The Greek War of Independence began with a powerful proclamation on March 25, 1821, intertwining national aspirations with religious significance as the Orthodox Church celebrated the Annunciation. This dual meaning rallied support among Greeks, uniting various factions against the Ottoman Empire, which had ruled Greece for nearly four centuries. Initially marked by localized revolts, the uprising spread rapidly as leaders such as Alexandros Ypsilantis, Bishop Germanos of Patras, and others called for liberation from foreign oppression. The call to arms resonated in the Peloponnese and beyond, leading to widespread uprisings across the region.

The revolution was characterized by significant battles, including those at Kalamata and Tripolitsa, where Greek forces showed resilience and determination. The struggle was sustained over several years, drawing on both traditional guerrilla tactics and organized military strategies. The burgeoning movement aroused international support, inspiring Philhellene volunteers and prompting governments to consider intervention. As the conflict escalated, the Greek fighters made sacrifices, often faced with brutal reprisals from Ottomans, but their resolve and unity grew stronger.

Significantly, the beginning of this war brought attention to the plight of Greeks and laid the foundation for future alliances. The declaration of Greek independence not only marked a pivotal moment in the country's calendar but also signified a broader European awakening towards nationalism and self-determination. The commitment to the cause inspired future generations to cherish the ideals of freedom and national identity.
