The announcement came one day after Deena Aljuhani Abdulaziz, the mother of three who previously set up a members-only fashion business introducing edgy designers to the Gulf, told media outlets that she had been sacked.
Nervora, the Dubai-based publishers, announced Friday that Manuel Arnaut, who began his career at Vogue Portugal, had been appointed editor-in-chief effective May 7.
He is the second man appointed to lead an edition of Vogue in less than a week, following the appointment of Ghana-born Briton Edward Enninful to British Vogue.
Even in the cut-throat world of glossy magazine publishing, it was an astonishingly quick exit for a woman widely known in fashion circles and feted for putting US supermodel Gigi Hadid in a jewel-encrusted veil on the inaugural cover.
"I refused to compromise when I felt the publisher's approach conflicted with the values which underpin our readers and the role of the editor-in-chief in meeting those values in a truly authentic way," Ms Abdulaziz told Business of Fashion.
Mr Arnaut has worked for Conde Nast for more than a decade and oversaw the 2015 launch of Architectural Digest Middle East.
"The team and I are committed to working towards a Vogue Arabia that is the proud voice of the region, representing the strength and allure of the Arab woman," he said in a statement.
Nervora CEO Shashi Menon paid brief tribute to Ms Abdulaziz, who was appointed in July 2016. "As the launch editor-in-chief of Vogue Arabia, Deena Aljuhani Abdulaziz has earned a place in the history of fashion and Vogue," Ms Menon said.
Vogue Arabia launched an Arabic and English-language website last year and its print edition in March. It is published by Nervora under license agreement with Conde Nast International.
