The development of the Irish system of education was, not unlike all critical aspects of Irish identity, fundamentally shaped by its relationship with its colonial neighbour. Prior to Independence in 1922, the system of education promoted was a fundamental part of a strategic effort to ensure cultural assimilation and political socialisation. Control over the education system facilitated the systematic erosion of the native language and culture and the reproduction of colonial values. Following Independence, the system of education promoted was a response to what was perceived as centuries of political, economic, cultural and linguistic domination. However, whether prior to or post-Independence, the pedagogical was often marginalised at the expense of the political. This article focuses on an aspect of Irish education policy which has largely escaped the focus of scholars to date: teacher education policy. It examines the ideological basis underlying the development of a national policy on teacher education from 1831. (Contains 67 footnotes, 1 table and 1 figure.)
