North-western Iranics are a sub-group of the Iranic race. Notable ethnicities within this sub-group include the Kurds and the Baloch.
The earliest known north-western Iranics are the Median people, who are assumed by many to be the ancestors of all north-western Iranics. They ruled over a vast empire (from 678 BC to 549 BC) prior to the establishment of the Achaemenid Empire by Cyrus the Great (who himself was half Median), and are as a result not just the first north-western Iranic empire, but also the first Iranic empire to ever exist:
The Parthians were another north-western Iranic people, who ruled over a vast empire in between the reign of the Seleucids and the Sassanians (247 BC - 224 AD):
The Indo-Parthians were another north-western Iranic empire related to the Parthians, who ruled over what is now Afghanistan and Pakistan (12 BC - 130 AD) prior to the establishment of Parthia proper. This marked the first major wave of north-western Iranics into Pakistan:
During the Sassanian period, more north-western Iranics migrated to what is now Pakistan, and another major wave came during the rule of the Seljuq Empire, with presumably minor waves of migrations in between and probably even afterwards. Eventually, these north-western Iranics would primarily form the Baloch people, one of Pakistan's many ethnic groups. Pakistan's largest province (Balochistan) is also named after them, as it has been their abode for many centuries. However, many Baloch did end up migrating to Sindh and the Punjab, so much so that it is estimated that more Baloch live in these regions rather than in Balochistan itself. These Baloch don't typically follow Baloch customs or speak Balochi, but tend to speak Seraiki instead. In fact, the very word Seraiki roughly translates to "up north" in Sindhi, reflecting the fact that it has principally been the language of migrants from Balochistan to Sindh and southern Punjab.
During the Islamic rule over the region, it is said that many Baloch formed a part of the armies of the Ummayads and the Ghaurids, assisting them in their conquests throughout the region. However, the Baloch did not have amicable relations with the Ghaznavids and as a result fought many battles with them. The city of Dera Ghazi Khan is also named after a Baloch, more specifically a mercenary from the Islamic era who went by the name of Ghazi Khan. The Rind dynasty which ruled over much of what is now southern Pakistan was also founded by the Baloch, with it's most respected Sultan being Mir Chakar Rind, the main folk-hero of the Baloch who carried a sword that apparently nobody else was strong enough to hold, at one point managed to raid the city of Delhi, and also assisted Humayun in resurrecting the Mughal Empire.

The Durrani Empire also allied itself with the Baloch people, with many of them serving in the Durrani military as it fought against the Sikh, Mughal and Maratha empires.
