Every year on March 25th, Greece honors and celebrates the uprising of the Greeks against Ottoman oppression, for freedom and self-determination.
 

It is the most important date in the history of Modern Greece, as the starting point of national independence and also a turning point for changing the entire geopolitical map of the European continent.
 

The period preceding the Greek Revolution is an era of revolutions on a global level.
 

After the War of American Independence (1776), the French Revolution (1789), and the revolutions in Italy, Spain, and Austro-Hungary, the ideological groundwork of nations' liberation had been laid. 
 

Away from the eighteenth-century model of multi-ethnic, autocratically ruled empires and towards the twentieth-century model of the self-determination of nation-states.
 

It was in this climate that the idea of greek liberation was born and fermented.
 

The Greeks were not the first who talked about national independence.
 

But it was in Greece and by the Greeks that this experiment was first put into practice in Europe.
 

It was the revolution in Greece, that broke out in the spring of 1821, the first liberal-national movement to succeed, against the Ottoman empire causing the first breach in the legitimization of Ottoman power in southeastern Europe.
 

It was an unequal struggle for the Greeks, in terms of armament, training, and number of soldiers.  
 

It was a long war of heroic battles, destruction and many sacrifices of the Greeks until the official recognition of Greece as an independent state in 1830 by the London Protocol.
 

The Ottoman forces with the assistance of Ibrahim Pasha of Egypt managed to significantly limit the revolution many times, but the fall of Messolonghi in 1826, combined with the movement of Philhellenism, contributed to the change of the diplomatic attitude of the European Great Powers, which had faced with discontent the outbreak of the revolution.
 

The Greek Revolution is the most important chapter in the history of modern Greece that teaches and inspires.
 

The Greek nation first, stood up to an Empire and fought it without an organized army and achieved its national independence, relying mainly on its cultural and spiritual powers, as over the centuries it continued to create civilization and demonstrate an uninterrupted political maturity compared to other enslaved nations.
