The potato famine was in full swing and the young Irelander Rebellion started in south tipperary, there had been other rebellions but the potato famine and the empires lack of help and sympathy to the irish and the feelings of rage in the country exploded.
The attempt to kill the ringleaders early in the rebellion failed and the rebellion seized the entire Island, two years of Famine and brutal fighting later the british left and Ireland became an independent republic, but what if this rebellion had failed?
How would Irish and world history change?
