29 October 2023 marked the centennial of the Republic of Turkey. Over the past hundred years, the country has undertaken major institutional changes, experiencing periods of democracy and non-democracy, bicameralism and unicameralism, parliamentary and presidential systems, and majoritarian and proportional electoral systems. This unique variation provides excellent opportunities to study various theoretically important research questions. This article introduces a novel dataset of the entire population of legislators and their parliamentary activities in Turkey over the past century. The dataset includes detailed information on (i) election results by districts, (ii) the sociodemographic and political backgrounds of 12,500 legislators, (iii) the frequency with which legislators made speeches, asked questions and introduced private members' bills, and (iv) the content of these political activities (i.e., the policy area focus) from the period of 1920-2023. I demonstrate the usefulness of the data through descriptive analyses in three areas, political elites across space, political elites across time, and the policy prioritization patterns in the legislature. I conclude by suggesting areas of research for future studies.
