Final answer:
The Catholic Church does not acknowledge Charlemagne as a saint because he lived before the canonization process was established and there are no documented miracles associated with him. However, he is still highly revered for his contributions to Christianity and Western civilization.
Step-by-step explanation:
The Catholic Church does not officially recognize Charlemagne as a saint primarily because he lived before the formal canonization process was established. Charlemagne died in 814 AD, while the canonization process as we understand it today was not developed until the 12th century. Therefore, he was never officially declared a saint by the Catholic Church.
Additionally, the process of sainthood requires evidence of miracles attributed to the individual after their death. While Charlemagne was a great ruler and had a significant impact on European history, there aren't any documented miracles associated with him that would meet the criteria for sainthood.
It's important to note that Charlemagne is still highly revered and recognized for his contributions to Christianity and Western civilization, but he is not officially recognized as a saint by the Catholic Church.
