ثيمة (مقاطعة بيزنطية)
ثيمات theme أو ثيماتا (باليونانية: θέματα؛ ومفردها: θέμα، ثيما) كانت التقسيمات الادارية/العسكرية الرئيسية في الامبراطورية البيزنطية الوسيطة. وقد تأسسوا في منتصف القرن السابع في أعقاب الغزو السلاڤي للبلقان والفتوحات الإسلامية لأجزاء من الأراضي البيزنطية، وقد حلت محل نظام المقاطعات الذي أرساه ديوكلتيان وقسطنطين الأكبر. وفي أصلهم، فإن أول الثيمات خُلِقت من مناطق معسكرات الجيوش الميدانية للجيش الروماني الشرقي، وأسماهن تناظر الوحدات العسكرية التي تواجدت في تلك المناطق. بلغ نظام الثيمات أوجه في القرنين التاسع والعاشر، إذ انفصمت الثيمات القديمة وأدت الفتوحات الحديثة إلى خلق ثيمات جديدة. خضع نظام الثيمات الأصلي لتغيرات بارزة في القرنين 11 و 12، إلا أن المصطلح ظل مستخدماً في السياق الاداري والمالي حتى نهاية الامبراطورية.

التنظيم
المصطلح ثيما كان غامضاً، ويشير إلى كلٍ من شكل تراتب عسكري وإلى تقسيم اداري. A theme was an arrangement of plots of land given for farming to the soldiers. The soldiers were still technically a military unit, under the command of a strategos, and they did not own the land they worked as it was still controlled by the state. Therefore, for its use the soldiers' pay was reduced. By accepting this proposition, the participants agreed that their descendants would also serve in the military and work in a theme, thus simultaneously reducing the need for unpopular conscription as well as cheaply maintaining the military. It also allowed for the settling of conquered lands, as there was always a substantial addition made to public lands during a conquest.
The commander of a theme, however, did not only command his soldiers. He united the civil and military jurisdictions in the territorial area in question. Thus the division set up by Diocletian between civil governors (praesides etc.) and military commanders (duces etc.) was abolished, and the Empire returned to a system much more similar to that of the Republic or the Principate, where provincial governors had also commanded the armies in their area.
The following table illustrates the thematic structure as found in the Thracesian Theme, c. 902-936:
