"Asia Central es una región de Asia que va desde el mar Caspio hasta las fronteras de China y de las de Rusia hasta Asia del Sur. Asia Central se ha caracterizado históricamente por sus pueblos nómadas y por la Ruta de la Seda. Como resultado ha sido la vía por la que se han movido personas, bienes, e ideas, entre Europa, Oriente Medio, Asia del Sur, y Asia Oriental. Existen varias definiciones de lo que constituye Asia Central. Actualmente se sigue la definición de la subregión de la ONU que la compone de cinco repúblicas ex-Soviéticas Kazajistán, Kirguistán, Tayikistán, Turkmenistán y Uzbekistán. En ocasiones, por razones étnicas se incluyen Mongolia, Afganistán, Pakistán del Norte, Irán del Noreste, Noroeste de India y el China del Oeste. En ocasiones se amplia aún más para acoger otras partes de China como Qinghai, Tíbet, Gansu y Mongolia Interior así como el sur de Siberia. Previo al nacimiento de Mahoma y durante la Edad Media la región estaba compuesta de pueblos iranios que incluía a sogdianos y corasmios sedentarios y a escitas y alanos semi-nómadas. La población sedentaria juega un importante papel en la historia de la zona, así los tayikos, pastunes, pamiris y otros pueblos iranios siguen presentes en la zona. Pero tras la expansión de los pueblos túrquicos, se convirtió también en patria de uzbekos, kazajos, kirguís y uigures de forma que en ocasiones Asia Central recibe el nombre de Turquestán."
"Central Asia or Middle Asia is the core region of the Asian continent and stretches from the Caspian Sea in the west to China in the east and from Afghanistan in the south to Russia in the north. It is also sometimes referred to as Middle Asia, and, colloquially, "the 'stans" (as the six countries generally considered to be within the region all have names ending with the Persian suffix "-stan", meaning "land of") and is within the scope of the wider Eurasian continent. In modern contexts, all definitions of Central Asia include these five republics of the former Soviet Union: Kazakhstan (pop. 17 million), Kyrgyzstan (5.7 million), Tajikistan (8.0 million), Turkmenistan (5.2 million), and Uzbekistan (30 million), for a total population of about 66 million as of 20132014. Afghanistan (pop. 31.1 million) is also sometimes included. Various definitions of Central Asia's exact composition exist, and not one definition is universally accepted. Despite this uncertainty in defining borders, the region does have some important overall characteristics. For one, Central Asia has historically been closely tied to its nomadic peoples and the Silk Road. As a result, it has acted as a crossroads for the movement of people, goods, and ideas between Europe, Western Asia, South Asia, and East Asia. During pre-Islamic and early Islamic times, Central Asia was a predominantly Iranian region that included the sedentary Eastern Iranian-speaking Bactrians, Sogdians and Chorasmians, and the semi-nomadic Scythians and Parthians. The ancient sedentary population played an important role in the history of Central Asia. After expansion by Turkic peoples, Central Asia also became the homeland for many Turkic peoples, including the Kazakhs, Uzbeks, Turkmen, Kyrgyz, Uyghurs and other extinct Turkic nations. Central Asia is sometimes referred to as Turkestan. Since the earliest of times, Central Asia has been a crossroads between different civilizations. The Silk Road connected Muslim lands with the people of Europe, India, and China. This crossroads position has intensified the conflict between tribalism and traditionalism and modernization. From the mid-19th century, up to the end of the 20th century, most of Central Asia was part of the Russian Empire and later the Soviet Union, both being Slavic-majority countries. As of 2011, the five "'stans'" are still home to about 7 million Russians and 500,000 Ukrainians."
