Eastern literature in the middle ages

The influence of Persian literature on world literature
Sufi literature
Some of Persia's best-beloved medieval poets were Sufis, and their poetry was, and is, widely read by Sufis from Morocco to Indonesia. Rumi, in particular, is renowned both as a poet and as the founder of a widespread Sufi order. Hafez, too, is hugely admired in both East and West, and he was inspired by Sufism if he was not actually a Sufi himself. The themes and styles of this kind of devotional poetry have been widely imitated by many Sufi and non-Sufi poets. See also the article on Sufi poetry.
Many notable texts in Persian mystic literature are not poems, yet highly read and regarded. Among those are Kimiya-yi sa'ādat, Asrar al-Tawhid and Kashf ul Mahjoob.
Beginning in the early 16th century, Persian traditions had a large impact on the Georgian ruling elites, which in turn resulted in Persian influence on Georgian art, architecture, and literature. This cultural influence lasted until the arrival of the Russians.
Jamshid Sh. Giunashvili remarks on the connection of Georgian culture with that of the Persian literary work Shahnameh:
The names of many Šāh-nāma heroes, such as Rostom-i, Thehmine, Sam-i, or Zaal-i, are found in 11th- and 12th-century Georgian literature. They are indirect evidence for an Old Georgian translation of the Šāh-nāma that is no longer extant. ...
The Šāh-nāma was translated, not only to satisfy the literary and aesthetic needs of readers and listeners, but also to inspire the young with the spirit of heroism and Georgian patriotism. Georgian ideology, customs, and worldview often informed these translations because they were oriented toward Georgian poetic culture. Conversely, Georgians consider these translations works of their native literature. Georgian versions of the Šāh-nāma are quite popular, and the stories of Rostam and Sohrāb, or Bījan and Maniža became part of Georgian folklore.
Asia Minor
Despite that Asia Minor (or Anatolia) had been ruled various times prior to the Middle Ages by various Persian-speaking dynasties originating in Iran, the language lost its traditional foothold there with the demise of the Sassanian Empire. Centuries later however, the practise and usage in the region would be strongly revived. A branch of the Seljuks, the Sultanate of Rum, took Persian language, art and letters to Anatolia. They adopted Persian language as the official language of the empire. The Ottomans, which can "roughly" be seen as their eventual successors, took this tradition over. Persian was the official court language of the empire, and for some time, the official language of the empire. The educated and noble class of the Ottoman Empire all spoke Persian, such as sultan Selim I, despite being Safavid Iran's archrival and a staunch opposer of Shia Islam. It was a major literary language in the empire. Some of the noted earlier Persian literature works during the Ottoman rule are Idris Bidlisi's Hasht Bihisht, which begun in 1502 and covered the reign of the first eight Ottoman rulers, and the Salim-Namah, a glorification of Selim I. After a period of several centuries, Ottoman Turkish (which was highly Persianised itself) had developed towards a fully accepted language of literature, which was even able to satisfy the demands of a scientific presentation. However, the number of Persian and Arabic loanwords contained in those works increased at times up to 88%. The Ottomans produced thousands of Persian literary works throughout their century long lifespan.
