中唐时期李唐“联回抗蕃”政策之检讨

Critical Comment on the Tang Court-s Policy of "Uniting the Uyghurs to Resist against the Tibetans" in the Midst of the Tang Dynasty

"联回抗蕃"似乎已成近半世纪来台湾史学界定论,但此一主张并不切合史实。首先,李唐为避免两面作战考虑,与回纥维持传统情谊,解决战马需求,引其援军入靖平乱,且安抚免于生事;其次,归纳历史经验,推断回纥本身势必挺进西域,与吐蕃争雄。回纥与吐蕃其根本利益有潜在性的冲突存在,非因李唐或其外交政策使然。李唐有求于回纥者,内靖乱事多过于牵制吐蕃;再则,有求于蕃,起初在扭转唐回蕃三边形势,后转于平乱,如此较吻合史实。

It seems to have been an established view in Taiwan world of history that ＂the Tang Court used to unite the Uyghurs to resist against the Tibetans＂,but this view doesn＇t agree with the historical fact.The author argues that,first of all,in order to avoid fighting in two battlefields,the Tang court of the Li family managed to maintain its traditional fraternal relation with the Uyghurs to meet with needs for stallions and asked their relief troops to participate in putting down the rebellion to placate them from making trouble.Next,Considering historical experience,it can be inferred that the Uyghurs must by themselves intrude into western China to rival with the Tibetans.Therefore,it is not because of the Tang court＇s or its diplomatic policy＇s partiality,but because of the potential conflict between the Uyghurs and The Tibetans in primary interests.As the historical fact shows,the Tang court needed help from the Uyghurs rather for too much domestic troubles than for distracting the Tibetans.On the contrary,it needed help from the Tibetans first for improving the situation among the Tang court,the Uyghurs and the Tibetans and then for suppressing the rebellion.
