This article introduces a novel data set on the agenda of the Turkish legislature and political parties. Using the Comparative Agendas Project approach, we trace political issue attention over an 11–year-period (2003–2013). By topic coding various political activities, this approach illustrates the dynamics of the Turkish political agenda and the issue attention of the political parties, and, therefore, sheds new empirical light on the dynamics of Turkish legislative politics and party competition. In this article, we explain the construction of the data set from data collection to coding, describe its features, and provide examples of possible applications.
