How did protective tariffs fit Eamon de Valera’s plan for Irish self-sufficiency?

Eamon de Valera utilized protective tariffs as a central component of his program for national self-sufficiency during his tenure as head of the Irish government.1

Following the onset of an "economic war" with Great Britain in 1932—triggered by his decision to withhold land-purchase annuities—de Valera implemented these tariffs to shield and foster the growth of young domestic industries. By restricting foreign competition, these protective measures were intended to supply the home market and provide essential employment opportunities for the Irish population. This strategy was part of a broader, austere vision for an independent, self-sufficient Ireland that sought to reduce economic reliance on external powers.12
