Mamluks & Mongols

[source]

The Mongols were expanding westward. Under Genghis Khan they had taken a huge chunk out of Asia, from what is now the Koreas, Mongolia, and Kazakhstan and the areas south of it, all the way to the Caspian Sea. Twenty years later, under Ögedei and Güyük and Möngke, they held most of what is now China in the east, and had extended into Ukraine and Belarus in the west and south to the Persian Gulf. Through conquering Turkey, they had control of the northeastern shores of the Mediterranean.

Mongol hordes were ruthless when taking over a new territory. Iran's resistance required such force to subdue that much of the country's agrarian infrastructure was destroyed, causing famine and serious population loss in the years following the wars.

The Mongol Empire had benefits, however, to others as well as itself: an enforced peace throughout this realm made travel and trade safe for foreigners as well as residents. Given time, they might have conquered—and therefore united—North Africa and Europe as well. For the first time in their history, however, they were stopped, defeated when they encountered the Mamluks.

Hulagu, a grandson of Genghis and brother to Kublai and Möngke, managed the southwestern front of the Mongol Empire, moving from Persia toward Egypt. He took down the Assassins, and conquered Baghdad by defeating the Abbasid Caliphate. He then sent a message to Qutuz in Cairo, advising him to submit to Mongol rule. Qutuz killed the messengers and stuck their heads on one of Cairo's gates.

Then word came that Möngke Khan had died, and Hulagu took much of his army back home to lobby for the throne. When Qutuz learned that a much smaller military force had been left behind in the Middle East, he gathered his Mamluk army and marched out of Cairo. Two armies of about 20,000 men each met on 3 September 1260 at Ain Jalut ["Spring of Goliath"] in Galilee.

The Mongol army did not know the territory as well as the Mamluks did (Qutuz had allied himself with a Mamluk leader from the region who knew it well and planned their strategy). The Mamluks played a "hit-and-run" game, then pretended to retreat, luring the Mongol army to follow them into the highlands where the largest part of the army was hidden, its archers waiting to ambush the Mongols. Although the Mongols rallied somewhat, they were unable to gain the upper hand. For the first time, their forward advance to expand their territory was stopped, placing a western border in the face of Genghis Khan's dream of a worldwide Mongol empire.

The Mamluks had another advantage: explosives, specifically hand cannons. Hand cannons were metal cylinders packed with gunpowder and set off with a flame. They were not good for aiming projectiles with any kind of accuracy, but in the Battle of Ain Jalut they were used to startle the opposing cavalry mounts and create confusion.

Fireworks

In honor of Independence Day in the USA...

Everyone knows that to discuss the history of fireworks means talking about China and Marco Polo (1254-1324), but the real history of fireworks in the European Middle Ages may start with Roger Bacon (1214-1294).

Bacon was a Franciscan Friar who spent time at Oxford and may have studied under Robert Grossteste. He has been called the first user of the scientific method, but more careful study of his works suggests that his conclusions and theories were the result of "thought experiments" like many other scholars, instead of actual scientific experimentation. Although Oxford's fairly careful and complete records of degrees given do not show that Bacon ever earned a doctorate, he was nicknamed Doctor Mirabilis (wonderful doctor) for his ideas.

Many volumes have been filled about Bacon, his ideas and discoveries, but today we are interested in gunpowder. At the request of Pope Clement IV, Bacon wrote his seven-part Opus Maius (Greater Work) which discussed (among other things) his thoughts on philosophy, theology, and certain scientific experiments. We know that a contemporary and fellow Franciscan, William Rubruck (c.1220-c.1293), visited the Mongols and witnessed the use of gunpowder in the form of firecrackers. Perhaps Rubruck brought some back. The relevant passage in the Opus Maius is:

We have an example of these things (that act on the senses) in that children's toy which is made in many [diverse] parts of the world; i.e. a device no bigger than one's thumb. From the violence of that salt called saltpetre [together with sulphur and willow charcoal, combined into a powder] so horrible a sound is made by the bursting of a thing so small, no more than a bit of parchment [containing it], that we find [the ear assaulted by a noise] exceeding the roar of strong thunder, and a flash brighter than the most brilliant lightning.

The "no more than a bit of parchment containing it" reminds me of these. He speaks of this again in his Opus Tertium (the Third Work; and yes, there had been an intermediate Opus Minus, the Lesser Work):

Then wonders can be done by explosive substances. There is one used for amusement in various parts of the world made of powder of saltpeter and sulphur and charcoal of hazelwood. For when a roll of parchment about the size of a finger is filled with this powder, it produces a startling noise and flash. If a large instrument were used, the noise and flash would be unbearable; if the instrument were made from solid material, the violence would be much greater.

These are the earliest references in the English-speaking world to gunpowder and fireworks. Whether Bacon ever made his own gunpowder is unknown, however. Some articles will tell you that he could, and encrypted the knowledge in order to prevent its misuse. Claims that Bacon hid the formula for gunpowder in his works cannot be substantiated, however. He seems to know what goes into the formula, but not necessarily in what proportion.  The secret numbers that some modern manuscript detectives claim to have found in his writings produce the wrong ratio for gunpowder to do more than smoke.

Enjoy your day.
