Final

Events

The Fall of Rome

476

The Western Empire falls to Germanic tribes while the Eastern Empire remains. The easterners begin to view the West as a bunch of ignorant, uneducated barbarians.

First Schism

484

Acacius, the Bishop of Constantinople, persuades Eastern Emperor Zeno to issue the Henoticon (“Act of Union”) to appease the Monophysites --a doctrinal compromise and a contradiction of Chalcedon, which all the Eastern bishops sign. Pope Felix III excommunicates both Acacius as well as the Patriarchs of Alexandria and Antioch --in essence, excommunicating the entire East!

New Language

500

Latin becomes the official language of the Eastern Empire.

First Schism Healed

526

When Pope John I travels to Constantinople and obtains a profession of
orthodox faith from Emperor Justin I --a significant achievement considering

Byzantines as the “successor of Peter,” and is called upon to re-crown
Justin as emperor.

Crowning of Justinian

Justinian I is crowned emperor.

Building of the Hagia Sopia

The Second Schism

654

In a desperate attempt to re-unify his Christian Empire and
bring the dissident Christians of Egypt, Palestine, and Syria back into the
fold, Emperor Constans II tries to impose the doctrine of Monothelitism on the Empire as a compromise with Monophysitism. The heresy is rejected by the West, but temporarily embraced by the Maronite church in Syria and Lebanon.

The Pope Arrested

655

After condemning the heresy of Monothelitism at a synod held in Rome, Pope Martin I is arrested by Byzantine troops and taken to Constantinople, where he is publicly abused by the mob and then exiled to Crimea, dying for orthodoxy.

Carthage Retaken

The Crowning of Charles the Great

800

Pope Leo III crowns Charlemagne Emperor of the West (A.K.A. Holy Roman Emperor). This act marks the end of Papal dependence on the Eastern Emperor, but the Pope refuses Charlemagne’s pressure to include the “Filioque clause” in the Nicene Creed, so as not to alienate the East.

Charlemagne Dies

814

Charles the Great passes away on January 28, 814 at the age of 72 due to natural causes.

Byzantine Alliance

859

Boris I withdraws his acceptance of the primacy of Rome when Pope Adrian II refuses to make Bulgaria a patriarchate. Bulgaria shifts its allegiance to Constantinople -- a Byzantine political coup, since Constantinople needed to “control” the Bulgarians to protect their northern frontier.

Conversions

865

The Byzantine court sends Sts. Cyril and Methodius into the Balkans to convert the pagan Slavs. Though originally part of the Eastern Empire, this region falls into the Pope of
Rome’s Western patriarchate; and Roman Rite missionaries from Germany conflict
with the Byzantines, who are adapting the Liturgy into Slavonic, and thus
achieving more conversions. To get to the bottom of this conflict, the Pope
calls Cyril and Methodius to Rome; and Rome gives its blessing to their
ministry. Cyril and Methodius also recognize the universal primacy of the
Pope of Rome. Thus, the Slavic Balkan kingdoms embrace the Byzantine Rite as
opposed to the Roman Rite --another coup for the court of Constantinople
which, as with Bulgaria, needed to establish religious /cultural ties with
the Slavs so as to safeguard the Empire’s northern frontier.

The Fourth Schism

Anti-Latin Campaign

Michael Cerularius, Patriarch of Constantinople, launches an anti-Latin campaign.
