The Kanun is a set of traditional Albanian laws. The Kanun was primarily oral and only in the 20th century was it published in writing. There is only one Kanun since ancient times commonly referred to as the "Kanun of Leke", from which six later variations eventually evolved, categorized according to the area, the personality and their time of origin: Kanun i vjetër (English: Old Kanun), Kanuni i Lekë Dukagjinit (English: The Kanun of Lekë Dukagjini), Kanuni i Mirditës (English: The Kanun of Mirdita), Kanuni i Pukës (English: The Kanun of Pukë), Kanuni i Çermenikës (English: The Kanun of Çermenikë), Kanuni i Papa Zhulit (English: The Kanun of Pope Julius), Kanuni i Labërisë (English: The Kanun of Labëria) and Kanuni i Skenderbeut (English: Kanun of Skanderbeg) also known as Kanuni i Arbërisë (English: Kanun of Arbëria).
The Kanun of Skanderbeg is the closest in similarity with the Kanun of Lekë Dukagjini, and the latter is usually the most known and is also regarded as a synonym of the word kanun. The Kanun of Lekë Dukagjini was developed by Lekë Dukagjini, who codified the existing customary laws. It has been used mostly in northern and central Albania and surrounding areas formerly in Yugoslavia where there is a large ethnic Albanian population; Montenegro, Kosovo and Macedonia. It was first codified in the 15th century but the use of it has been outspread much earlier in time. It was used under that form until the 20th century, and revived recently after the fall of the communist regime in the early 1990s.
The term kanun comes from the Greek "κανών" ("canon"), meaning amongst others "pole" or "rule" and was transported from Greek to Arabic and then into early Turkish and then in Albanian. Kanun was also known by the word of Doke.
