Tourism crises caused by terrorism are characterised by a sharp decline in inbound tourism and a severe deterioration of destination image. Between 2015 and 2017, Turkey suffered terrorist attacks and political incidents in major cities such as Istanbul, Ankara, Gaziantep, and Şanlıurfa. This paper explores crisis-related factors and their influence on destination image and tourism demand with a series of three studies adopting both primary data collected from tourism managers and secondary data analysis of tourism statistics. Study A explored the adapted measurement tool's reliability and validity to define the factors related to crisis impacts. Study B involved CFA to validate the dimensions of measurement tools and regression analyses to examine their influence on destination image and tourism demand. Study C included a comparison of the tourist arrival and expenditure statistics from 2014 to 2019 with a secondary data analysis. Study A showed that the long-term effects of crises caused by terrorism must be evaluated in structural and political dimensions. Study B indicated that both factors affected destination image negatively, while only structural problems influenced international and domestic tourism demand. Study C supported the effect of both factors on tourist arrivals and tourism income, involving the analysis of tourism statistics.
