Ère Saka

The Shaka era (IAST: Śaka, Śāka) is a historical Hindu calendar era (year numbering), the epoch (its year zero) of which corresponds to Julian year 78. The era has been widely used in different regions of the Indian subcontinent as well as in Southeast Asia. According to the Government of India, it is referred as the Shalivahana Era (IAST: Śālivāhana). The origin of the Shaka era is highly controversial. There are two Shaka era systems in scholarly use, one is called Old Shaka Era, whose epoch is uncertain, probably sometime in the 1st millennium BCE because ancient Buddhist and Jaina inscriptions and texts use it, but this is a subject of dispute among scholars. The other is called Saka Era of 78 CE, or simply Saka Era, a system that is common in epigraphic evidence from southern India. A parallel northern India system is the Vikrama Era, which is used by the Vikrami calendar linked to Vikramaditya. The beginning of the Shaka era is now widely equated to the ascension of Indo-Scythian king Chashtana in 78 CE. His inscriptions, dated to the years 11 and 52, have been found at Andhau in Kutch region. These years are interpreted as Shaka years 11 (89 CE) and 52 (130 CE). A previously more common view was that the beginning of the Shaka era corresponds to the ascension of Kanishka I in 78 CE. However, the latest research by Henry Falk indicated that Kanishka ascended the throne in 127 CE. Moreover, Kanishka was not a Shaka, but a Kushana ruler. Other historical candidates have included rulers such as Vima Kadphises, Vonones, and Nahapana. According to historian Dineshchandra Sircar, the historically inaccurate notion of "Shalivahana era" appears to be based on the victory of the Satavahana ruler Gautamiputra Satakarni over some Shaka (Western Kshatrapa) kings. Sircar also suggested that the association of the northern king Vikramaditya with Vikrama era might have led the southern scholars to fabricate a similar legend. Another similar account claims that the emperor Shalivahana, grandson of legendary emperor Vikramaditya defeated the Shakas in 78 CE, and the Shaka era marks the day of this conquest.
