Ror dynasty
The Ror dynasty was a power from the Indian subcontinent that ruled modern-day Sindh and northwest India from 450 BC. The Rors ruled from Rori Shankar and was built by Raja Dhaj in the 5th century BCE. Rori Shankar has been known by names such as Roruka and Rorik since antiquity. As capital of the Sauvira Kingdom, Roruka is mentioned as an important trading center in early Buddhist literature. Buddhist Jataka stories talk about exchanges of gifts between King Rudrayan of Roruka and King Bimbisara of Magadha. Divyavadana, the Buddhist chronicle has said that Roruka historically competed with Pataliputra in terms of political influence.
Shortly after the reign of Rudrayan, in the times of his son Shikhandi, Roruka got wiped out in a major sand storm. This event is recorded in both Buddhist and Jain annals. It was then that the legendary Raja Dhaj built Rori Shankar in the year 450 BC.
