Anglo-Saxon military organization is difficult to analyze because there are many conflicting records and opinions as to the precise occurrences and procedures. Anglo-Saxon England was known for its tumultuous nature and the constant presence of outside threats and dangers made it necessary for a solid military to be constantly in place. However, in spite of this, by the 10th century the Saxon kingdom of England was, perhaps, the best ordered state in Europe with a highly efficient administration that had a solid currency and could raise taxes to support a military establishment. Even though there is some controversy as to the accurate forms of military organization, some aspects can be deduced from the records that have been preserved.
