Spread of rocket technology

Rocket technology first became known to Europeans following their use
by the Mongols Genghis Khan and Ögedei Khan when they conquered
Russia, Eastern Europe, and parts of Central Europe, i.e., Austria.
The Mongolians had stolen the Chinese technology by conquest of the
northern part of China and also by the subsequent employment of
Chinese rocketry experts as mercenaries for the Mongol military.
Reports of the Battle of Sejo in the year 1241 describe the use of
rocket-like weapons by the Mongols against the Magyars. [1]

Additionally, the spread of rockets into Europe was also influenced by
the Ottomans at the siege of Constantinople in 1453, although it is
very likely that the Ottomans themselves were influenced by the Mongol
invasions of the previous few centuries. They appear in literature
describing the capture of Baghdad in 1258 by the Mongols.[1]
