Butt had failed to win substantial concessions at Westminster on the things that mattered to most Irish people: an amnesty for the Fenians of 1867, fixity of tenure for tenant-farmers and Home Rule. Although they worked to get Home Rulers elected, many Fenians along with tenant farmers were dissatisfied with Butt's gentlemanly approach to have bills enacted, although they did not openly attack him, as his defence of the Fenian prisoners in 1867 still stood in his favour. However, soon a Belfast Home Ruler, Joseph Gillis Biggar (then a senior member of the IRB), began making extensive use of the ungentlemanly tactic of "obstructionism" to prevent bills being passed by the house.
