Greece-related violence and activism On June 18, 1988 Kartal Demirağ, a senior member of the Grey Wolves, attempted to assassinate Prime Minister Turgut Özal's at the Motherland Party congress. Özal linked it to his visit to Greece three days earlier, saying that the attempt was carried out "by a group opposed to his efforts to improve relations with Greece." On September 6, 2005, a group of nationalists, led by Grey Wolves leader Levent Temiz, stormed into an Istanbul exhibition commemorating the anti-Greek pogrom of 1955. They threw eggs and tore down photos. The Grey Wolves issued a statement denying involvement. In the 2000s the Grey Wolves routinely demonstrated outside the Ecumenical Patriarchate of Constantinople in Fener (Phanar), Istanbul and burn the Patriarch in effigy. In October 2005 they staged a rally and proceeding to the gate they laid a black wreath, chanting "Patriarch Leave" and "Patriarchate to Greece", inaugurating the campaign for the collection of signatures to oust the Ecumenical Patriarchate from Istanbul. As of 2006 the Grey Wolves claimed to have collected more than 5 million signatures for the withdrawal of the Patriarch and called on the Turkish government to have the patriarch deported to Greece. In December 2017 Grey Wolves members, among them the BBP-affiliated Alperen Ocakları, invaded the Hagia Sophia and prayed there in protest against the United States recognition of Jerusalem as capital of Israel.

According to Ruben Melkonyan, an Armenian expert in Turkish studies, Ağaoglu was a member of the Grey Wolves. On April 24, 2012, the Armenian Genocide Remembrance Day, nationalist groups including the Grey Wolves protested against the commemoration of the genocide in Istanbul's Taksim Square. In June 2015, during the visit of the Armenian pianist Tigran Hamasyan to the medieval Armenian city of Ani in Kars Province, the local Grey Wolves leader suggested that his followers should "go on an Armenian hunt."
