A revolt against iconoclasm by the people…
729 CE
A revolt against iconoclasm by the people of the Exarchate of Ravenna results in Emperor Leo's dispatch of a fleet from Constantinople to capture the city.
The imperial fleet, partly wrecked in a storm along the way, is repulsed by a force of Italians, raised by Pope Gregory II in defense of image worship.
After a severe struggle, the Greeks are routed; thousands are killed in flight to their ships.
The waters of the Po River are so infected with blood, it is said, that for six years the inhabitants of Ravenna will not eat fish from the river.
The Exarchate becomes effectively detached from the Empire.
