Year 770 (DCCLXX) was a common year starting on Monday (link will display the full calendar) of the Julian calendar. The denomination 770 for this year has been used since the early medieval period, when the Anno Domini calendar era became the prevalent method in Europe for naming years.

Events

King Charlemagne signs a peace treaty with Duke Tassilo III of Bavaria, and marries the Lombard princess Desiderata (daughter of King Desiderius). He travels to the Lombard court at Pavia to conclude arrangements. Pope Stephen III opposes the marriage, and protests about a Frankish-Lombard alliance.^[1]
Hedeby, an important trading settlement, in the Danish-northern German borderland is founded (approximate date).

King Alhred of Northumbria takes an interest in continental missionary activities, and sends Willehad to Frisia in modern-day Netherlands (approximate date).

Caliph al-Mansur orders the closing of the Canal of the Pharaohs (Egypt). The only remaining land routes to transship camel caravans' goods are from Alexandria to ports on the Red Sea, or the northern Byzantine termini of the Silk Road.
