His popularity has been fuelled through social media, including many misleading posts intended to bolster his revolutionary image.

AI-generated videos of music stars like R Kelly, Rihanna, Justin Bieber and Beyoncé are seen immortalising him through song - though they have done nothing of the sort.

Ms Ochieng said that Traoré first caught the attention of Africans when he spoke at the Russia-Africa summit in 2023, telling African leaders to "stop behaving like puppets who dance every time the imperialists pull the strings".

This speech was heavily publicised by Russian media, which has become a major player in promoting Traoré's pan-Africanist image.

Thanks to his rhetoric and pushed by a slick social media campaign, his appeal has spread around the world, including among African-Americans and Black Britons, Ms Ochieng noted.

"Everyone who has experienced racism, colonialism and slavery can relate to his messages," Ms Ochieng said, pointing out that African-American rapper Meek Mill had posted about him on X late last year, saying how much he liked his "energy and heart" - though he was ridiculed for mixing up names by referring to Traoré as Burkina Faso and later deleted the post.

But France's president is not a fan, describing Traoré as part of a "baroque alliance between self-proclaimed pan-Africans and neo-imperialists".

Emmanuel Macron was also referring to Russia and China whom he accused, in a 2023 speech, of provoking coups in Africa's former French colonies, and hypocritically stirring up old arguments over sovereignty and colonial exploitation.

Traoré's popularity comes despite the fact that he has failed to fulfil his pledge to quell a 10-year Islamist insurgency that has fuelled ethnic divisions and has now spread to once-peaceful neighbours like Benin.

His junta has also cracked down on dissent, including the opposition, media and civil society groups and punished critics, among them medics and magistrates, by sending them to the front-lines of the war against the jihadists.

For Rinaldo Depagne, the Africa deputy director of the International Crisis Group think-tank, Traoré commands such support because "he is young in a country with a young population" - the median age is 17.7 years.

"He is media-savvy, and uses the past to build his popularity as a reincarnation of Sankara," he told the BBC.

"And he knows the art of politics - how to make a nation completely traumatised by war feel there is a better future. He is really good at that game."

Sankara rose to power in a coup in 1983 at the age of 33, rallied the nation under the motto "Fatherland or death, we will win!", and was killed four years later in another coup that put Burkina Faso back in France's political orbit until Traoré's seizure of power.

Ghanaian security analyst Prof Kwesi Aning, who previously worked at the Kofi Annan International Peacekeeping Training Centre, said the popularity of the military leader reflected a political shift taking place on the continent, especially in West Africa.

A 2024 survey in 39 countries by Afrobarometer showed a drop in support for democracy, although it remained the most popular form of government.

"Democracy has failed to give hope to the youth. It has not delivered jobs or better education and health," Prof Aning told the BBC.

He said Traoré was "offering an alternative, and re-capturing the spirit of two historic epochs":

• The post-independence era, when there were leaders like Ghana's Kwame Nkrumah and Kenneth Kaunda of Zambia
• And a later era with Sankara and Ghana's Jerry Rawlings, whose coup in 1979 "was also very popular at the time".

It was Traoré who stole the show at the inauguration of Ghana's President John Mahama in January, when he arrived wearing battle fatigues with a pistol in his holster.

"There were already 21 heads of state there, but when Traoré walked in, the place lit up. Even my president's bodyguards were running after him," Prof Aning said.

Traoré offered a sharply contrasting image to some of the continent's other leaders, who struggled to walk but clung to power by rigging elections, he said.

"Traoré is stylish and confident, with a very open face and a small smile. He is also a powerful orator, and presents himself as a man of the people."

In a sign that his Russian-allied junta has made some progress on the economic front, the International Monetary Fund (IMF) and World Bank have given a generally upbeat assessment.

In a statement in early April, the IMF said that despite a "challenging humanitarian and security" environment, the economy was expected to remain "robust" in 2025, and the regime had made "commendable progress" in raising domestic revenue, containing the public wage bill, and increasing spending on education, health and social protection.

As for the World Bank, it said that inflation had surged from 0.7% in 2023 to 4.2% in 2024, but the extreme poverty rate, which refers to people living on less than $2.15 [£1.61] a day, had fallen by almost two percentage points to 24.9% because of "robust growth" in the agriculture and services sectors.

Despite these reports from US-based financial institutions, relations with both France and America have been frosty.

A recent example being the claim by the head of the US Africa Command, Gen Michael Langley, that Traoré was using Burkina Faso's gold reserves for his junta's protection rather than the nation's benefit.

This appeared to be a reference to the long-standing view of the US, and some of its African allies, that Russian forces were propping up Traoré in exchange for a stake in Burkina Faso's gold industry - undermining the military ruler's image as a leader who expelled French troops in 2023 to reclaim the country's sovereignty.

Gen Langley's comments, made in early April during a US Senate committee hearing, triggered an uproar among the captain's supporters, who felt their hero was being smeared.

This was further inflamed when shortly afterwards, the Burkinabé junta said it had foiled a coup plot, alleging the plotters were based in neighbouring Ivory Coast - where Gen Langley then made a visit.

Ivory Coast denied being involved in any plot, while the US Africa Command said Gen Langley's visit had focused on addressing "common security challenges" - including "violent extremism".

But the junta took the opportunity to organise one of its biggest rallies in Burkina Faso's capital over fears that "imperialists" and their "lackeys" were trying to depose the captain.

"Because Colin Powell lied, Iraq was destroyed. Barack Obama lied, Gaddafi was killed. But this time, their lies won't affect us," one protester, musician Ocibi Johann, told the Associated Press news agency.

Rallies in solidarity with Traoré were also held abroad, including in London, on the same day.

He took to social media afterwards, posting in French and English, to express his gratitude to them for sharing his vision "for a new Burkina Faso and a new Africa", adding: "Together, in solidarity, we will defeat imperialism and neo-colonialism for a free, dignified and sovereign Africa."

It is impossible to say how things will end for the young captain, but he - along with military leaders in Mali and Niger - have certainly shaken up West Africa, and other states have followed their example by ordering French forces to leave.

The three military-ruled neighbours have also pulled out of the regional trade and security grouping Ecowas, formed their own alliance, and have ended free trade in the region by announcing the imposition of a 0.5% tariff on goods coming into their countries.

Mr Aikins said Traoré could learn from others, pointing out that when Rawlings took power in Ghana at the age of 32, he was known as "Junior Jesus" but after 19 years he left a mixed legacy - he had been unable to stem corruption despite helping to create an "enduring" democracy.

For a "lasting legacy", Mr Aikins said, Traoré should focus on achieving peace and building strong state institutions to bring about good governance rather than "personalising" power and cracking down on dissent.
