GEOGRAPHY OF PAKISTAN

The Indus Valley civilization, one of the oldest in the world and dating back at least 5,000 years, spread over much of what is presently Pakistan. During the second millennium B.C., remnants of this culture fused with the migrating Indo-Aryan peoples. The area underwent successive invasions in subsequent centuries from the Persians, Greeks, Scythians, Arabs (who brought Islam), Afghans, and Turks. The Mughal Empire flourished in the 16th and 17th centuries; the British came to dominate the region in the 18th century. The separation in 1947 of British India into the Muslim state of Pakistan with West and East sections and largely Hindu India was never satisfactorily resolved, and India and Pakistan fought two wars - in 1947-48 and 1965 - over the disputed Kashmir territory. A third war between these countries in 1971 - in which India capitalized on Islamabad's marginalization of Bengalis in Pakistani politics - resulted in East Pakistan becoming the separate nation of Bangladesh.

Pakistan is situated in the western part of the Indian subcontinent, with Afghanistan and Iran on the west, India on the east, and the Arabian Sea on the south. The name Pakistan is derived from the Urdu words Pak (meaning pure) and stan (meaning country). It is nearly twice the size of California.
The northern and western highlands of Pakistan contain the towering Karakoram and Pamir mountain ranges, which include some of the world's highest peaks: K2 (28,250 ft; 8,611 m) and Nanga Parbat (26,660 ft; 8,126 m). The Baluchistan Plateau lies to the west, and the Thar Desert and an expanse of alluvial plains, the Punjab and Sind, lie to the east. The 1,000-mile-long (1,609-km) Indus River and its tributaries flow through the country from the Kashmir region to the Arabian Sea.
