Context paragraphs:
Demographics of Central Asia: Central Asia is a diverse land with many ethnic groups, languages, religions and tribes.  The nations which make up Central Asia are five of the former Soviet republics: Kazakhstan, Kyrgyzstan, Turkmenistan, Tajikistan, and Uzbekistan, which have a total population of about /1e6 round 0 million.  Afghanistan is not always considered part of the region, but when it is, Central Asia has a total population of about 122 million (2016).  Additionally, Pakistan has a large population of central Asian peoples even though it is not categorized as a central Asian nation.  Most central Asians belong to religions which were introduced to the area within the last 1,500 years, such as Sunni Islam, Shia Islam, Ismaili Islam, Tengriism, and Syriac Christianity.  Buddhism, however, was introduced to Central Asia over 2,200 years ago, and Zoroastrianism, over 2,500 years ago.

Persian literature: Persian literature (Persian: ادبیات فارسی‎ ‎ "adabiyāt-e fārsi"), comprises oral compositions and written texts in the Persian language and it is one of the world's oldest literatures.  It spans two-and-a-half millennia, though much of the pre-Islamic material has been lost.  Its sources have been within Greater Iran including present-day Iran, Iraq, the Caucasus, and Turkey, regions of Central and South Asia where the Persian language has historically been either the native or official language.  For instance, Mowlana Rumi, one of best-loved Persian poets, born in Balkh or Vakhsh (in what is now Afghanistan), wrote in Persian, and lived in Konya, then the capital of the Seljuks in Anatolia.  The Ghaznavids conquered large territories in Central and South Asia and adopted Persian as their court language.  There is thus Persian literature from Iran, Mesopotamia, Azerbaijan, the wider Caucasus, Turkey, western parts of Pakistan, India, Tajikistan and other parts of Central Asia.  Not all Persian literature is written in Persian, as some consider works written by ethnic Persians in other languages, such as Greek and Arabic, to be included.  At the same time, not all literature written in Persian is written by ethnic Persians or Iranians, as Turkic, Caucasian, and Indic poets and writers have also used the Persian language in the environment of Persianate cultures.

Black Death migration: The Black Death, caused by "Yersinia pestis", is enzootic (commonly present) in populations of ground rodents in Central Asia.  Morelli et al. (2010) reported the origin of the plague bacillus to be in China.  An older theory places the first cases in the steppes of Central Asia, and others, such as the historian Michael W. Dols, argue that the historical evidence concerning epidemics in the Mediterranean and specifically the Plague of Justinian point to a probability that the Black Death originated in Central Asia (not Africa - Asia (http://www.medicalnewstoday.com/articles/206309.php) where it then became entrenched among the rodent population.

Tulip: Tulips ("Tulipa") form a genus of spring-blooming perennial herbaceous bulbiferous geophytes (having bulbs as storage organs).  The flowers are usually large, showy and brightly coloured, generally red yellow or white.  They often have a different coloured blotch at the base of the tepals (petals), internally.  because of a degree of variability within the populations, and a long history of cultivation, classification has been complex and controversial.  The tulip is a member of the Liliaceae (lily) family, along with 14 other genera, where it is most closely related to "Amana", "Erythronium" and "Gagea" in the tribe Lilieae.  There are about 75 species, and these are divided between four subgenera.  The name "tulip" is thought to be derived from a Persian word for turban, which it may have been thought to resemble.  Tulips originally were found in a band stretching east from Turkey to Central Asia, but since the seventeenth century have become widely naturalised and cultivated ("see map").  In their natural state they are adapted to mountainous areas with temperate climates.  Flowering in the spring, they become dormant in the summer once the flowers and leaves die back, emerging above ground as a shoot from the underground bulb in early spring.

Islam in Central Asia: Islam in Central Asia has existed since the beginning of Islamic history.  Islam is the most widely practiced religion in Central Asia.  The Hanafi school of thought of Sunnism is the most popular, with Shiism of Imami and Ismaili denominations predominating in the Pamir plateau and the western Tian Shan mountains (almost exclusively Ismailis), while boasting to a large minority population in the Zarafshan river valley, from Samarkand to Bukhara (almost exclusively Imamis).  Islam came to Central Asia in the early part of the 8th century as part of the Muslim conquest of the region.  Many well-known Islamic scientists and philosophers came from Central Asia, and several major Muslim empires, including the Timurid Empire and the Mughal Empire, originated in Central Asia.  In the 20th century, severe restrictions on religious practice were enacted by the Soviet Union in Soviet Central Asia and the People's Republic of China in Xinjiang.  Concerns about Islamic radicalism and religious freedom in the region persist to this day.

Buddhism in Central Asia: Buddhism in Central Asia refers to the forms of Buddhism that existed in Central Asia, which were historically especially prevalent along the Silk Road.  The history of Buddhism in Central Asia is closely related to the Silk Road transmission of Buddhism during the first millennium of the common era.

Virgilia (plant): Virgilia is a genus of Southern African trees in the family Fabaceae, having shiny to hairy pinnate leaves and attractive mauve to pink pea-shaped flowers followed by leathery pods.  They are valued as useful ornamental trees by gardeners, particularly the well-known species "Virgilia divaricata" ('Tree in a Hurry', 'Cape Lilac', 'Blossom Tree') and "Virgilia oroboides" ('Pink Blossom Tree'), despite having a comparatively short life (15 years).  They prefer well drained soils; some will then grow 2m in the first season.  They will tolerate wind and have dense foliage growing close to the ground, so they are useful as pioneer species for privacy and wind protection.  The common name in South Africa (in Afrikaans) is keurboom, meaning 'choice tree'.

List of World Heritage Sites in Eastern Europe: The UNESCO (United Nations Educational, Scientific and Cultural Organization) has designated 77 World Heritage Sites in nine countries (also called "state parties") of Eastern Europe; defined here to mean the former Eastern Bloc countries not including the Baltic Countries (which are in Northern Europe) or former Yugoslavia and Albania (which are in Southern Europe) or the parts of Germany that once comprised East Germany (which are included in Western Europe): Russia, Belarus, Poland, Czech Republic, Slovakia, Hungary, Ukraine, Moldova, Romania and Bulgaria.  Only the European part of Russia is included here; the Asian part is included in Central Asia.  Although they have territory in Eastern Europe, uniquely positioned Turkey and the Caucasian countries of Armenia, Georgia, and Azerbaijan are not included here but in Western Asia, and Kazakhstan is included in Central Asia.

Soviet Central Asia: Soviet Central Asia refers to the section of Central Asia formerly controlled by the Soviet Union, as well as the time period of Soviet administration (1918–1991).  Central Asian SSRs declared independence in 1991.  In terms of area, it is nearly synonymous with Russian Turkestan, the name for the region during the Russian Empire.  Soviet Central Asia went through many territorial divisions before the current borders were created in the 1920s and 1930s.
