“通俗历史热”是商品经济和文化教育发展到一定程度后定会出现的一种现象。实际上通俗历史并非“新生事物”，它以讲说形式流传的历史已经相当久远了。一般情况下，这种历史的口头讲说是以十分平静的方式存在于民众的日常生活之中的，很少“走热”。但是，当商品经济趋于发达、文化教育发展迅速的时候，人们在从事赖以谋生的职业活动之外，带有文化色彩的业余需求会随之增长，对作为文化存在常见形态之一的历史知识，其“求解”欲望趋于强烈，那些久远的尘封旧事引起了人们日益浓厚的兴趣。这使通俗历史在当下有了“升温”的沃土，其“历史的惯性”开始充分显现出来。客观地说，对于广大民众而言，在古奥难懂的传统史著和“学术模式”的现代史书皆难“卒读”的情况下，通俗化的历史几乎成为他们“探寻过去”的唯一选择。
