Final answer:
The Easter Rising took place on April 24, 1916, when Irish Nationalists launched an insurrection against British rule in Dublin, which despite its failure, paved the way to the establishment of the Irish Free State in 1922.
Step-by-step explanation:
The Easter Rising was a pivotal event in Irish history that took place on April 24, 1916. It involved Irish Nationalists who were discontent with British control and the postponement of Home Rule, leading them to stage an armed insurrection in Dublin during Easter week. Despite the absence of expected German aid in terms of weapons, the Irish Republican Brotherhood, along with other factions advocating for Irish independence, continued with their plans. The proclamation of an Irish Republic and the seizure of key locations marked the beginning of the uprising. However, the British response was swift and superior in military might, leading to the suppression of the revolt and the execution of its leaders. This event, though unsuccessful, was critical in fostering a sense of nationalist sentiment and eventually contributing to the formation of the Irish Free State in 1922.
