The political crisis heightened tensions in Belfast and rioting took place in July 1911. Conservative Party leader, Andrew Bonar Law visited Belfast on Easter Tuesday 1912. Special trains brought over 100,000 Unionist demonstrators who paraded passed the stage in turn at the Balmoral Grounds in Belfast. Those gathered then observed prayers lead by the Church of Ireland Archbishop of Armagh and the Presbyterian Moderator. The largest Union Jack ever created was the unfurled and Bonar Law gave a speech comparing contemporary unionists with their forebearers who were besieged in Derry in 1689. Two days later, on 11 April 1912, Prime Minister Herbert Asquith introduced the Home Rule Bill in the Commons. The Third Home Rule Bill was proposed by the Liberal government and would have granted limited autonomy to an all-Ireland Irish Parliament.
