Calling Turks the “future of Europe,” Turkey’s president on Friday implored his compatriots living on the Continent to have multiple children as an act of revenge against the West’s “injustices.”

“Go live in better neighborhoods. Drive the best cars. Live in the best houses,” President Recep Tayyip Erdogan said Friday in the city of Eskisehir, while campaigning for a referendum that would solidify his power. “Make not three, but five children. Because you are the future of Europe. That will be the best response to the injustices against you.”

The remarks come at a time of increasingly fraught relations between Europe and Turkey in the wake of the migrant crisis, the concurrent rise of Islamic terrorism and right-wing nationalism in Europe, and a crackdown on civil liberties in Turkey.

Turkish citizens have lived in Europe for decades and have often been the focus of anti-immigrant sentiment. Mr. Erdogan has found that addressing overseas Turks is a convenient way to stir his own citizens’ nationalism and attack a Europe that has become increasingly hostile to Turkey as his government becomes ever more authoritarian.
