Seyoum, Mulugeta (PhD)Berhan, Tewolde-2021-03-252023-11-302021-03-252023-11-302010-06http://etd.aau.edu.et/handle/123456789/25687The research aims at exploring the historical contributions of Giidlii Abaw wa-AlJaw to its period, that is, to the fourteenth and fifteenth century. In addition, it tries to present philological and linguistic analysis of the GiidL This thesis incorporates six chapters: chapter one introduction, chapter two historical analysis, chapter three philological analysis, chapter four linguistic analysis, chapter five translation of some selected texts of the Gddl and chapter six conclusion and recommendation. Chapter one deals with the method I employed in conducting my research in qualitative research, that is, document analysis. Chapter two explains about the cause of the Stephanite movement. The massive persecution of this sect most probably happened due to refusal to prostrate to the King, Zdr'a Ya'~qob. Chapter three provides some philological elements such as adiaphoric errors and obelos. Chapter four presents the linguistic changes that exist in the Gddl which is written about 450 years back. There are phonological, morphological and syntactic changes or problems in the Gddl. In chapter five, I selected some texts deliberately and gave equivalent translation for them. I did it to let the reader get a brief know how on the movement. I didn't translate all as it is bulky which is 314 pages or 162 folios. My conclusion holds that the cause of the Stephanites' persecution was neither political nor economical. In the researcher's view, it was rather religious. Lastly, recommendations are given.enHistoricalLinguistic AnalysisThesis
