Buranjis (Ahom language: ancient writings) are a class of historical chronicles and manuscripts associated with the Ahom kingdom written initially in Ahom Language and later in Assamese language as well. The Buranjis are an example of historical literature which is rare in India; though they bear resemblance to Southeast Asian traditions of historical literature. The Buranjis are generally found in manuscript form (locally called puthi), though many of these manuscripts have been compiled and published. They are some of the primary sources of historical information of Assam's medieval past, especially from the 13th century to the colonial times in 1828. There were two types of Buranjis: the official Buranjis, which were compiled from the time of the first Ahom king Sukaphaa; and family Buranjis, which were compiled from the 16th century. The official Buranjis contained such information as description of important events as reported by reliable witnesses, correspondence from allied rulers, tax records, announcements, annual reports of various kinds, etc. Nevertheless, the Buranjis were continuously upgraded and often refreshed with the help of chronicles of allied peoples the Ahoms were in contact with, such as the Tai-Mau and Khamti. The official Buranjis were kept in archives and most of them have been destroyed either by natural decay or by wars and conflicts. The details in the Buranjis regarding the Ahom-Mughal conflicts agree with those in the Mughal chronicles such as Baharistan, Padshahnama, Alamgirnamah and Fathiyyah; and they also provide additional details not found in these Mughal chronicles. Description Buranji writing tradition There were two kinds of Buranjis: one maintained by the state (official) and the other maintained by families. Many such manuscripts were written by scribes under the office of the Likhakar Barua, which were based on state papers, such as diplomatic correspondences, spy reports, etc.<ref>"Information and facts mentioned in a buranji emerged after consulting state papers.... Official communications, letters of ambassadors or spy reports were significant parts of these state papers." </ref> The Buranjis and the state papers were usually secured in a store or library called Gandhia Bhoral under the supervision of an officer called Gandhia Barua. Others were written by nobles or by people under their supervision, often anonymously, though the authorship often becomes known. These documents reveal chronology of events, language, culture, society and the inner workings of the state machinery of the kingdom. They were written in "simple, lucid and unambiguous but expressive language with
