Aliyev was a director of the Institute of History of the National Academy of Sciences of Azerbaijan. He followed the methodology of the world-famous Soviet academician V. V. Struve, who was a leading specialist in the field of ancient Oriental studies. Aliyev knew ancient dead languages including Sumerian, Akkadian and Old Persian. His works specialized in ancient Media, Atropatena and Caucasian Albania and are cited by Western experts^[2][3][4] in the relevant fields.

A pamphlet written in 1997 on architecture in Nagarno Karabakh by Aliyev and Kamil Mamedzade, the two authors also asserted that the celebrated thirteenth century Gandzasar monastery, built by the Armenian prince Hasan-Jalal Dawla,^[5] was built by Caucasian Albanians.^[6] The pamphlet, which refers to the Armenians of Karabakh as "so-called Armenians" because of their alleged descent from the purported Albanian population of the region and which others have pointed out fails properly to show readers the medieval Armenian inscriptions of the monastery,^[7] goes on to claim:

The indisputable conclusion follows from everything said above that the so-called Armenians of Karabakh and the Azerbaijanis as such (who are the descendants of the Albanian population) of northern Azerbaijan share the same mother. Both of them are completely indisputably former Albanians and therefore the Armenians as such [original emphasis] on the territory of Nagorny Karabakh, into which they surged in huge numbers after the first quarter of the nineteenth century, have no rights.^[7]
