In his 2005 book, Speros Vryonis documents the direct role of the Demokrat Parti organization and government-controlled trade unions in amassing the rioters that swept Istanbul. Ten of Istanbul's 18 branches of the "Cyprus is Turkish" Association were run by DP officials. This organization played a crucial role in inciting anti-Greek activities. Most of the rioters came from western Asia Minor. His case study of Eskişehir shows how the party there recruited 400 to 500 workers from local factories, who were carted by train with third class-tickets to Istanbul. These recruits were promised the equivalent of 6 USD, which was never paid. They were accompanied by Eskişehir police, who were charged with coordinating the destruction and looting once the contingent was broken up into groups of 20–30 men, and the leaders of the party branches.
