Excerpts from Books and Wikipedia
"After the introduction of the Local Government (Ireland) Act 1898 which broke the power of the landlord-dominated "Grand Juries", passing for the first time democratic control of local affairs into the hands of the people through elected Local County Councils, the debate over full Home Rule led to tensions between Irish nationalists and Irish unionists (those who favoured maintenance of the Union). Most of the island was predominantly nationalist, Catholic and agrarian. The northeast, however, was predominantly unionist, Protestant and industrialised. Unionists feared a loss of political power and economic wealth in a predominantly rural, nationalist, Catholic home-rule state. Nationalists believed they would remain economically and politically second-class citizens without self-government. Out of this division, two opposing sectarian movements evolved, the Protestant Orange Order and the Catholic Ancient Order of Hibernians." [Wikipedia]
