October 1st 2009 marks the 140th anniversary of the Bulgarian academy of sciences (BAN).

The Bulgarian academy of sciences was created in 1911, using the base of the existing Bulgarian literary union (BKD; founded in 1869 in Braila). According to the regulations from 1911, the Bulgarian academy of sciences is divided into three sections: history and philology; philosophy and society; nature and mathematics. The periodical published by the institution is called “Magazine of Bulgarian academy of sciences”.

The regulations of the academy were revised in 1947 to reflect the political changes in Bulgaria. The newer regulations also add new functions to the institution.
