The Ror dynasty (Sindhi: روهڙا راڄ) was a power from the Indian subcontinent that ruled modern-day Sindh and northwest India from 450 BC. The Rors ruled from Rori and was built by Dhaj, Ror Kumar, a Ror Kshatriya, in the 5th century BCE. Rori 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 Ror historically competed with Pataliputra in terms of political influence. The scholar T.W. Rhys Davids has mentioned Roruka as one of the most important cities of India in the 7th century BCE.
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 (Bhallatiya Jataka) and Jain annals. It was then that the legendary Dhaj, Ror Kumar (Rai Diyach in Sindhi folklore) built Rori Shankar, Rohri and Sukkur in Pakistan in the year 450 BC.
