The trial of deposed president Mohamed Morsi and 14 senior Islamist and Muslim Brotherhood leaders started at the Police Academy in New Cairo shortly before 11am on Monday morning.
Names of the defendants have been called as they stood inside the cage box, reported Al-Ahram Arabic news website.
The defendants are charged with incitement of murder and violence at the Ittihadiya presidential palace clashes in December 2012.
At least ten died in the clashes, which broke out after pro-Morsi protesters attacked a sit-in held by opponents of a presidential decree which had granted the Islamist leader expanded powers.
