The capture of Psara Island by Egyptian forces in June 1824 was a pivotal moment in the Greek War of Independence, which had begun in 1821. Under the leadership of Mohammad Ali Pasha, the Egyptian Army was dispatched to support the Ottoman Empire in quelling the Greek revolt. Psara, a small but strategically vital island, played a significant role in the Greek revolutionary efforts, mainly due to its maritime significance and the local population's commitment to the cause of independence. The Greek resistance was fierce, but they ultimately could not withstand the well-organized and well-resourced Egyptian forces.

This event also signified the increasing international dimensions of the conflict, as Egypt's involvement extended the fight beyond local and national boundaries. The battle for Psara was fierce, leading to heavy casualties on both sides. The fall of the island gave the Egyptians control over critical shipping lanes, which allowed them to reinforce their logistics and pressure other key areas of resistance in the Greek territories. Furthermore, the loss of Psara played a psychological role for the Greeks, who saw their stronghold fall and lost the morale of their forces.

Besides the military implications, the capture of Psara also sparked a response from various European powers. The ongoing conflict raised concerns about the balance of power in the region and prompted discussions regarding intervention. The independence of Greece was a cause célèbre for many European intellectuals and activists, thereby complicating the geopolitical landscape. The fight for liberation didn't end with the capture of Psara; rather, it motivated the Greek resistance to regroup and continue their struggle for sovereignty, eventually leading to their eventual independence in the following decades.
