The culture ministry in Morocco has accused Adidas of appropriating Moroccan culture in its new jerseys for Algeria’s football team.
Adidas said the design was inspired by the Mechouar Palace in Algeria.
However the geometric blue, teal and yellow design is a pattern called zellige, which is common in Moroccan mosaics, the ministry’s lawyer said.
Lawyer Mourad Elajouti wrote on Facebook that he had issued a legal warning to Adidas, on behalf of Morocco’s Ministry of Culture.
In a letter to the company’s chief executive Kasper Rorsted, Mr Elajouti said the new design was cultural appropriation and “an attempt to steal a form of Moroccan cultural heritage and use it outside its context”.
He has demanded the German sportswear brand remove the design within two weeks.
Mr Elajouti added that Algeria’s 2022-2023 season kit “contributes to the loss and distortion of the identity and history of these [zellige] cultural elements”.
Algeria and Morocco share a nearly 2,000 km (1,242 miles) border, which has been a source of tension since independence from French colonial rule.
In 1963, they had the Sand War over Morocco’s claim to territory in Algeria.
Later on, Algeria backed the Polisario Front’s campaign for Western Sahara’s independence from Morocco, leading to the 1975-1991 Western Sahara War.
The border was then closed in 1994 for security reasons after militant Islamists bombed a hotel in the historic Moroccan city of Marrakesh.
More recently, in 2021 Algeria cut diplomatic ties with its neighbour, accusing Morocco of “hostile acts”. Morocco called the move “completely unjustified”.
