The origin of the Urdu Language is obscure. Various theories have been given to explain it. Muhammad Husain Azad maintains that Brij Bhasha, a dialect of Western Hindi, is the basic language. After the conquest of Delhi by the Muslims, the Persian element was grafted which resulted to the existence of Urdu language.

Mahmud Sherani, on the contrary, holds that the Urdu language originated in the first contact of the Muslims and Hindus after the conquest and incorporation of the Punjab and Sind In the Empire of Mahmud of Ghazni. In his book Punjab men Urdu, he has discussed the structure and morphology of the Urdu language and has shown grammatical affinity which it has with the Punjabi language. After the occupation of Delhi by the Ghoris, the Punjabi Muslims and Hindus, who had already become familiar with the Persian language migrated to Delhi in order to run the administration of the new government. This exodus of people on a large scale from Lahore to Delhi influenced the Khari Bholi or the Hindi spoken in Delhi and its neighbourhood. In course of time the Punjabi words and idioms became interwoven in the Hindi of Delhi and thus a new language came into being.

The third theory has been recently propounded by Dr. Masud Husain of the Aligarh Muslim University. He said that the basic language spoken in Delhi at the time of Muslim conquest was Hariani. When Persian was grafted on Hariani, it resulted in the creation of the Urdu language. He has discussed the grammatical structures of Hariani and Urdu and has based his conclusion on a comparative study of the two languages.

It seems fairly clear that after the Ghori conquest of Delhi, Persian and Punjabi words got interwoven with the language which was spoken there, which was a mixture of Khari Bholi, Brij, Rajasthani, and Hariani. Languages do not originate overnight. It must have taken at least a century to give shape to the new common language of Delhi which has been called “Hindawi” or “Dahlavi” by Amir Khusrau. Later Abul Fazl also called it the Dahlavi language. Amir Khusrau used “Dahlavi” or “Hindavi” medium in his compositions which he has mentioned in the introduction of his “Ghurratu Kamal”.

From the very beginning when Delhi became a great center of the Sufis, they employed the Hindavi language for preaching their message. They found Hindavi to be the most suitable medium for conveying their messages to the masses. Baba Farid feely used Hindavi words in his conversation with his disciples. Some Hindavi utterances have been preserved by Mir Khurd in the Siyarul Auliya. In Fawaidul Fuad, Shaikh Nizamuddin also used Hindavi language in his conversation with his disciple.

In the development of early Urdu or Hindavi, the Bhagat poets have also played an important role. The language used by Namdeo, Kabir, Pipa and Ravidas is hardly different from the one used by the Sufis. As both the Bhagats and the sufis aimed atreaching the people, they employed the all-India medium available, the Hindavi, which have been familiar all over the country.

After the advent of the Mughals on the stage of Indian history, the Hindavi language acquired greater flexibility and range. Persian words and phrases came into vogue freely. The Hindavi of this period was known as the Rekhta, or the Hindustani and later as urdu. Perfect amity and tolerance between Hindus and Muslims tended to foster the Rekhta or Urdu, which represented the principle of unity in diversity, so marked a feature of Indian life at its best.

During Akbar’s reign, translations were made from Sanskrit into Persian and Hindus and Muslims came very close to each other. Akbar’s intimate relation with the Rajputs indirectly helped the development of Urdu. Raja Todar Mal ordered all government officials to acquire profiency in Persian as a condition for promotion. This indirectly led to the propagation of Urdu all over the country and finally to its standardization in the time of Shah Jahan and Aurangzeb, when the synthetic character of Urdu (Rekhta) acquired a complete form and greater content and power.

The famous poets of this period who wrote in Urdu were Chandar Bhan Brahman, Mu’izzuddin, Ja’far, Mirza Kashmir and Mirza Bedil. Shamsuddin Wali is regarded as the founder of modern Urdu poetry. He freely used the Persian izafat and tarkib. Wali was followed by Abru, Arzu, Hatim and others at Delhi who standardized Urdu prosody.

The Urdu language was enriched from generation to generation, mainly through accumulated wisdom, techniques and cultural traditions. Through its medium the different sections of Indian society found the way to perfect comprehension of one another.
