Their success prompted them to declare Irish independence. By the morning of the 25th, they controlled most of the city.
British response came that evening, and by the 29th the rebellion was no more. It's leaders, who survived, were executed for being traitorous rebels, but to the Irish they became martyrs.
Armed riots continued and in 1921, twenty-six of the thirty-two counties of Ireland won independence. In 1949, they became a totally separate republic. The other six counties, would remain under British rule though.
The Irish Republican Army was formed in the north, and in the 60's civil unrest began. A three way conflict began, as the IRA fought the British army, and Irish Catholics and Irish Protestants fought each other.
Peace talks began in the 90's, but it took til 2005 for a cease fire to happen. Twas then that the IRA pledged to lay down arms, and seek their goals purely through peaceful means.
Til this day, the Easter Rebellion is credited as being the birth of Irish independence.
