Abdel Aziz al-Hakim was the leader of the Islamic Supreme Council of Iraq, one of the country's most powerful Shia political groups.
Al-Hakim died at the end of August after a battle with lung cancerwith many beliving his death will create a new phase for Shia Muslim politics in Iraq.
The leadership of the Islamic Supreme Council of Iraq has passed to al-Hakim's son, Ammar.
The new leader is still young in political terms and he faces tough challenges as a general election looms.
There are differences between two of Iraq's largest Shia parties - Hakim's group and the Dawa Party of Nouri al-Maliki, the Iraqi prime minister.
Efforts to rebuild the Shia parliamentary bloc have collapsed and al-Maliki's Party has been excluded from the coalition.
Many realise that such divisions jeopardise unity both within Iraq and within the Shia community.
