一刘黑■是隋末农民大起义中继承■建德起义事业的重要农民领袖。他对于打击当时的封建统治、特别是唐政权,从而迫使其不得不向农民让步上,曾起了巨大的作用。但目前有些史学工作者,在评价这样一个优秀的农民领袖时,却得出了相反的结论。而且,由于这个不正确的结论,又必然牵涉到全面评价“统一战争”这一总问题上,造成混乱和错误。因此,提出来加以讨论,澄清这种混乱和错误,是完全有必要的。 A black Liu ■ Sui is a peasant uprising in the succession ■ Jiande rebellion of the important peasant leaders. He had played a huge role in cracking down on the feudal rule of the time, especially the Tang regime, forcing him to give way to the peasants.

Moreover, this incorrect conclusion inevitably involves the total evaluation of the general issue of “the reunification war,” causing confusion and mistakes. Therefore, it is totally necessary to raise the issue for discussion and clarify such confusion and error.
