and the Sulaiman Mountains to the west. Muhajirs Muhajirs (meaning "migrants"), also called "Urdu-speaking people" are a collective multiethnic group who emerged through the migration of Indian Muslims from various parts of India to Pakistan starting in 1947, as a result of the world's largest mass migration. The majority of Muhajirs are settled in Sindh mainly in Karachi, Hyderabad, Sukkur and Mirpur Khas. Sizable communities of Muhajirs are also present in cities including Lahore, Multan, Islamabad, and Peshawar. Muhajirs held a dominating position during the early nation building years of Pakistan and many of Pakistan's founders were Muhajirs. The term Muhajir is also used for descendants of Muslims who migrated to Pakistan after the 1947 partition of India. Notable Muhajirs include Muhammad Ali Jinnah, Liaquat Ali Khan, Abdul Qadeer Khan, Pervez Musharraf, Hakeem Muhammad Saeed and Abdul Sattar Edhi. Muhajirs are seen as the most educated and literate ethnic group in Pakistan.

Despite living in the southeastern side towards the Indian subcontinent for centuries, they are classified as a northwestern Iranian people in accordance to their language which belongs to the northwestern subgroup of Iranian languages. According to Dr. Akhtar Baloch, Professor at University of Karachi, the Balochis migrated from Balochistan during the Little Ice Age and settled in Sindh and Punjab. The Little Ice Age is conventionally defined as a period extending from the sixteenth to the nineteenth centuries or alternatively, from 1300 to 1850, although climatologists and historians working with local records no longer expect to agree on either the start or end dates of this period, which varied according to local conditions. According to Professor Baloch, the climate of Balochistan was very cold and the region was uninhabitable during the winter so the Baloch people migrated in waves and settled in Sindh and Punjab. Brahuis The Brahui, Brahvi or Brohi, are an ethnic group principally found in Balochistan, Pakistan. They speak the Brahui language, which belongs to the Dravidian language family, although ethnically they tend to identify as Baloch. They are a small minority group in Afghanistan, where they are native, but they are also found through their diaspora in Middle Eastern states. They mainly occupy the area in Balochistan from Bolan Pass through the Bolan Hills to Ras Muari (Cape Monze) on the Arabian sea, separating
