Most of the 80,000 who attended the conference were Indonesian
Some 80,000 Islamists have met in the Indonesian capital, Jakarta, to press for the re-establishment of a caliphate across the Muslim world.
The Islamist group Hizb ut-Tahrir - which organised the conference - said it had been the largest gathering of Muslim activists from around the world.
However, the group is illegal in many countries and key speakers have been stopped from entering Indonesia.
A caliphate - or single state for Muslims - last existed in 1924.
Hizb ut-Tahrir regards this as the ideal form of government, because it follows what it believes are the laws of God as set out in the Koran, rather than laws designed by man.
