Persuading religious conservatives, including pious Kurds and nationalists, to back the Islamist-rooted AK Party will be key in an election Erdogan hopes will bring him stronger presidential powers that opponents see as a threat to democracy.
Turkey's most dominant politician for more than a decade and founder of the AK Party, Erdogan draws much of his support from the pious masses. His rhetoric often plays on a tension reaching back to the 1920s when Mustafa Kemal Ataturk forged a secular republic from the ruins of an Ottoman theocracy.
"We will not give way to those who speak out against our call to prayer," he said in a speech in Istanbul to mark the anniversary of the 1453 Islamic conquest that turned the capital of the Byzantine Empire into the seat of Ottoman power.
"We will not give space to those who want to extinguish the fire of conquest burning in the heart of Istanbul for 562 years," he told a sea of supporters waving the red Turkish flag, most of the women covered in the Islamic headscarf and some of the men wearing headbands bearing Erdogan's name.
An AK Party video released to commemorate the conquest culminated with the Muslim call to prayer being recited from a minaret of the Hagia Sophia, Christendom's greatest cathedral for 900 years until the Ottomans turned it into a mosque.
Ataturk, who banished Islam from state affairs and promoted Western dress and women's rights, decreed it a museum in 1934. But a burgeoning sense of Islamic identity that Erdogan has encouraged has revived interest in praying there. » | Daren Butler and Humeyra Pamuk | Istanbul | Saturday, May 30, 2015
