Rustemi was the leader of both democratic organisations "Atdheu" and "Bashkimi", and also a member of the democratic opposition in the Albanian National Assembly preceding the Revolution of June 1924.

Avni Rustemi was an eminent democratic activist and ideologist.

"[citation needed] His ideology was further enforced in the National Assembly of 1924; he became a deputy of the people from ex-prefecture of Kosovo.

[1] Albanians generally see Rustemi as a national hero for the assassination of Essad Pasha Toptani, whom they think of as a traitor who developed good relations with the Kingdom of Serbia and Kingdom of Montenegro.

As a member of the Toptani family, King Zog I ordered an assassination of him, ultimately leading to his popularity decreasing in the country.
