查理曼个人的征战是西欧中世纪早期历史的重要组成部分，而“萨克森战争”是其中最为重要的篇章之一。在这场历时33载的战争中，先后出现了三部针对萨克森地区的法律文本，它们分别为《萨克森地区条令》、《萨克森条令》与《萨克森法典》，这三份法令在后世学界的研究中被统称为《萨克森法令集》。前两份萨克森条令属于法兰克王国时期的特殊法律文件，具有国王行政命令的性质，而《萨克森法典》则是查理曼称帝后所主导的大规模法典编纂工作的产物。因而，《萨克森法令集》不仅能够反映出萨克森战争整体形势的演化，也能够反映查理曼个人的意志，是他对萨克森人所规划的征服政策的集中表现。

萨克森战争大体上可以分为772-785年和792-804年两个主要阶段。在第一个阶段中，查理曼对萨克森人的征服政策主要侧重于迫使萨克森人全面基督教化和在萨克森地区建立法兰克式秩序和体制。而第二个阶段中，查理曼的政策则是通过对萨克森人的大规模强制皈依和加剧萨克森社会的内部分化来瓦解他们最后的抵抗力量。

《萨克森地区条令》产生于战争的第一阶段，其条款主要关注于宗教和行政两个方面，表现了查理曼对于萨克森地区的基督教化和伯爵制度这两个具体事务的关注与要求。《萨克森条令》和《萨克森法典》都是产生于战争的第二阶段。前者主要关注司法问题，是对其他法令的修正、补充与辅助。而后者涉及到的问题较多，其中既有刑法条款，也有民法条款，是对于萨克森人社会方方面面问题的整体规范。

《萨克森法令集》在查理曼的萨克森政策扮演着重要的角色，主要体现在政治征服和基督教化两个方面。在政治征服方面，法令集在没有王权传统的萨克森地区试图树立起法兰克国王的权威，尝试将伯爵制度与萨克森人传统的司法习惯相结合，并且通过加强萨克森贵族的法律地位来加剧萨克森社会的等级分化，从而瓦解萨克森人的抵抗势力，全面巩固法兰克人的征服成果。在基督教化方面，法令集对萨克森人的异教习俗与传统进行打击，使用强硬的手段捍卫基督教信仰，并且加强教会的建设，给与教会与神职人员更多的保护和权力，从而推动萨克森人的基督教化。

总的来说，《萨克森法令集》反映了当时代政治、法律、宗教等多方面问题，整体上与萨克森战争的局势演化密切相关，并且在查理曼对萨克森人的征服政策中扮演着重要的角色。

Charlemagne's campaigns are a significant part of the early medieval history of Western Europe, among which the Saxon War is one of the most important chapters. In this 33-year war, three legal texts focused on the Saxon region, which are the Capitulatio de partibus Saxoniae, Capitulare Saxonicum, and Lex Saxonum. These three decrees were collectively referred to as the Leges Saxonum in the studies of the later generations of academics. The first two Saxon decrees are special legal documents of the Frankish period, with the nature of the king's executive orders, while the Lex Saxonum is the product of the large-scale codification work led by Charlemagne after his accession as the emperor. Thus, the Saxon Code not only reflects the evolution of the overall situation of the Saxon War, but also effectively reflects Charlemagne's will, and is the centralized expression of the conquest policy he planned for the Saxons.

The Saxon War can be roughly divided into two main phases: 772-785 and 792-804. In the first phase, Charlemagne's policy of conquest against the Saxons focused on forcing the Saxons to fully Christianize and establish a Frankish order and institutions in Saxony. In the second phase, Charlemagne's policy was to break down the last pockets of Saxon resistance through mass forced conversions of the Saxons and the intensification of internal divisions in Saxon society.

The Capitulatio de partibus Saxoniae, which arose in the first phase of the war, focused on both religious and administrative aspects and demonstrated Charlemagne's concern and demand for two specific matters: the Christianization of Saxony and the countship. The Capitulare Saxonicum and the Lex Saxonum were both produced in the second phase of the war. The former was mainly concerned with judicial matters, amending, supplementing and supplementing the other decrees. The latter, on the other hand, dealt with a wider range of issues, including both criminal and civil law provisions, and was an overall regulation of all aspects of Saxon society.

The Leges Saxonum played an important role in Charlemagne's Saxon policy, mainly in the areas of political conquest and Christianization. In terms of political conquest, the Leges attempted to establish the authority of the Frankish king in the Saxon region, where there was no tradition of kingship, tried to combine the count system with the traditional judicial customs of the Saxons, and intensified the hierarchical division of Saxon society by strengthening the legal status of the Saxon nobility, so as to break down the resistance of the Saxon people and consolidate the achievements of the Frankish conquests in a comprehensive way. In terms of Christianization, the Leges combated the pagan customs and traditions of the Saxons, defended the Christian faith by strong means, and strengthened the construction of the church, giving more protection and power to the church and the clergy, to promote the Christianization of the Saxons.

Overall, the Leges Saxonu, reflect the political, legal, and religious issues of the time, and as a whole, they are closely related to the evolution of the Saxon wars and played an important role in Charlemagne's conquest policy towards the Saxons.
