Central Asia is a region in Asia which stretches from the Caspian Sea in the west to China and Mongolia in the east, and from Afghanistan and Iran in the south to Russia in the north. The region consists of the former Soviet republics of Kazakhstan, Kyrgyzstan, Tajikistan, Turkmenistan, and Uzbekistan. It is also colloquially referred to as "the stans" as the countries all have names ending with the Persian suffix "-stan", meaning "land of".Central Asia was historically closely tied to the Silk Road trade routes, acting as a crossroads for the movement of people, goods, and ideas between Europe and the Far East.In the pre-Islamic and early Islamic eras (circa 1000 and earlier) Central Asia was inhabited predominantly by Iranians, populated by Eastern Iranian-speaking Bactrians, Sogdians, Chorasmians and the semi-nomadic Scythians and Dahae. After expansion by Turkic peoples, Central Asia also became the homeland for the Kazakhs, Uzbeks, Tatars, Turkmen, Kyrgyz, and Uyghurs; Turkic languages largely replaced the Iranian languages spoken in the area, with the exception of Tajikistan and areas where Tajik is spoken.
From the mid-19th century until almost the end of the 20th century, Central Asia was colonised by the Russians, and incorporated into the Russian Empire, and later the Soviet Union, which led to Russians and other Slavs emigrating into the area. Modern-day Central Asia is home to a large population of European settlers, who mostly live in Kazakhstan; 7 million Russians, 500,000 Ukrainians, and about 170,000 Germans. Stalinist-era forced deportation policies also mean that over 300,000 Koreans live there.Central Asia (2019) has a population of about 72 million, in five countries: Kazakhstan (pop. 18 million), Kyrgyzstan (6 million), Tajikistan (9 million), Turkmenistan (6 million), and Uzbekistan (35 million).

I want to replace it as it is a bit old and unsightly and seems to have a lot of "play" between on and off.
