KABUL - Mullah Haibatullah Akhundzada, named Wednesday as the Afghan Taliban's new leader, was a senior judge during the insurgent group's five-year rule over Afghanistan and a close confidant of its founder Mullah Omar.
Believed to be in his fifties, he hails from Afghanistan's southern province of Kandahar like both his former boss - Mullah Akhtar Mansour, who was killed in a US drone strike on Saturday - and Omar, who died in 2013.
Akhundzada went on to become the group's "chief justice" after a US-led invasion toppled the Taliban government in 2001.
He was one of Mansour's deputies alongside Sirajuddin Haqqani, leader of the feared Haqqani network based out of eastern Afghanistan.
Several senior Taliban sources have said Mansour bequeathed Akhunzada the leadership in his will, though some observers have argued in the past that hereditary succession is against the Taliban's ideology.
Akhundzada is not known for his prowess on the battlefield, having preferred a life of religious and legal study.
He is said to have issued many of the rulings on how Muslims should comply with the Taliban's extreme interpretation of Islam, and adjudicated internal disputes.
On Wednesday, the Afghan Taliban’s newly appointed leader vowed there would be no return to peace talks with the government, in an audio recording provided by the group days after a U.S. drone killed his predecessor, Mullah Akhtar Mansour, in Pakistan.
“No, no we will not come to any type of peace talks,” the man, identified as Haibatullah Akhundzada, said in the recording provided by the Taliban’s official spokesman.
The voice could not be independently verified if it was that of Akhundzada or when it was recorded, Reuters reported.
"He is a religious scholar who was close to Mullah Omar, a close confidant and an adviser on religious issues who wrote fatwas, and was on the council of Ulema (Muslim scholars)," said Thomas Ruttig, a former diplomat and co-director of the Kabul-based Afghan Analysts Network.
A senior Taliban source familiar with proceedings at the Shura (council) which appointed Akhundzada said he was a unanimous choice, adding the group's rank and file looked to him as a "spiritual leader" who had taught thousands of students in both Pakistan and Afghanistan over 25 years.
According to Rahimullah Yousafzai, considered the region's foremost expert on the Taliban, Akhundzada was in Pakistan during the 1979-89 Soviet occupation of Afghanistan - unlike Omar and Mansour, who earned reputations as fighters as part of the US-backed mujahideen.
But he returned to his homeland in time to attend the meeting in the town of Spin Boldak in Kandahar in 1994 at which Omar declared the birth of the Taliban movement, according to the senior militant source.
It is unclear whether he will follow Mansour in shunning peace negotiations with the Afghan government, though analysts believe he will be more heavily reliant on his Shura than his predecessors.
In terms of seniority, he was second only to Taliban co-founder Mullah Abdul Ghani Baradar.
"Akhundzada was chosen to avoid further conflict and consultation," said Islamabad-based analyst Amir Rana.
Haqqani was meanwhile named his "senior deputy" while Mullah Mohammad Yaqoub, the son of Mullah Omar, was once again passed over and named a simple "deputy".
"He (Akhundzada) will be a more symbolic leader than a functional leader," suggested Rana. "Maybe Haqqani will deal with the military side and Mullah Yaqoub will deal with the political affairs.
"I think he enjoys some moral supremacy among the Taliban ranks, and he is in a position to keep this consensus intact." The emergence last year of a splinter group led by Mullah Muhammad Rasool - as well as competition from the Islamic State group and former allies-turned-enemies the Islamic Movement of Uzbekistan - present a challenge to the Taliban's dominance which would have been hard to imagine in the Omar era.
Akhundzada will have to walk a fine line between hawks calling for intensified attacks in the wake of their leader's death, and more pragmatic elements seeking to negotiate a power-sharing arrangement with Kabul to end the conflict.
Yousafzai projected a rocky road ahead for Akhundzada.
"I think some other sections were not consulted, there is no unification of the movement yet, and I don't see how it can unify under Haibatullah (Akhundzada)," the analyst said.
