In 2018, medieval scholar Michael McCormick nominated 536 as "the worst year to be alive" because of the volcanic winter of 536 caused by a volcanic eruption early in the year, causing average temperatures in Europe and China to decline and resulting in crop failures and famine for well over a year.[1][2]
November – Siege of Naples: Belisarius captures Naples after a month's siege, by sending troops into the city through an abandoned Roman aqueduct.[4]
December 9 – Belisarius enters Rome through the Porta Asinaria, and the Gothic garrison of 4,000 men flees the city. He sends an urgent request for reinforcements to Justinian I, meanwhile preparing Rome for a siege, by bringing in great quantities of food and other supplies.[5]
Winter – Belisarius sets up his headquarters on the Pincian Hill, and repairs the neglected city walls of Rome. He stations a 5,000-man garrison, of whom half are his personal bodyguard (bucellarii). To hold parts of the city, he recruits 20,000 young Romans to man the walls.
Summer – Constantinianus, magister militum per Illyricum, retakes Dalmatia. The Goths abandon Salona and withdraw to the north. The Byzantines rebuild its walls and reclaim the province.[7]
December – Vitiges deposes his rival Theodahad at Ravenna, and marries Mataswintha (daughter of queen Amalasuintha). He becomes king of the Ostrogoths and assembles an army to fight against Belisarius.[4]
Africa
March–April – Belisarius sails to Carthage with 1,000 men, to suppress a mutiny against Solomon. Meanwhile, Carthage is besieged by 9,000 rebels, including many Vandals, under Stotzas.
The volcanic winter of 536, thought to have been caused by an extensive veil of dust in the atmosphere, began in the Northern Hemisphere. It continued until the following year, causing unseasonal weather and crop failure worldwide.[2]
