The king of South Africa's large Zulu community has challenged a professor and cultural expert to a stick fight, saying he had been insulted, along with the entire Zulu nation.

King Misuzulu kaZwelithini issued the challenge to Prof Musa Xulu in front of thousands of people who had gathered at his newly built royal palace for the annual Reed Dance.

We are angry and we will do anything to protect and preserve our cultures, he said, according to the Timeslive news site.

Prof Xulu told the BBC he took the king's personal challenge as a joke; however, he said he was worried for his safety in case he was attacked by other Zulus.

I have received threats from hired assassins, he stated, adding that he had lodged a formal complaint with the police.

King Misuzulu did not specify exactly what Prof Xulu had said to anger him but expressed, It pains me to see another man telling me how to do my job. He elaborated that criticism of him extended to insults against the Zulu nation.

If his friends are here, go and tell him that there is a fighting ring - if he wants a stick fight because I can take him up, said the king, aged 50.

Prof Xulu elaborated that the king's anger may have stemmed from an interview where he pointed out the perceived wastefulness of moving to a new palace when significant funds had already been spent renovating the old one where the reed dance had been held for decades.

However, he stressed, talking about public finance is not an insult, clarifying that he has no personal grievances against the king.

Regarding the challenge, Prof Xulu mentioned that stick-fighting is a cultural tradition, but it typically involves equals, stating, I'm not equal to the king. Additionally, he has not practiced stick-fighting since his early teenage years.

King Misuzulu ascended to the throne in 2022, following a familial dispute that emerged after the death of his father, King Goodwill Zwelithini, and the passing of his mother soon after. Despite internal challenges to his rule, he has been recognized both by the Zulu royal household and the South African government.

While the Zulu monarchy holds no formal political power, its cultural influence is significant, representing about 20% of South Africa's population of 64 million. The entity is still funded via public taxes, with an annual budget exceeding $4.9 million.

The Zulu kingdom is renowned historically for its victorious stand against British forces during the Battle of Isandlwana in 1879.
