Turkish Design History Society is a platform that was informally established at a meeting held at İzmir University of Economics on August 11, 2004. Initially founded as an informal platform, the Society was subsequently formalized on June 2, 2014 with the application made by a group of 25 founding members who were all designers, academics and researchers carrying out their annual symposium activities under the title of 5T: Turkish Design History Society at Yaşar University between the years 2011-2014. As naming the Society “Turkish” required an exceptional application, a fresh title was adopted and it began to operate under the name of 4T Design and Design History Society Association.
