The capture of Tripolitsa on September 23, 1821, was one of the most important early military successes of the Greek War of Independence. It also became one of the conflict’s bloodiest episodes, as large numbers of Muslim and Jewish inhabitants were killed after Greek revolutionary forces entered the city.
Tripolitsa, known today as Tripoli, was the administrative and military centre of the Ottoman Peloponnese, or Morea. Its strategic position made it a major objective for the Greek revolutionaries, who had launched their uprising against Ottoman rule earlier that year.
A months-long siege
Greek forces under commanders including Theodoros Kolokotronis surrounded the city during the spring of 1821. The siege lasted for several months, gradually cutting off supplies and weakening the Ottoman defenders.
The population inside the walls had increased significantly as Muslims from surrounding areas sought refuge in Tripolitsa after the outbreak of the revolution. Contemporary and later estimates of the city’s population vary considerably. Sources also differ over the number of Muslims, Jews and armed Ottoman troops inside the city.
By September, food shortages and military defeats had left the defenders in an increasingly difficult position. Negotiations also took place over the departure of some groups from the city.
On September 23, Greek revolutionaries gained entry through the Nafplia gate after the defensive position there was left unguarded. The gates were opened and Greek forces entered Tripolitsa. The capture represented a major strategic victory, removing the Ottoman administrative centre of the Peloponnese from Ottoman control.
Mass killings followed the capture
The military victory was followed by widespread killings, looting and destruction.
Historical accounts describe Muslim inhabitants, including women and children, as among those killed after the city fell. Jewish residents were also caught up in the violence. A modern academic study of the Greek Revolution notes that Tripolitsa was among several locations in the Peloponnese where Muslim populations were massacred during the conflict.
Estimates of the number killed vary substantially. Figures cited in historical accounts range from around 6,000 to 15,000 Muslim and Jewish civilians, although other contemporary and later accounts have produced significantly higher numbers. The uncertainty reflects differences in estimates of the population inside Tripolitsa, the distinction between civilians and combatants, and the difficulty of establishing reliable casualty figures for the period.
Historian Thomas Gordon, who reached the city shortly after its fall, estimated that about 8,000 Muslims had been killed. More recent scholarship also describes the sack as one of the most severe atrocities committed during the Greek Revolution.
Accounts from the Greek side
The scale of the violence was also recorded by Greek participants.
In his memoirs, Kolokotronis described killings continuing for several days and acknowledged the deaths of men, women and children. His account also reflects the deep resentment created by Ottoman rule and earlier violence against Greek populations.
The events were not simply a military engagement between Greek revolutionaries and Ottoman forces. The violence extended to the civilian population, making the fall of Tripolitsa a significant example of the wider cycle of massacres and reprisals that accompanied the Greek War of Independence.
A study published in Historein notes that atrocities were committed by both sides during the conflict, while Ottoman reconquests also involved massacres and executions of Greek populations. It identifies Tripolitsa among the places where Muslim civilians were killed after Greek forces captured towns and strongholds.
A turning point in the Greek Revolution
Despite the atrocities that followed, the capture of Tripolitsa had major military consequences for the Greek revolutionary movement.
The city was the main Ottoman administrative centre in the Peloponnese. Its fall gave the revolutionaries control over much of the peninsula and provided them with weapons and supplies. A historical overview published by the Western Greece 2021 project describes the capture as the most significant military event of the first year of the Revolution.
The victory therefore became an important symbol of the Greek struggle for independence, while the massacre that accompanied it remains one of the most controversial and tragic episodes of the war.
Today, September 23 is commemorated in Tripoli as the anniversary of the city’s fall. The historical record, however, also preserves the darker side of that victory: the destruction of much of Tripolitsa’s Muslim and Jewish population in the violence that followed its capture.
