He took part in organizing armed resistance against foreign occupation in the Skrapar-Berat area and managed to keep it free from the Italian forces.

During this period and despite his old age, Ermenji made a major contribution to the establishment of Albanian national sentiment through a series of conferences across the entire country.

In a speech he denounced the elections as stolen and called the then president Sali Berisha a Diktator Qesharak (Roughly in English: "Ridiculous Dictator").

In 2001 as leader of the Balli Kombëtar, he formed a coalition agreement with Sali Berisha during the 2001 Albanian parliamentary election.

On the 6th anniversary of his death, Ermenji's monograph Vendi që zë Skënderbeu në Historinë e Shqipërisë  - Skanderbeg’s Place in the History of Albania was published.
