<P> The Mongols sought alliances with other nations and societies to ensure the flow of trade through the empire . The Mongol army was also used to reshape and streamline the flow of trade through the continent by destroying cities on the less - important or more inaccessible routes . The Mongol military was mostly made up of cavalrymen . This allowed the military to move swiftly and easily over large distances . </P> <P> The code of Mongol law, known as the Yassa ("Great Law"), decreed strict rules and punishments in many areas of the Mongolian Empire's society, especially those areas concerning trade and commerce . The Yassa helped suppress the traditional causes of tribal feuding and war, thus helping to ensure a peaceful trading and travelling environment; theft and animal rustling were outlawed, and the Mongol Empire under Genghis Khan even established a massive lost - and - found system . Harsh penalties including a retribution of nine times the original value of stolen goods helped deter theft on Mongol roads . The Yassa also decreed complete religious freedom, ensuring that Buddhists, Muslims, Christians, etc., were all allowed to travel freely throughout the empire; religious leaders were also exempted from taxation, as were doctors, lawyers, undertakers, teachers, and scholars . The Yassa did allow for flexibility and it usually adapted, absorbed, or built upon legal systems in remote parts of the empire, thus maintaining a level of openness to various societies and ensuring peace and stability . </P> <P> In order to ensure Mongol law was enforced, a hierarchy of legal administration was developed . This was headed by the Secretarial Council "chug - shu - sheng" of the central government which oversaw 10 provincial governments known as "Hsing - sheng". The Hsinsing - sheng was further split into smaller districts which handled legal cases . A police commissioner known as "hsien wei" was entrusted with law enforcement and had the authority to arrest suspects . This method of federalising the empire made it easier and more efficient for laws to be administered throughout the continent . </P> <P> The Mongols established the Yam (Mongolian: Өртөө, Örtöö, checkpoint), the first system of communication that connected the Far East and the West . Relay stations were set up every 25--30 miles or an average day's journey on horse . These stations were introduced by Ögedei Khan in 1234 and supplied fresh horses and fodder . His brothers Chagatai Khan and Tolui and his nephew Batu Khan further extended this network . </P>
