Although the Law on Settlement was expected to operate as an instrument for Turkifying the mass of non-Turkish speaking citizens, it immediately emerged as a piece of legislation which sparked riots against non-Muslims, as evidenced in the 1934 Thrace pogroms in the immediate aftermath of the law's passage. Law No. 2510 was issued on 14 June 1934, and the Thrace pogroms began just over a fortnight later, on 3 July. The incidents seeking to force out the region's non-Muslim residents first began in Çanakkale, where Jews received unsigned letters telling them to leave the city, and then escalated into an antisemitic campaign involving economic boycotts and verbal assaults as well as physical violence against the Jews living in the various provinces of Thrace. It is estimated that out of a total 15,000-20,000 Jews living in the region, more than half fled to Istanbul during and after the incidents. However, although the Law on Settlement may well have actually provoked the incidents’ outbreak, the national authorities did not side with the attackers but immediately intervened in the incidents. After order was restored, the governors and mayors of the provinces involved were removed from office.
