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. The name roughly translates from Mongolic and Turkic languages to "Sea of Islands", a reference to the large number of islands that once dotted its waters. The Aral Sea drainage basin encompasses Uzbekistan and parts of Afghanistan, Iran, Kazakhstan, Kyrgyzstan, Tajikistan, and Turkmenistan.

Uzbekistan, officially the Republic of Uzbekistan, is a doubly landlocked country located in Central Asia. It is surrounded by five countries: Kazakhstan to the north, Kyrgyzstan to the northeast, Tajikistan to the southeast, Afghanistan to the south, and Turkmenistan to the southwest, making it one of only two doubly landlocked countries on Earth, the other being Liechtenstein. Uzbekistan is part of the Turkic world, as well as a member of the Organization of Turkic States. Uzbek is the majority language, while Russian is widely spoken and understood. Islam is the predominant religion, and most Uzbeks are Sunni Muslims.
