The Sikh gurus adopted proto-Gurmukhī to write the Guru Granth Sahib, the religious scriptures of the Sikhs. The Takri alphabet developed through the "Devāśeṣa" stage of the Sharada script from the 14th-18th centuries and is found mainly in the Hill States such as Chamba, Himachal Pradesh and surrounding areas, where it is called "Chambyali". In Jammu Division, it developed into Dogri, which was a "highly imperfect" script later consciously influenced in part by Gurmukhi during the late 19th century, possibly to provide it an air of authority by having it resemble scripts already established in official and literary capacities, though not displacing Takri. The local Takri variants got the status of official scripts in some of the Punjab Hill States, and were used for both administrative and literary purposes until the 19th century. After 1948, when Himachal Pradesh was established as an administrative unit, the local "Takri" variants were replaced by Devanagari.
