エジプト第25王朝
In the seventh century BC, Scythians penetrated from the territories north of the Black Sea across the Caucasus. The early Scythian kingdoms were dominated by inter-ethnic forms of dependency based on the subjugation of agricultural populations in eastern Transcaucasia, plunder and taxes (occasionally, as far as the region of Syria), regular tribute (Media), tribute disguised as gifts (Twenty-fifth Dynasty of Egypt), and possibly also payments for military support (Neo-Assyrian Empire).
