YOU CAN THANK ME LATER!!!!!!
The objection that the iconoclasts had to a painting such as this one is that the image promotes worship of Mary over God.
Based on the image, it would seem that Mary is far more important in Christian religion according to what she looks like, and where she is sitting, and that baby Jesus is not as relevant as she is. Iconoclasts were a group of people who wanted to destroy religious icons anyways.
They (as in the poor and lower class) began to question the rights of the Caliphs to be ruling/guiding them. There was negligence in the government and no one was running it properly allowing for the Turks to gain the upper hand causing riots not to mention Muslims and non Muslims were clashing ideas. The empire got to big and out of hand for anyone to control.
As far as the reports say, just one and it was the one that carried JFK to the hospital, Parkland, where he later died in a trauma room.
Hope this helps! :)
