Trade is one way that gunpowder was transmitted across Asia to
Europe. There is another factor that played a significant role in the history of
gunpowder's movement. The nomadic lifestyle was one of constant travel. Nomads
did not, for the most part, settle in one location and farm the lands. Instead,
they travelled across vast portions of the grasslands of northern Asia and
Europe, known as the steppes. Nomads had three major methods of survival in this
harsh habitat. Much of their meat and clothing came from the herds of livestock
that they raised on the steppes. Items they could not produce on their
own, such as metal objects, they traded for with settled cultures. If this was
unsucessful, then the nomads would often resort to violent methods. The nomads
made their influence felt all across the world. It is this influence and the
lifestyle of the nomadic people that have helped transmit gunpowder across the
world.
The Mongol people were a nomadic group that lived on the steppes above northern China. From the early days of the Chinese empire, these nomadic warriors were a constant threat. What they could not produce on their own from herds of livestock or from trade with settled people, they would steal. In order to remain on a level equal to the growing Chinese empire, the Mongols captured Chinese technicians and forced them to reveal their secrets. This was necessary to maintain an advantage over the Chinese. Without this advantage, the Mongols would not have any backing for their threats and would not be able to successfully raid when necessity demanded it. With these technicians, the Mongols acquired the technologies being developed in China. The Mongols learned about gunpowder relatively soon after it became common place in China Proper. There are other ways in which the Mongols would have been exposed to gunpowder. As they attacked Chinese towns, they were attacked by Chinese soldiers with fire-lances and explosive bombs.
But the [Chinese]ships had on board a supply of those bombs called thundercrash missles and they hurled these at the enemy. Flashes and flames could distinctly be seen ... eventually the [Chinese] fleet broke through, and safely reached Tung-kuan.
The Mongols, under Genghis Khan, were successful in taking the
capital and defeating the Chinese. Under Kublai Khan, grandson of Genghis, the
Mongols were successful in conquering the Sung Dynasty in southern China. The
Mongols now had complete control over China. With control of China, they would
also have had control over Chinese gunpowder research. Successfully conquering
all of China was not enough for the Mongol rulers, however. They wanted to
expand their empire west into Central Asia. The expansion of the Mongol regime,
and the states that they set up, helped to transmit gunpowder west into Central
Asia.

The Expansion of the Mongol Regime
At the height of the Mongol regime, the empire had expanded almost to the Mediterranean coast and as far as the Russian states in eastern Europe. This was the situation of the empire at the time of Kublai Khan's death. He had successfully campaigned into Central Asia and eastern Europe. The empire at his death was divided into multiple states ruled by Mongol lords. These states included the Golden Horde in Russia, the Ilkhan Empire in Iran, and the Empire of Jagatai in Central Asia, not to mention the central hub of Mongol rule in China. The map above illustrates the size of the empire. The area outlined in dark red is the extent of the Mongol Empire at the death of Kublai Khan. With the empire stretched so far into Central Asia, interaction with pre-existing cultures was a given. The Islamic people would have had considerable contact with the Mongol invaders. Many Mongols converted to Islam during this time. As a result, many Mongols would have remained behind as the rest of the army moved on. It is possible that some of these Mongols were technicians skilled in the production of gunpowder. Therefore, they would have introduced gunpowder into Muslim society rather quickly.

The Rise of the Ottoman Empire
A group of nomads that lived in the Middle East, known as the
Turks, began to form small states during the chaos following the Mongol capture
of Baghdad in 1258. The Turks, descendents of earlier Mongol nomads, eventually
built up a sizeable force. Interaction with Mongol warriors would likely have
given the Turks knowledge of gunpowder. This would have given the Turks, under
the rule of a small group of men known as the Ottomans, a clear advantage. With
the destruction of the Byzantine city of Constantanople in 1453, the Ottomans
created their empire. Under the rule of Suleiman the I, the Ottoman Empire
expanded into Europe. The print at the right shows the prominance of artillery
in his campaigns. Suleiman used gunpowder heavily to bring about the expansion
of the Ottoman empire in the 1500s. It is very possible that Suleiman could have
helped to bring the cannon into mainstream uses in Europe because of his
extensive campaigns there. In any event, gunpowder made a large impact on the
Middle East when it was brought by the Mongol
invaders.
The Moguls Conquer India
The Moguls were a group of nomads from the Hindu Kush mountain
range in Central Asia. In 1526, Babur, a descendant of Genghis Khan and of the
nomadic leader Tamerlane, led armies down from the city of Kabul in the Hindu
Kush mountains and succesfully defeated an army led by the sultan of Delhi that
was four times the size. Babur was victorious because he successfully used
gunpowder that he had brought with him. Being a descendant of the illustrious
Mongol leader, Babur himself was a Mongol in his own right. This would have
given him access to Mongol technology, such as gunpowder. When he conquered the
sultan, he set up his empire in India. This empire was known as the Mogul
empire, Mogul being another name for Mongol. Babur died in 1540, and his son
inherited the empire. Baburs son was not the leader he was, and he was defeated
many times by his enemies. In one account, an Afghan chief forced Baburs son to
flee from battle by not allowing him to use his artillery. When Baburs son fled,
it is likely that his artillery was confiscated by the Shah. This could have
helped spread gunpowder into Central Asia. The rise of Baburs grandson Akbar
brought about a return of power to the Moguls. The Moguls took back the
territory that they had lost and helped India flourish. None of Akbars triumuphs
would have been possible without the use of artillery. The influence of Moguls
on Indian life would have helped to strengthen the presence of gunpowder in
India. Chinese traders would have begun the process hundreds of years before,
and there is evidence of this in early Indian texts. The Moguls, however, helped
bring gunpowder to fruition in India, having received it from Mongol nomads
years
before.
Marco Polo and his Journey to China
The Mongol expansion throughout Asia and into Europe was one cause
for the migration of gunpowder. However, European explorers also traveled from
Europe to China. The most noteable of these explorers were the Polo's, Niccolo, Maffeo, and of course, Marco. These
Venetians traveled to Mongol China in the later part of the 1200s. When the
Polos arrived in China, they were greeted at the court of Kublai Khan, leader
of the Empire of the Great Khan. Their journey is one example of many journeys
that Europeans took during this time period. The significance of these trips
in the transmission of gunpowder could be significant. The Mongols were very
proficient with the techonology of gunpowder. Travelers, like the Polo's, were
exposed to many of the marvels of Chinese invention. When they left, they took
back many Chinese products. One product that may have returned with them was
gunpowder, or a recipe for gunpowder. When they returned to Europe, this recipe
would have been spread throughout Europe by word of mouth or in books written
by the travelers. This could explain how Roger Bacon knew about gunpowder around
this time.
