This article discusses the meeting of the Second National Educational Council in 1943, the decisions made about reaching history and the preparation and implementation of histomaps, which was one of the decisions made about the reaching of history. For this purpose, document analyses are used and first hand and second hand resources were reviewed. The endeavor in this Study is to show how one of the council decisions of the first years of the Republic is applied. Hasan Ali Yucel, the Minister of National Education assigned Hamit Zubeyr Kosay for this histomap task. Benefiting from the study of John B. Sparks (1931) named the Histomap: Four Thousand Years of World History" and working with a team, Hamit Zubeyr Kosay developed a histomap compatible to Turkish History in 3 years. This case study is significant as it described the obligation of bureaucrats of the Ministry of National Education in the early 20s of the Republic. The histomap of Sparks by Rand McNally Publishing in the USA has been continuously updated since it was first developed. Unfortunately, since then the mechanisms were not constructed to update histomap of Kosay regarding the changing history course books and programs in Turkey.
