[14][15] The name "Iran", meaning "land of the Aryans", is the New Persian continuation of the old genitive plural aryānām (proto-Iranian, meaning "of the Aryans"), first attested in the Avesta as airyānąm (the text of which is composed in Avestan, an old Iranian language spoken in northeastern Greater Iran, or in what are now Afghanistan, Uzbekistan, Turkmenistan and Tajikistan).

"[26] Richard Foltz notes that while "A general assumption is often made that the various Iranian peoples of 'greater Iran'—a cultural area that stretched from Mesopotamia and the Caucasus into Khwarizm, Transoxiana, Bactria, and the Pamirs and included Persians, Medes, Parthians and Sogdians among others—were all 'Zoroastrians' in pre-Islamic times...
He argues that "While the various Iranian peoples did indeed share a common pantheon and pool of religious myths and symbols, in actuality a variety of deities were worshipped—particularly Mitra, the god of covenants, and Anahita, the goddess of the waters, but also many others—depending on the time, place, and particular group concerned".

With the Treaty of Gulistan of 1813 following the Russo-Persian War (1804–1813) Iran had to cede eastern Georgia, its possessions in the North Caucasus and many of those in what is today the Azerbaijan Republic, which included the khanates of Baku, Shirvan, Karabakh, Ganja, Shaki, Quba, Derbent, and parts of Talysh.

It was referred to by the Greeks as "Tylos", the centre of pearl trading, when Nearchus discovered it while serving under Alexander the Great.
[61] The influence of Iran was further undermined at the end of the 18th century when the ideological power struggle between the Akhbari-Usuli strands culminated in victory for the Usulis in Bahrain.
The Omani invasion began a period of political instability and a quick succession of outside rulers took power with consequent destruction.
According to a contemporary account by theologian, Sheikh Yusuf Al Bahrani, in an unsuccessful attempt by the Persians and their Bedouin allies to take back Bahrain from the Kharijite Omanis, much of the country was burnt to the ground.
