STUDY OF TAGMA OR PRAETORIAN REGIMENTS

希腊语“tagma”一般指军事单位。然而，在拜占庭中期，塔格马从8世纪中期开始作为首都或首都附近的禁卫军出现。直到9世纪初，皇帝都组织了四名侍从，他们主要扮演着支持皇帝或干预中央政府政治进程的角色。我们可以意识到，在9世纪中叶，tagma作为一种官方军事力量在中央政府中形成。在本研究中，为了获得更可信的骑兵tagma力量强度数据，我们使用了Constantine VII Porphyrogenitus在10世纪编辑的“De cerimoniis aurae byzantinae”的文本。这篇文章包含了一些关于重新征服克里特岛的军事远征的资料。根据文本，每个骑兵大队的士兵驻扎在君士坦丁堡附近，大约有1000 - 1500人的兵力。我们数了一下，这4个塔玛塔总共有4000到5000个。所以塔玛塔可能太小，不能称为拜占庭帝国的“中央力量”

Greek "tagma" means military unit in general. The tagma in the Middle Byzantine Period, however, appeared from the middle of the 8th century on as a praetorian regiment in or near the capital. Until the beginning of the 9th century, 4 cavarly tagmata had been organized by emperors and they played mainly the roles to back up emperors or to intervene to political process in the central government. We can be aware of formation of tagma as an official military force in the central government in the middle of the 9th century.In this research to obtain more trustworthy data about force strength of cavalry tagma, we use the text of "De cerimoniis aurae byzantinae", which was edited by Constantine VII Porphyrogenitus in the 10th century. The text contains some data about the military expeditions to reconquer the Crete. According to the text, soldiers of each cavalry tagma were stationed near Constantinople, and have about 1,000-1,500 force strength. We count the total of the 4 tagmata about 4,000-5,000 in total. So probably the tagmata were too small to call "central forces" of the Byzantine Empire.
