Ali Rıza Bey, born in Thessaloniki Usturian in 1888, is a Republican intellectual who worked as a teacher and inspector in various provinces of Anatolia. In addition, the author, who also held state duties such as the district director and the deputy district governor, also carried out museum studies. Although he wrote many articles and books including compilations and ethnographic studies in various magazines and newspapers, his theater writing is not well known. The subject of the study, Ali Rıza Yalgın’s work named Yeşil Yurdun Sisli Günlerinden (Kanlı Örnek) is a three-act school play. The work tells the heroism of the patriotic Prudence (Top Lieutenant) İbrahim Bey during the Greek occupation and the Greek persecutions in Bursa and its surroundings. In addition to these, the traces of the Greek invasion in his soul and the plight of İbrahim Bey’s father, Bursa notables and a member of Maksem Neighborhood, Hacı Ömer Bey, who lived with feelings of regret and hatred, are handled in the play. In his plain plays, he aims to educate the youth and instill a sense of patriotism in them. During the period when Yalgın was active as a writer, it was encouraged to write and exhibit educational school plays. In addition, in these years, non-formal education through theater activities and writing plays by giving representations in both community centers and schools were encouraged. The work, located in Bursa İnebey Manuscripts Library, Haraççıoğlu, Nr: 6432, was written in a lined notebook with 57 pages and 21 lines in rika script. There is also a typewritten copy of the work in the same library. According to the information given on the first page of this copy, the work was intended to be published, but this work was abandoned because it could not be agreed with the printer. Unfortunately, there is no information about whether the play was played or not. The play was completed on February 5, 1338 / February 5, 1922, and information on the historical process of the occupation is also given in the play. In the study, the writing and typewriter copy of the play was introduced and information was given about the content of the play and the historical events in the play. In this direction, the work, which is an example of Turkish children’s theater and also a very valuable historical document since it was written during the occupation of Bursa, was presented to the use of today’s readers in order not to be forgotten on the library shelves.
