Rój (German: Roy) is a district in the south-west of Żory, Silesian Voivodeship, southern Poland.
The medieval name Ray, denoted a paradise, it was later pronounced by locals (see Silesian dialects) as Roj, which later transformed into Rój, literally a swarm of bees.
The village was first mentioned in a Latin document of Diocese of Wrocław called Liber fundationis episcopatus Vratislaviensis from around 1305 as item in Regno Dei id est Ray ex ordinacione datur ferto singulis annis.[1] [2]
After World War I in the Upper Silesia plebiscite 335 out of 375 voters in Rój voted in favour of joining Poland, against 40 opting for staying in Germany.[3]
In years 1945-1954 the village was a part of gmina Boguszowice.
