Yes there is in a certain sense, nothing really written down that I know of. BTW I edited the title for you True, more people will understand 'Code of the Samurai' than 'Code of the Samuri'
In five millennia, the Mandalorians fought with and against a thousand armies on a thousand worlds. They learned to speak as many languages and absorbed weapons technology and tactics from every war. And yet, despite the overwhelming influence of alien cultures, and the absence of a true home world and even species, their own language not only survived but changed little; their way of life and their philosophy remained untouched; and their ideals and sense of family, of identity of nation, were only strengthened. Armor is not what makes a Mandalorian. Armor is simply a manifestation of an impenetrable, unassaliable heart. "
Ã¢Â€Â” Passage from "Mandalorians: Identity and Language"
A Mandalorian weddingMandalorian culture consisted of a very straight-forward nomadic society, influenced by many other cultures around the galaxy. As a whole, Mandalorians were not prejudiced of any species, but tolerated all Mandalorians, as long as they followed Mandalorian principles. Many war-orphaned children (such as Jango Fett) would be adopted into Mandalorian society, and brought up as Mandalorian children.
Mandalorian women were expected to have the same combat skills as men, in order to defend their homes when the men were away. If they didn't have children to raise, they fought alongside men on the battlefield. The ideal Mandalorian woman was physically strong and resilient.
The Mandalorians were nomadic warriors, despite the fact that they had the home world of Mandalore. The Mandalorians kept their nomadic ways so that in the event of attack, there would be no easy target to exterminate the Mandalorians. This attributed to the Mandalorians' survival over thousands of centuries. This also meant that many Mandalorians had not ever visited Mandalore.
Individual Mandalorians were independent warriors, bound together by the same culture. Created by their own hands, fitted to their liking, each piece of Mandalorian steel was chosen and customized by a Mandalorian to their level of skill. The armor had great cultural significance for the Mandalorians, and each set told about the Mandalorian underneath. However, there was a saying in Mando'a: Verd ori'shya beskar'gam, meaning a warrior is more than his armor.
Not all Mandalorians constantly fought on the front line. There were farmers, regular factory workers, engineers, and doctors too. However, all Mandalorians were warriors at heart, and all knew how to fight.
Mandalorians were considered adults at an age as low as thirteen years. This contributed to the fact that Mandalorians married and settled down earlier than most cultures. Family bonds were a large part of the Mandalorian culture, and as a result, they felt more comfortable around each other than they did around strangers. Mandalorian weddings were brief, and meant serious commitment to each other.
A Mandalorian teaches his sonThere were six acts one needed to follow to be a Mandalorian, those being wearing armor, speaking Mando'a, defending theirselves and families, raising children as Mandalorians, helping the clan succeed and sustain itself, and when called to arms by the Mandalore, rally to his cause.
The only leader of the Mandalorians was the Mandalore himself, and he held his rank as long as he commanded the respect of his fellow warriors. In battle, Mandalorians would be assigned to different squads and jobs, depending on their area of expertise. The Mandalorians worked together to the best of their ability in battle. Mandalorians were not promoted to better jobs, since they did not have jobsÃ¢Â€Â”only in battle would some kind of organization need to occur.
The only exception to this would be the way Jaster Mereel ran the Mandalorians. He often diverted from the culture of the Mandalorians, but only slightly so. His armor was different from everybody else's, which was gold and red, perhaps signifying rank. His second in command, Montross, wore silver and blue armor. This armor-rank system was carried on by Jango Fett, who wore Jaster's armor, and had his second in command, Myles, wear the blue-silver armor. Like Jaster, Jango did not act like a traditional Mandalorian.
Mandalorians had their own religion, the basic tenets of which have fluctuated over the centuries. At one time, Mandalorians were deeply religious beings, but the combination of disillusion with the old ways and the increasing warlike tendencies of the race led to a more pragmatistic view of the galaxy around them. Creation tales such as the Akaanati'kar'oya (The War of Life and Death) became more philosophical, while the stars became the fallen kings of Mandalore. More skeptical Mandalorians, however, often looked at such tales for allegories that could be applied to the here and now.
To Mandalorians, the afterlife is seen as a place of conflict between stagnaton and change, mythicized by the gods Arasuum (a sloth like being that personifies idle consumption) and Kad Ha'rangir (seen as a vicious destroyer that forces change on the universe). It is said that Mandalorians who die become part of the armies of these two gods, defending the one true place where their wives, sons and daughters may finally find a permanent place of rest.
Family is very important to the Mandalorians, yet when compared to most other cultures, they hold very different beliefs to what constitutes a familial relationship. Despite the fact that fidelity and chastity before marriage is highly emphasized, they are unconcerned about parentage. Believing that aliit iru'shya tal'din (Family is More Than Bloodlines), it is common for orphaned children, and even adults, to be brought into the culture. Marital infidelity, often considered a major faux pas in most other cultures, is not looked down upon during periods where two Mandalorians undergo a long term separation, so long as any children that arise from such an act are raised in the ways of Mando.
Despite their rather gruff appearance and style of combat, the average Mandalorian is more socialble and kind than one would expect. As long as individuals speak their mind, accept a meal when offered, look them straight in the eye (or the horizontal section of their visor), take off their boots while in their home, pay their debts, fuss over their children, never make a pass at Mandalorian of the opposite sex (unless the individual plans to become part of the culture) and treat their elderly with respect, anyone who encounters a Mandalorian is not likely to end up on the business end of a blaster or vibroblade
