With much greater numbers and heavier weapons, the British Army suppressed the Rising. Pearse agreed to an unconditional surrender on Saturday 29 April, although sporadic fighting continued until Sunday, when word reached the other rebel positions. After the surrender the country remained under martial law. About 3,500 people were taken prisoner by the British, many of whom had played no part in the Rising, and 1,800 of them were sent to internment camps or prisons in Britain. Most of the leaders of the Rising were executed following courts-martial. The Rising brought physical force republicanism back to the forefront of Irish politics, which for nearly 50 years had been dominated by constitutional nationalism. It, and the British reaction to it, led to increased popular support for Irish independence. In December 1918, republicans, represented by the reconstituted Sinn Féin party, won a landslide victory in the general election to the British Parliament. They did not take their seats, but instead convened the First Dáil and declared the independence of the Irish Republic, which led to the War of Independence.

The Easter Rising was a failure, but least to two more active campaigns, interrupted by WWII the start of the cold war. These skirmishes and fights kept going until they escalated in the late 1960's depending on what history books you read growing up, you know this as either the Great Cause or The Troubles
