The man who built up the Jamaat-e-Islami in Bangladesh on the lines of Syed Abul A'la Maududi is now consigned to prison for the rest of his life.
Maududi was convicted and sentenced to death by a court in Pakistan for inciting religious passions but later pardoned.
Azam has not been so lucky.
Scholars say that Maududi’s teachings severely contradict the key tenets of Islam, despite his claims to be a leading Islamic thinker.
That is why many Islamic groups in Bangladesh are stridently opposed to the Jamaat-e-Islami.
Ghulam Azam, a close follower of Maududi, was the chief of East Pakistan Jamaat-e-Islami during the 1971 Liberation War.
But human rights worker Sultana Kamal says Azam was as cruel as Hitler.
After the assassination of founding father Bangabandhu Sheikh Mujibur Rahman, Ghulam Azam returned to the country with a Pakistani passport in 1978 on the pretext of visiting his sick mother.
After three months Azam’s visa expired but he never left Bangladesh.
‘Ghatak Dalal Nirmul Committee’ leader Shahriar Kabir says many groups had protested against Azam's decision to stay on but the country's first military ruler Ziaur Rahman did not pay heed to their concerns.
Azam was restricted in his movements, though, and in 1981 he was publicly struck with shoes at Baitul Mukarram National Mosque.
After a decade in 1991, Jamaat-e-Islami declared Ghulam Azam as its chief, provoking a furore.
A movement fronted by 'Shahid Janani' Jahanara Imam led to his arrest on Mar 28, 1992.
The People’s Court 'Gana-Adalat' organised by Imam sentenced the Jamaat-e-Islami chief to death.
A prominent 'Gana-Adalat' organiser Shahriar Kabir said, “When Jahanara Imam was reading out the verdict of charges of war crimes and crimes against humanity the people shouted ‘hang him’, ‘hang him’. It reverberated through million voices.”
But Ghulam Azam filed a writ petition at the High Court in 1998 and the court reinstated his citizenship.
The verdict provided him with citizenship but it did mention his allegiance to Pakistan during the 1971 war.
The demand to bring Ghulam Azam to justice has never died down.
Ghulam Azam retired from active politics in 1999, but he retained a strong influence in the party.
The Awami League initiated the process to try war criminals after they came to power in the December 2008 elections.
Ghulam Azam was arrested in Jan 12, 2012. He was kept at Bangabandhu Sheikh Mujib Medical University due to his age and fragile health.
