The Shahnameh, also transliterated Shahnama, is a long epic poem written by the Persian poet Ferdowsi between c. 977 and 1010 CE and is the national epic of Greater Iran. Consisting of some 50,000 distichs or couplets, the Shahnameh is one of the world's longest epic poems, and the longest epic poem created by a single author. 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. 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.

The Samanid Empire, also known as the Samanian Empire, Samanid dynasty, Samanid amirate, or simply as the Samanids, was a Persianate Sunni Muslim empire, of Iranian dehqan origin. The empire was centred in Khorasan and Transoxiana; at its greatest extent encompassing Persia and Central Asia, from 819 to 999.
