A decade of popular militancy immediately preceded and decisively shaped the formation of the Irish Free State and the drafting of the Irish Free State Constitution in 1922. What has been termed the ‘Irish Revolution’ (1913–23) adhered to the conservative postcolonial trajectory outlined and critiqued by the Afro-Caribbean psychiatrist and theorist Franz Fanon, in which a nationalist party gradually substituted itself for a mass anticolonial and social movement. The Sinn Féin party effectively reasserted the principle that the masses are incapable of governing themselves, notwithstanding ample evidence to the contrary in the form of self-governing communities, arbitration courts, and soviets. This had important implications, most notably in terms of the ‘detached complicity’ between nation-building elites and the established market economy. Sinn Féin's leadership did not view the classic laws of market, property, and contract as problematic per se, rather their having being formerly skewed against ‘the Irish people’. Thus, its constitutionalism envisaged the silent reproduction of market law and the strident defence of an Irish nationalist, often specifically Catholic, culture. This national constitutionalism, as was common in many postcolonial jurisdictions, was most clearly expressed in family law, notably resulting in a remarkably enduring defence of patriarchal relations.

Popular militancy in Ireland, notably between 1917 and 1923, occurred alongside a global wave of worker militancy in the aftermath of the Russian Revolution of 1917. The nationalist movement's waging a guerrilla campaign against British rule occurred alongside Sinn Féin's creation of a state within a state while broad swathes of civil society boycotted established institutions and disrupted existing patterns of domination.
