When they seized the General Post Office in Dublin on Easter Monday, 24 April 1916, the leaders of the Rising proclaimed a free Irish Republic in which the egalitarian idea was centrally enshrined. The Proclamation, which was first read out by Patrick Pearse on the steps of the GPO just after noon, declared the rights of the people of Ireland to be sovereign. It looked forward to the establishment of a native Government elected on the democratic principles of self-determination and government by consent. The 1916 Rising set in train an unstoppable process which led to the separation of Ireland from Great Britain.
The events of 1916 must be viewed against the backdrop of the broader nationalist movement, the convictions of those who opposed any weakening of the link with the Crown and the momentous events being played out on the battlefields of Europe in one of the bloodiest conflicts that the world had ever seen. It should be noted that the continuing threat of conscription brought about by the manpower needs of the war consolidated the growing rift within the popular opinion. The ongoing frustration within Nationalist Ireland at the lack of progress on Home Rule, the prospect that it would not even be for the whole island, reinforced by the refusal of the British War Office to allow the creation of a distinctly Irish Brigade, and its rejection of even an Irish divisional badge, was compounded by the abhorrence of the executions.
Nuair a ghabh siad Ard-Oifig an Phoist i mBaile Átha Cliath Luan Cásca, an 24 Aibreán 1916, d’fhógair ceannairí an Éirí Amach Poblacht na hÉireann a bheadh saor agus a mbeadh an chothromaíocht ina croíghné de. Dearbhaíonn an Forógra, a léigh Pádraig Mac Piarais ar dtús ar chéimeanna Ard-Oifig an Phoist díreach tar éis meán lae, cearta mhuintir ina hÉireann a bheith ceannasach. Bhíothas ag tnúth le Rialtas dúchais a bhunú a bheadh tofa ar phrionsabail dhaonlathacha an fhéinchinnidh agus rialú le toil. Chuir éirí amach 1916 tús le próiseas nach bhféadfaí a stopadh agus as ar lean Éire agus an Bhreatain Mhór a dheighilt óna chéile.
Caithfear breathnú ar imeachtaí 1916 i gcomhthéacs ghluaiseacht náisiúnach níos leithne, tuairimí láidre na ndaoine a bhí in aghaidh aon lagú a dhéanamh ar an nasc leis an gCoróin agus na himeachtaí móra a bhí ar siúl ar pháirceanna an áir san Eoraip i gceann de na coimhlintí ab fhuiltí a fachtas riamh ar domhan. Ba chóir a thabhairt ar aird gur neartaigh baol leanúnach an choinscríofa a bhí ann mar gur theastaigh an oiread daoine le haghaidh an cogadh a throid an scoilt a bhí ag méadú i measc na ndaoine go ginearálta. Bhí an t-éadóchas leanúnach i measc na Náisiúnaithe in Éirinn faoin easpa dul chun cinn ó thaobh Rialtais Dúchais, agus go bhféadfadh sé tarlú nach bhfaigheadh an t-oileán ar fad Rialtas Dúchais, agus diúltú Oifig Chogaidh na Breataine cead a thabhairt Briogáid Éireannach a chruthú, agus fiú diúltú na hOifige sin do shuaitheantas rannánach Éireannach, níos measa fós de bharr na ndaoine a bhí á gcur chun báis.
