Thind is the most prominent clan name found among the people living in Greater Punjab. The Thinds are well known in the areas of agriculture, military, sports and Punjabi literature. Thinds are numerously found as Sikhs, Hindus and the Muslims. Over 92% of the total Thinds of Punjab, India belong to Khatri clan (mostly Khatris of Tarkhan (Punjab) and Kamboj sub-grouping), 7% are Jats and 1 % are Saini.
Jatt writer, H. S. Duleh, says that
The people of Thind tribe, along with other Jatt tribes,came into India from the Shakastan in Middle Asia in 150 BC. The founding father of this clan was Thind Rai. Due to their enmity with Lodhis, they left Delhi at the end of 14th century to settle along the banks of Sutlej in the district of Ludhaina. Thind Jatts are found in large numbers in Ludhiana and Sangrur in Malwa but are few in numbers in Majha and Doaba. Kamboj of Thind sub-caste are mostly in Doaba. Akalai leaders Sardar Atma Singh and Sardar Balwant Singh were Kamboj of Thind clan. Some Tiwanas are also found among the Kamboj in Mahja. Some Kaura Jatts are also Kamboj. The Thinds, Tiwanas and Kaura Jatts who entered into matrimonial alliance with the Kamboj later on merged with the Kamboj community. Some of the people of Thind clan had also settled beyond Majha in Montgomery (now Pakistan). Thinds of Montgomery were both Jatts as well as Kamboj. The people of Thind clan in Punjab are very hard working, self restrained and sagacious.....Jatts of Thind clan are numerous in Punjab. The Kamboj of Thind caln are found in large numbers. Dr Karnail Singh Thind from this clan is a noted historian.[2]
The above views of H. S. Duleh have historical problems since the Kambojs (including Thind clan) are historically documented to have had very good relations with the Lodhis and there were many Kamboj "nobles, Generals, Amirs and men of learning" in the courts of the Lodhi emperors.[3] Secondly, Duleh is confusing the Thind Kamboj of Majha and Montgomery with the Jatts. H. A. Rose confirms in his Glossary of Tribes that all Thinds in Montgomery belonged only to Kamboh (Kamboj) agricultural clan and there were no Thinds of Jat background there.[4]
In Montgomery and Multan, all agriculturists no matter what caste, were known as Jatts or Arains. Author of Glossary of Tribes and Castes of Punjab while writing about Jatt Thinds remarks: "Thind is a small Jatt clan found in Ludhiana and their ancestor is Bichhu whom they adore".[5] Thus the ancestor or originator of the Ludhiana Thinds is someone called Bichhu and not Thind Rai as H. S. Duleh writes without quoting any evidence. Bichhu, the elder of the Ludhiana Thind must have belonged to Thind clan and must have migrated to Ludhiana in earlier time from the Kamboj area of Ghaggar/Ambala. Contrary to what Duleh writes, the Thind Kamboj are found in large numbers in Doaba (Jullundur, Kapurthgala), Majha (Amritsar, Tarn-Taran), and Malwa (Ferozepor, Patiala). They were also found in good numbers in Lyallpur and Montgomery districts before partition. According to Glossary of H. A. Rose, all Thinds in Montgomery belong only to Kamboj agricultural clan and there are no Jatt Thinds in Montogomery
Kamboj writer H. S. Thind is more closer to historical truth when he writes that numerous of the Kamboj including the Kamboj Thinds had fled Delhi around 1290 AD to avoid persecution by Muiz ud din Qaiqabad (1286–1290) --- a Muslim Turkic ruler and the tenth Sultan of Delhi of medieval India of the Mamluk dynasty (or Slave dynasty) since the chiefs of the Kamboj clans including the Kamboj Thinds had refused to give their daughters in marriage to the Sultan.[6] After leaving Delhi, they had moved to north-west direction and first settled on the banks of river Ghaggar between Ambala and Patiala from where they later slowly and gradually spread to Kapurthala, Jullundur and Amritsar.
