Id Al Fatar (Id-ul-Fitr)
Id Al Fatar (Id-ul-Fitr) means the 'festival of breaking the fast'. The fast of Ramadan is broken with special prayers and festivities. 'Fitr' is derived from the word 'fatar' meaning 'breaking'. Another connotation suggests that it is derived from fitrah or 'alms'. Certain Sunni Muslims believe that fitr comes from fitrat meaning 'nature' and Id-ul-Fitr is the celebration of god's magnanimity in providing nature to man. Celebrated on the first day of the new moon in Shawwal, it marks the end of Ramadan.
March 2 Victory of Adwa
The Battle of Adwa was fought on 1 March 1896 between Ethiopia and Italy near the town of Adwa, Ethiopia, in Tigray. It was the climactic battle of the First Italo–Ethiopian War.
Of all the African powers, only the ancient kingdom of Ethiopia remained completely free from European domination by the end of the 19th century. This was no accident of history; Ethiopia secured its sovereignty by inflicting a decisive and humiliating defeat upon the Italian invaders at Adowa (or Adwa) on March 1, 1896. The battle at Adowa was, at the time, the greatest defeat inflicted upon a European army by an African army since the time of Hannibal, and its consequences were felt well into the 20th century. As an example of colonial warfare on an epic scale, it cannot be surpassed. As an example of the twin follies of arrogance and underestimation of one's enemies, it should never be forgotten.
