It is separated narrowly from Pakistan by Afghanistan's Wakhan Corridor.

It is separated narrowly from Tajikistan by Afghanistan's Wakhan Corridor in the north, and also shares a maritime border with Oman.

The region that comprises the modern state of Pakistan was the realm of multiple empires and dynasties, including the Achaemenid; briefly that of Alexander the Great; the Seleucid, the Maurya, the Kushan, the Gupta; the Umayyad Caliphate in its southern regions, the Hindu Shahis, the Ghaznavids, the Delhi Sultanate, the Mughals, the Durranis, the Sikh Empire, British East India Company rule, and most recently, the British Indian Empire from 1858 to 1947.

The area has been ruled by numerous empires and dynasties, including the Achaemenid Empire, Sasanian Empire, Hephthalite Empire, Samanid Empire and the Mongol Empire.

In 334 BC, he invaded the Achaemenid Persian Empire and began a series of campaigns that lasted for 10 years.

The Macedonian king Alexander the Great, himself an ardent admirer of Cyrus the Great, conquered most of the Achaemenid Empire by 330 BC. Upon Alexander's death, most of the former territory of the empire fell to the rule of the Hellenistic Ptolemaic Kingdom and Seleucid Empire after the partition of Alexander’s empire, until the Iranian elites of the central plateau finally reclaimed power under the Parthian Empire by the 2nd century BC.

Successive ancient empires and kingdoms ruled the region: the Persian Achaemenid Empire (around 519 BCE), Alexander the Great's empire in 326 BCE and the Maurya Empire, founded by Chandragupta Maurya and extended by Ashoka the Great, until 185 BCE.

After the region's conquest by Alexander the Great it became part of the Greco-Bactrian Kingdom, a successor state of Alexander's empire.

By the 5th century BC, the Kings of Persia were either ruling over or had subordinated territories encompassing not just all of the Persian Plateau and all of the territories formerly held by the Assyrian Empire (Mesopotamia, the Levant, Cyprus and Egypt), but beyond this all of Anatolia and Armenia, as well as the Southern Caucasus and parts of the North Caucasus, Azerbaijan, Uzbekistan, Tajikistan, Bulgaria, Paeonia, Thrace and Macedonia to the north and west, most of the Black Sea coastal regions, parts of Central Asia as far as the Aral Sea, the Oxus and Jaxartes to the north and north-east, the Hindu Kush and the western Indus basin (corresponding to modern Afghanistan and Pakistan) to the far east, parts of northern Arabia to the south, and parts of eastern Libya (Cyrenaica) to the south-west, and parts of Oman, China, and the UAE.

Alexander founded a series of new cities, all called Alexandria, including modern Kandahar in Afghanistan, and Alexandria Eschate ("The Furthest") in modern Tajikistan.

He invited the chieftains of the former satrapy of Gandhara (a region presently straddling eastern Afghanistan and northern Pakistan), to come to him and submit to his authority.
