In my thesis I would like to make clear those steps that led to the Easter Rising and prove that its consequence was the formation of Northern Ireland. The stages are much more important than the events happening during the Easter Rising. The process was long and time-consuming but the effect is undeniable. The Easter Rising was the end of the movements which began in the 19th century, but at the same time it was the beginning of a new theatre of the Anglo-Irish history. In my opinion, the insurrection and its antecedents have unquestionable roles.
