In 1916, with the hated English overlords distracted by the First World War, a group of Irish revolutionaries decided that the time was ripe to rise up, overthrow the Sassenach and declare an independent republic of Ireland. However, the Irish forces were massively outnumbered by their colonial rulers, and to add insult to injury, the English also had a massive technological superiority.
The uprising began on Monday, March 24 of 1916 in Dublin – the day after Easter. It would last for a grand total of six days before it was put down. Most of its leaders were captured, and thence imprisoned or executed for their parts in the revolt. However, as the first major uprising since 1798, it reinvigorated the Irish independence movement, and the next – and ultimately successful – Irish rebellion began only three years later.
