The Amu Darya is a major river in Central Asia and Afghanistan. Rising in the Pamir Mountains, north of the Hindu Kush, the Amu Darya is formed by the confluence of the Vakhsh and Panj rivers, in the Tigrovaya Balka Nature Reserve on the border between Afghanistan and Tajikistan, and flows from there north-westwards into the southern remnants of the Aral Sea. In its upper course, the river forms part of Afghanistan's northern border with Tajikistan, Uzbekistan, and Turkmenistan. In ancient history, the river was regarded as the boundary of Greater Iran with "Turan", which roughly corresponded to present-day Central Asia. The Amu Darya has a flow of about 70 cubic kilometres per year on average.

The Aral Sea was an endorheic lake lying between Kazakhstan to its north and Uzbekistan to its south which began shrinking in the 1960s and largely dried up by the 2010s. It was in the Aktobe and Kyzylorda regions of Kazakhstan and the Karakalpakstan autonomous region of Uzbekistan.

It is the northern and eastern of the two main rivers in the endorheic basin of the Aral Sea, the other being the Amu Darya (Jayhun).
The Karakum Desert, also spelled Kara-Kum and Gara-Gum, is a desert in Central Asia.

Today Khwarazm belongs partly to Uzbekistan and partly to Turkmenistan.

The Bactria–Margiana Archaeological Complex (BMAC) is the modern archaeological designation for a particular Middle Bronze Age civilization of southern Central Asia also known as the Oxus Civilization. The civilization's urban phase or Integration Era, was dated in 2010 by Sandro Salvatori to c. 2400–1950 BC, but a different view is held by Nadezhda A. Duvoba and Bertille Lyonnet, c. 2250–1700 BC.

The Tazabagyab culture is from late Bronze Age, ca. 1850 BC to 1500 BC, which flourished in lower Zeravshan valley, as well as along the lower Amu Darya towards the south shore of the Aral Sea; this last region is known as Khwarazm or Khorezm. Earlier it was thought to be from ca. 1500 BC to 1100 BC and regarded a southern offshoot of the Andronovo culture, composed of Indo-Iranians, but Stanislav Grigoriev, in a recent study asserts that Tazabagyab is not part of Andronovo culture.
