The first few centuries of the Christian Era and a couple of centuries prior to that constitute the golden age of Ror history. Not only did Rors have ruling seats of power in Gujarat, Rajasthan, Haryana and Sindh; during the times of Rai Dewaji in the 5th century AD, they consolidated their influence in the entire region from Afghanistan to Kanauj in India.

The fort at BhainsRor in Southern Rajasthan is supposed to have come up in the 2nd century B.C. and the Kagarol (Kaga Ror) ruins near present-day Agra have also pointed to a similar time-line for another branch of Rors who ruled from there. The coins found in the Agra circle by Sir Alexander Cunningham seem to indicate a close relationship between the Ror rulers of the area and the rulers of Hastinapur and Indraprastha. A few coins found close to the site have been dated to the 3rd century CE by Cunningham as a result of the general style of the coins and the type of Sanskrit used.

Ror rulers of Sindh

Following the foundation of Rori Shankar by Dhaj, Ror Kumar (Rai Diyach in Sindh), 41 kings followed him one after the other till Dadror. Listing them starting from 450 BC till 489 AD, the dynasty grew as follows:

Dhaj, Ror Kumar Kunak Rurak Harak Devanik Ahinak Paripat Bal Shah Vijay Bhan Khangar Brihadrath Har Ansh Brihad-datt Ishman Sridhar Mohri Prasann Ket Amirvan Mahasen Brihad-dhaul Harikeert Som Mitravan Pushyapata Sudaav Bideerakh Nahakman Mangalmitra Surat Pushkar Ket Antar Ket Sutjaya Brihad-dhwaj Bahuk Kampjayi Kagnish Kapish Sumantra Ling-laav Manasjit Sunder Ket Dadror

The bards report that Dadror was poisoned by his head priest, Dewaji in 620 AD and he was followed by five Brahmin kings before the capture of Rori or Al Ror by the Arabs. On the other hand, written records like the Chachnama report that the Brahmin usurper was Chach and not Dewaji.Considering that the bards may have made a mistake in their orally transmitted reports from generation to generation, we can place a greater faith on the date of 620 AD and that corresponds well with Chach, the usurper's lifetime. That would mean that the dynasty reported as the Rai dynasty was a continuation of Ror rule in Sindh and Rai Sahasi II was not killed by Chach jumping onto his horse's back in an open field (as in Chachnama) but in cold blood by mixing poison in his food.

Wink reports on the possibility of the corruption of the Sanskrit names and renders them as related in parenthesis in the following chronology of the Ror Rai rulers (489 - 632 AD) of Rori or Alor in Sindh:

Rai Dewaji (Devaditya) He was a powerful chief who forged alliances and extended his rule east of Makran and west of Kashmir and Kannauj, south to the port of Surat and north to Kandahar Rai Sahiras (Shri Harsha) Rai Sahasi (Sinhasena) Rai Sahiras II Died battling the King of Nimroz Rai Sahasi II (Brother of Rana Maharath of Chittor)

Loss of Sindh

Rors continued to hold several big forts in Sindh till the Arab invasion of AD 711 and some of the longest battles between the Arabs and Indians were fought at the three forts of Rori (Raor), BahRor and AghRor. Chachnama mentions the occurrence of a "Jauhar" during the siege of the BahRor fort. All men of the military class, Ror Thakurs and their relatives were put to death after the Arab victories. Elsewhere in Sindh, a noble by the name of Dahir Ror is said to have engaged Bin Qasim and his forces in an intense battle before the final engagement between the Arab forces and Raja Dahar's army. After the occupation of Sind by the Arabs, the surviving Ror warriors came away and some of them settled in Ahar, from where the Aharya Ranas of Mewar derived their name.
