Critical edition of the charters of emperor Louis the Pious (+840): Systematic revision of the manuscript before starting printing

虔诚者路易皇帝（+840年）特许状的第一个关键版本，他是最后一个统治整个法兰克帝国的人。在他的统治下，许多领域的发展成长起来，原来是对未来的重要。对于这些发展，皇家宪章是非常重要的来源，而且往往标志着历史解释的局限性。作为12世纪末MGH系列皇家宪章的最后一个空白，所有历时研究迄今为止都因缺乏这一关键版本而受到阻碍。

First critical edition of the charters of emperor Louis the Pious (+840) who was the last to reign over the entire Frankish Empire. During his reign a lot of developments on many fields grew up which turned out to be significant for the future. For these developments the royal charters are very important sources, and often mark the limits of historical interpretation. Being the last gap within the MGH series of royal charters up to the end of the 12th century, all diachronic studies were so far handicapped by the lack of this critical edition.
