254 Gorun-Kovács Blanka: A diószegi és székelyhídi görög-katolikus... The Imperial charter of the Greek Catholic traders in Diószeg and Székelyhíd Blanka Gorun-Kovács In the territory of Bihar county the Greek traders living here united into trading companies at Várad, Diószeg and Székelyhíd. The so-called “Greeks” (in reality the Serbs, Macedonians, Romanians and Greeks arriving from the Turkish Empire) received a new privilege from Károly III., on the 8-th August 1740, probably at the request of Johann Franz Gottfried Dietrichstein. Dietrichstein had an interest in the making out of the charter for the Greek traders in Diószeg and Székelyhíd, for to be sure Diószeg belonged to his land holding from 25-th April 1732, then Székelyhíd as well from 15-th April 1735. The charter of year 1740 differed from the earlier privileges granted to the Turkish serf traders in two important questions: the first was the peculiarity that in general the privileges were made out by the land owners, this however, by the ruler himself, while the second difference was that an important condition for becoming members of the company, was the traders becoming Greek Catholics (“graeci ritus unitis”). This point had an important role in the religious life, and the probable realisation of this is attested to by the fact that the first Greek Catholic bishop in Várad - Meletie Kovács - also came from Diószeg.
