Scientists and historians have concluded that the plague probably broke out around Lake Issyk Kul, in the country known today as Kyrgyzstan, before spreading east to China and west to the Middle East and Europe.

1320s - the period that plague broke out in Mongolia and the Gobi Desert, before starting to spread east and west, initially overland.

300 - the number of tribes wiped out by plague within a three month period, in what may have been Mongolia or northern China, as recounted by Arab chronicler Muhammad Al-Maqrizi (1363/4–1442).

120 million - the population of China in the 1330s.

90 million - the population of China in 1393.

Did You Know?

Some historians believe that a string of natural disasters in China in the 1330s – famine, floods, earthquakes, droughts - would have impacted not only the human population but the rodent population also. These rodents, within whom the plague bacillus was endemic, may then have migrated south into India and west into the area around Issyk Kul, taking the plague with them.

1338-39 - the years during which the plague broke out amongst communities living around Issyk Kul (the tenth largest lake in the world by volume, located in eastern Kyrgyzstan).

3 - the number of tombstones discovered near Issyk Kul that give the cause of death as plague.

"In the year of the hare. This is the grave of Kutluk. He died of the plague with his wife Magnu-Kelka memorial on the tombstone (the year of the hare is 1300).

1345 - the year in which the Black Death, following trade routes, reached Sarai, the capital of the Golden Horde, on the banks of the Volga river.

15 years - the period of time that the plague raged in the east before spreading to Europe, according to the Arab scholar Ibn al-Wardi. Having taken this long to reach the Crimea, spreading overland, the didease would now become waterborne, spreading via ships along trade routes into Europe. Now the Black Death would spread wider, farther and faster than before.

1346 - the year the plague reached and spread through cities along the coast of the Caspian sea, south into Astrakhan and Azerbaijan, and west to the Crimea, a major trading area of importance to Muslim and Christian merchants alike.

85,000 - the number of people said to have died from plague in the Crimea in 1346. The Christians were blamed for the deaths and were attacked at Tana before retreating to Caffa (or Kaffa, present-day Feodosiya in the Crimea) on the Black Sea coast. Here they came under siege from the Mongol/Tartar army, under the command of Janibeg.

1347 - the year the plague spread to Caffa. Towards the end of the siege, with Tartar troops were dying from plague in great numbers, Janibeg carried out a final act of revenge. In an early form of biological warfare, he had the bodies of plague victims catapulted over the walls into Caffa. Caffa's residents dumped bodies into the sea, but it was not enough to save the city, and the plague quickly spread

"What seemed like mountains of dead were thrown into the city [...] and soon the rotting corpses tainted the air and poisoned the water supply [...] one infected man could carry the poison to others, and infect people and places with the disease by look alone. Gabriele de Mussis (c. 1280 - c. 1356), describing the attack on Caffa.

Did You Know?

As the Genoese fled Caffa, heading out to sea, they unwittingly carried the disease with them, fleas having found their way into the cloth they carried or infesting the ships' rats. Sailing toward either Europe or the Middle East, every ship was a potential carrier of the disease.

1347 - the year in which the pestilence, spreading via the trade routes of the Mediterranean, reached the sea ports of Constantinople, Alexandria, and Cyprus. To the west, the ports of Messina, Genoa, Florence, Pisa and Venice were also struck. From these entry points the plague could now spread inland, carried via overland trading routes.

October 1347 - the month the plague arrived in Europe, at the Port of Messina in northern Sicily.

Did You Know?

The appearance of the plague in Italy in 1348 was seen by many as just another act of punishment by God. In 1309 the papacy had abandoned Rome and relocated to Avignon. More recently, earthquakes had recently struck in Rome, Pisa, Bologna, Padua, Venice and Naples. Prolonged rains in 1345 (incessant for six months) lead to food shortages in 1346 and 1347, as sowing became near impossible. Food costs soared, the economy fractured, and political infighting raged.
