This article studies the institutionalization of disciplinary history teacher training in the Chilean educational system, in the context of the expansion of public secondary education during the second half of the nineteenth century. Its aim is to examine the origins of the teaching profession specialized in the teaching of history, at foundational moments of its historical trajectory as a disciplinary teaching body, with special emphasis on its beginnings at the Instituto Pedagogico. Based on a historical, bibliographical and documentary methodological design, the study postulates and argues that the foundational impulse of the history teaching profession is based on the formative demands of the humanistic teaching plan that was instituted for the Chilean high school, since the 40's of the 19th century, and on a discursivity favoring a specialized teacher training promoted by nineteenth-century educationists.
