Yassa

TheYassa(alternativelyYasa,Yasaq,JazagorZasag;Mongolian:Их Засаг,romanized:Ikh Zasag) was the oral law code of the Mongols, gradually built up through the reign ofGenghis Khan. It was thede factolaw of theMongol Empire, even though the "law" was kept secret and never made public. The Yassa seems to have its origin in wartime decrees, which were later codified and expanded to include cultural and lifestyle conventions. By keeping the Yassa secret, the decrees could be modified and used selectively. It is believed that the Yassa was supervised by Genghis Khan himself and his adopted sonShigi Qutuqu, then the high judge (in Mongolian:улсын их заргач) of theMongol Empire.Genghis Khan appointed his second son, Chagatai (laterChagatai Khan), to oversee the laws' execution.
The wordyasa(orYassa) exists in both Mongolic and Turkic languages. It is believed that the word derives from theProto-Mongolianverb *jasa-(ModernMongolian:засах,romanized:zasakh), which means "to set in order".The Turkic verbyasa-, which means "to govern; to create", was probably borrowed from Mongolian.
In the earliest text in Mongolian,the Secret History of the Mongols, the wordyassaseems to refer specifically to authoritative (military) decrees.Čerig žasa-(Middle Mongolian:扯里克᠌札撒) - roughly equivalent to modern Mongolian:цэрэг засах- is a phrase commonly found in theSecret Historythat means "to set the soldiers in order", in the sense of rallying the soldiers before a battle. In modern Mongolian, the verbzasaglakh(засаглах) means "to govern".
Another word, which is sometimes equated withyassa, isyosun(ModernMongolian:ёс,romanized:jos). This term refers, broadly, to rules deriving from tradition, including for example rules of etiquette. Early chroniclers from Europe and the Middle East oftentimes did not clearly distinguish between the two terms - sometimes for ideological reasons - resulting in sources that often contain a mixture of laws and customs.
Jasaghduring theQing dynastyreferred to native provincial governors in Mongolia. The local office (theLifan Yuan) served as their court of the first instance, and included secretaries and other officials.
The supreme executive body of the present-day Mongolian government is called theZasgiin gazar (Mongolian:засгийн газар), which means "the place ofZasag", i.e. "the place of order".
According to some scholars, the Yassa was proclaimed by Genghis Khan atthe kurultai of 1206,when he officially assumed the title of Genghis Khan. In theSecret History, Genghis Khan tells his adopted son Shigi Qutuqu to create a register of jurisprudence, which implies the existence of such a document:
The Yassa may have later been written down in theUyghur script, preserved in secret archives and known only to and read only by the royal family.Juvyani, in theTarikh-i Jahangushay, writes of the role of theyasasduring akurultai(a military council):
The Yasa decrees were thought to be comprehensive and specific, but no Mongolian scroll or codex has been found. There are records of excerpts among many chronicles including those ofal-Maqrizi,Vardan Areveltsi, andIbn Battuta. The first of these may have relied on the work of Ata-Malik Juvayni, anIlkhanateofficial.Moreover, copies may have been discovered in Korea as well.
In the end, the absence of any physical document is historically problematic.Historians are left with secondary sources, conjecture and speculation, which describe much of the content of the overview. Historical certainty about the Yassa is weak compared to the much olderCode of Hammurabi(18th century BCE) or theEdicts of Ashoka(3rd century BCE). The latter was carved for all to see on stone plinths, 12 to 15 m high, which were located throughout Ashoka's empire (now India, Nepal, Pakistan and Afghanistan).
Ögedei Khan, the third son of Genghis Khan and the second Great Khan, proclaimed the Great Yassa as an integral body of precedents at his coronation atthe kurultai of 1229.He confirmed the continuing validity of his father's commands and ordinances, and added his own. Ögedei codified rules of dress, as well as the conduct of the kurultais. His two immediate successors followed the tradition of proclaiming the Yassa at their coronation.
The Mongols who lived in various parts of the empire began to add laws that were needed in their areas.
In the modernTurkish language(as used presently inTurkey), the word for "law" isyasa, and the adjective "legal" isyasal. The word for aconstitution, including theConstitution of Turkey, isAnayasa("mother-law").
The contents of the Yassa are not known from one single document, but scholars have reconstructed their contents from numerous sources relating to them. Among these, of particular interest are of course theSecret History, but also theTarikh-i Jahangushayof Juvyani, and other works by contemporaries. Most detailed non-Mongolian sources don't distinguish clearly between legal decrees (yassa) and customs (yosun).
In theSecret History, Genghis Khan tells Shigi Qutuqu, his adopted son, to create a blue-script book, which may be one of the books that formed the basis for what was later understood as the Yassa. In this book, as Genghis tells Shigi Qutuqu, the following items should be collected:
According to David Morgan, this amounts to: (1) "Matters pertaining to [the] division (...) of spoils and property"; and (2) "Matters pertaining to trials".Elsewhere in theSecret History, individual decrees of Genghis Khan are mentioned, but to what extent these should be understood as permanent laws is not always clear.
In theTarikh-i Jahangushay, a work by the Ilkhanate official Ata-Malik Juvyani, there appears one chapter dedicated to commenting on theyassas.This chapter is by no means comprehensive, as stated by the author himself:
However, some of the organisational matters discussed by Juvyani match pretty well with the brief statement in theSecret Historyabout the contents of Shigi Qutuqu's blue-script book. He mentions both matters of tax, provisions and the divvying up of spoils, as well punishable offences, most of which appear to apply specifically to the peasantry that made up the army.
On the one hand, for example, he states that there is a requirement toshare food with travelers, a rule of selling women from other families, and a duty to maintain provisions for theǰamči's (post stations). On the other hand, he paints a picture of strict army dicipline, mentioning a ban ondefectionfor soldiers, with the alleged punishment being summary public execution of the defector, and severe punishment for whoever offers shelter to the defector.
Throughout the rest of the work, Juvyani also mentions individualyassas, sometimes specifically ascribing them to Genghis Khan or his successors, and sometimes without further specification.
The exoteric aspect of Yassa outlined laws for various members of the Mongol community such as soldiers, officers and doctors. The Yassa aimed at three things: obedience to Genghis Khan, a binding together of the nomad clans and the merciless punishment of wrongdoing. It concerned itself with people, not property. Unless a man confessed, he was not judged guilty.The purpose of many decrees was probably to eliminate social and economic disputes among the Mongols and future allied peoples. Among the rules were the ban oncattle raiding. It represented a day-to-day set of rules for people underMongolcontrol that was strictly enforced.
The Yassa also addressed and reflected Mongol cultural and lifestyle norms. Death via decapitation was the most common punishment unless the offender was of noble blood, when the offender would be killed by way of back-breaking, without shedding blood. Even minor offences were punishable by death. For example, a soldier would be put to death if he did not pick up something that fell from the person in front of him. Those favored by the Khan were often given preferential treatment within the system of law and were allowed several chances before they were punished.
As Genghis Khan had set up an institution that ensured complete religious freedom, people under his rule were free to worship as they pleased if the laws of the Yassa were observed.
