Modu Chanyu冒顿单于(Modu Chanyu?一公元前174)秦汉之际著名匈奴单于,军事统帅。前209一前174年在位。本为头曼单于太子,其父欲废之而立少子,使至月氏作人质,欲借月氏人杀之。冒顿盗马逃归,头曼以为壮勇,令统领万骑。冒顿乃加紧训练部众,至时机成熟后杀头曼,自立为单于。时东胡强盛,闻冒顿自立,有轻视意。先后遣使索要冒顿之千里马、妻妾,冒顿皆应允。东胡益骄,索要边地千余里。’爵顿乘东胡不备,倾力袭击,灭东胡。继而西逐月氏;南并楼烦、白羊两部,侵及燕、代;北服浑痪、屈射、丁零、高昆、薪犁诸国。匈奴由此强盛,设左右贤王等24长,称雄于大漠南北。汉高祖六年(前201),冒顿率部围马邑(今山西朔州),迫韩王信投降。复驱众攻太原郡,兵锋及于晋阳(今太原西南)。次年,闻刘邦欲击己,乃隐匿少壮,示以老弱之人和赢瘦之畜,引诱汉军至平城(今大同东北),以40万骑兵将刘邦君臣围困于白登山(平城东北)达七日之久。后屡次结连汉朝叛将,袭扰汉朝边郡。九年,与汉和亲,侵掠稍止。汉文帝前期,冒顿所部复占河南地(今内蒙古河套南伊克昭盟一带)。继遣右贤王再次攻逐月氏,降服楼兰、乌孙、呼揭等26国(部族),致书汉朝,自称“匈奴大单于”,炫耀武功。(杨宗平)
