A great portion of the historical chronicles given in Shahnameh is based on this epic and there are in fact various phrases and words which can be matched between Ferdowsi's poem and this source, according to Zabihollah Safa. The text is written in the late Middle Persian, which was the immediate ancestor of Modern Persian. Many other Pahlavi sources were used in composing the epic, prominent being the Kārnāmag-ī Ardaxšīr-ī Pābagān, which was originally written during the late Sassanid era and gave accounts of how Ardashir I came to power which, because of its historical proximity, is thought to be highly accurate. Some claim that Ferdowsi also used Zoroastrian nasks, such as the now-lost Chihrdad, as sources as well. The style of the Shahnameh shows characteristics of both written and oral literature. These verses, which deal with the rise of the prophet Zoroaster, were afterward incorporated by Ferdowsi, with acknowledgment, in his own poem.

The first to undertake the versification of the Pahlavi chronicle was Daqiqi, a contemporary of Ferdowsi, poet at the court of the Samanid Empire, who came to a violent end after completing only 1,000 verses. Ferdowsi added material continuing the story to the overthrow of the Sasanians by the Muslim armies in the middle of the seventh century. The X wadāynāmag contained historical information on the later Sasanian period, but it does not appear to have drawn on any historical sources for the earlier Sasanian period (3rd to 4th centuries). This prose Shahnameh was in turn and for the most part the translation of a Pahlavi ( Middle Persian) work, known as the X wadāynāmag "Book of Kings", a late Sasanian compilation of the history of the kings and heroes of Persia from mythical times down to the reign of Khosrau II (590–628).

It is based mainly on a prose work of the same name compiled in Ferdowsi's earlier life in his native Tus. The Shahnameh is an epic poem of over 50,000 couplets written in Early New Persian. A small portion of Ferdowsi's work, in passages scattered throughout the Shahnameh, is entirely of his own conception. Many such accounts already existed in prose, an example being the Abu-Mansuri Shahnameh.

The Shahnameh is a monument of poetry and historiography, being mainly the poetical recast of what Ferdowsi, his contemporaries, and his predecessors regarded as the account of Iran's ancient history. The assassination of Khosrau II in a manuscript of the Shahnameh of Shah Tahmasp made by Abd al-Samad in 1535įerdowsi started writing the Shahnameh in 977 and completed it on 8 March 1010. It is also important to the contemporary adherents of Zoroastrianism, in that it traces the historical links between the beginnings of the religion and the death of the last Sasanian emperor, which brought an end to the Zoroastrian influence in Iran. The work is of central importance in Persian culture and Persian language, regarded as a literary masterpiece, and definitive of the ethno-national cultural identity of Iran.

Iran, Azerbaijan, Afghanistan, Tajikistan and the greater region influenced by Persian culture such as Armenia, Dagestan, Georgia, Turkey, Turkmenistan and Uzbekistan celebrate this national epic. It tells mainly the mythical and to some extent the historical past of the Persian Empire from the creation of the world until the Muslim conquest in the seventh century. Consisting of some 50,000 " distichs" or couplets (two-line verses), the Shahnameh is one of the world's longest epic poems. 9 CE and is the national epic of Greater Iran.
