The decades following the Second World War saw strong technological development and economic growth. They also saw "the advent of technology education", a period of extensive curriculum development in this field. But what was done and why? In order to obtain a better understanding of the historical roots of technology education, in this study the mid-century school reforms in Sweden are examined and, more specifically, the birth of the new subject of Technology ("Teknik") in compulsory schools. In this article, the political forces driving the introduction and shaping of this new subject are emphasised. In a time of rapid transformations of educational systems and labour markets, the term "Teknik" proved to be a useful concept for policy-makers and reform technocrats. However, the subject came to re-create the inequalities of the earlier differentiated school system, despite its presence within the framework of a school "for all".
