Relations with Charlemagne

When the report of the Second Council of Nicaea (in 787 CE) was written up approving the use of icons for religious purposes, it mentioned the firm agreement between the pope in Rome and the emperor of Constantinople. As a document that would be made public to let everyone know the outcome of deliberation, it was going to upset at last one person: a powerful person with strong religious views who felt he deserved the pope's respect.

Before we go on to try to explain the controversy involved, let's explain the map you see here. The orange sections are the Byzantine Empire, which include Rome (and Sicily, Sardinia, and Corsica), since the Byzantines had effectively been the guardians of the Roman Empire. The rest of the areas were controlled by Lombards.

Let's try to spell this out. Charlemagne was the king of the Franks. There was a Frankish presence in Lombard-controlled northern Italy (Lombardy), having driven out Desiderius and his son Adalgis in 774. Constantinople wanted to restore Adalgis to the throne, and so they started an expedition to Italy to try to regain Lombardy from the Franks. This, of course, put them at odds with Charlemagne. The pope wanted an alliance with Charlemagne, as the closest strong ruler and a good person to have on your side.

It gets a little more twisted when we find out that Adalgis, hanging out in Pavia after being ousted from Lombardy, hosted the widow and children of Carloman I, Charlemagne's younger brother who had been forced to renounce the throne and go to a monastery. Even more twisted is the fact that Desiderius had been Charlemagne's father-in-law by virtue of his daughter Desiderata's marriage to Charlemagne (who had divorced her in 771).

The proceeds of the Council did not mention Charlemagne at all as being important to the adoption of the new policy among the Christian world. This was a public embarrassment for the pope, and things got worse when the Byzantines came to Italy to free Lombardy.

One of the other reasons for the attempt to drive the ranks out of Lombardy was the breakdown of negotiations for a royal marriage: Charlemagne's daughter Rotrude to Constantine VI, the seven-year-old emperor still in the regency of Empress Irene.

That's a lot to digest. Let's look at the actual fighting tomorrow and see who won.
