoloi had targeted them. The Souliots were besieged for 3 months on the grounds of the monastery of the Assumption of Mary. In the final battle, on 7 April, most Souliotes were killed and of those who survived many were taken hostage. About 80 escaped from this battle. Ali Pasha at the same time published a firman which targeted the Botsaris clan which was hunted down. Kitsos Botsaris and his family with a few others managed to escape to Parga and later settled in the Ionian Islands. He returned to the Pashalik of Yanina in 1813 when Ali Pasha gave him again the armatolik of Tzoumerka but as soon as he returned he was murdered by a Gogos Bakolas.
