Hindustan

[12] In 515 BCE, Darius I annexed the Indus Valley including Sindhu, the present day Sindh, which was called Hindu in Persian.

[2] In middle Persian, probably from the first century CE, the suffix -stān was added, indicative of a country or region, forming the present word Hindūstān.

[15][16] Historian B. N. Mukherjee states that from the lower Indus basin, the term Hindūstān got gradually extended to "more or less the whole of the subcontinent".

In the time of the Delhi Sultanate and the Mughal empire, the ruling elite and its Persian historiographers made a further distinction between "Hindustan" and "Hind".

Muhammad Ali Jinnah, the founder of Pakistan, and his party the Muslim League, insisted on calling the modern-day Republic of India "Hindustan" in reference to its Hindu-majority population.

After the advent of Islam and the Muslim conquests, the meaning of Hindustan interacted with its Arabic variant Hind, which was derived from Persian as well, and almost became synonymous with it.

The Arabs, engaging in oceanic trade, included all the lands from Tis in western Balochistan (near modern Chabahar) to the Indonesian archipelago, in their idea of Hind, especially when used in its expansive form as "Al-Hind".

[28][29][30] Indeed, in 1220 CE, historian Hasan Nizami described Hind as being "from Peshawar to the shores of the [Indian] Ocean, and in the other direction from Siwistan to the hills of Chin.

"[31] With the Turko-Persian conquests starting in the 11th century, an accurate meaning of Hindustan took shape, defining the land of the river Indus.

The self proclamation was done to enforce Hindu social code Dharmashastra over his reign and refer to his country as being inhabitable for Hindus.

For instance, Rennel produced an atlas titled the Memoir of a Map of Hindoostan or the Mogul Empire in 1792, which actually depicted the Indian subcontinent.

[42][43] J. Bernoulli, to whom Hindustan meant the Mughal Empire, called his French translation La Carte générale de l'Inde (General Map of India).

[46][36] An Anglo-Indian Dictionary published in 1886 states that, while Hindustan means India, in the native parlance it had come to represent the region north of Narmada River excluding Bihar and Bengal.

[47] Mohammad Iqbal's poem Tarānah-e-Hindī ("Anthem of the People of Hind") was a popular patriotic song among Indian independence activists.

[48] Sāre jahāṉ se acchā Hindustān hamārā (the best of all lands is our Hindustan) The 1940 Lahore Resolution of the All-India Muslim League demanded sovereignty for the Muslim-majority areas in the northwest and northeast of British India, which came to be called 'Pakistan' in popular parlance and the Dominion of India came to be called 'Hindustan'.
