From the 10th century onwards, regional differences started to appear between the Sharada script used in Punjab, the Hill States (partly Himachal Pradesh) and Kashmir. Sharada proper was eventually restricted to very limited ceremonial use in Kashmir, as it grew increasingly unsuitable for writing the Kashmiri language. With the last known inscription dating to 1204 C.E., the early 13th century marks a milestone in the development of Sharada. The regional variety in Punjab continued to evolve from this stage through the 14th century; during this period it starts to appear in forms closely resembling Gurmukhī and other Landa scripts. By the 15th century, Sharada had evolved so considerably that epigraphists denote the script at this point by a special name, "Devāśeṣa". Tarlochan Singh Bedi (1999) prefers the name "Pritham Gurmukhī", or Proto-Gurmukhī.
