Shirin Ebadi won the 2003 Nobel Peace Prize
Iran Awakening by Shirin Ebadi and Nabeel's Song by Jo Tatchell are two of the 20 books on the longlist for the £30,000 annual prize.
Rajiv Chandrasekaran and Rory Stewart have also been nominated for their diaries based on life in Iraq.
The shortlist will be announced on 3 May, followed by the final awards ceremony on 18 June.
Judges chair Baroness Helena Kennedy QC said: "We've had an incredibly hard time choosing our longlist as the calibre of books was really astonishing.
"It is particularly interesting that current affairs and what is happening, in particular, in Iran and Iraq are at the fore-front of non-fiction."
Other books that have been longlisted include Ian Buruma's Murder in Amsterdam, William Dalrymple for The Last Mughal and Richard Dawkins for The God Delusion.
Whitbread biography winner Brian Thompson is nominated for his book Clever Girl, A Sentimental Journey.
