there were five major Patriarchs of the Roman Empire: Rome, Constantinople, Alexandria, Antioch, and Jerusalem.
By 661, Alexandria, Antioch, and Jerusalem diminished by their permanent conquest by the Islamic Arabs. after hundreds of years of ongoing battles and unrest, Constantinople finally fell to the Ottomans muslims after a two-month siege on 29 May 1453.
thus Rome was the fifth and the last surviving classical civilisation. if it had fallen to islam too, we all would be muslim or living under islam by now

These figures are a rough estimate of the death of non-Muslims by the political act of jihad.
Africa 120 million Africans
14 million africans sent to the Islamic nations of North Africa and the Middle East. For every slave captured many others died. for every slave who reached a plantation, five others were killed in the initial raid or died of illness and
privation on the forced march.[Woman’s Presbyterian Board of Missions, David Livingstone, Those who were left behind were the very young, the weak, the sick and the old. These soon died since the main providers had been
killed or enslaved. So, for 25 million slaves delivered to the market, it is estimated death of about 120 million people. Islam ran the wholesale slave trade in Africa.
Christians 60 million Christians
The number of Christians martyred by Islam is 9 million . A rough estimate by Raphael Moore in History of Asia Minor is that another 50 million died in wars by jihad.
Hindus 80 million Hindus
estimate of 80 million Hindus killed in the total jihad against India. The country of India today is only half the size of ancient India, due to jihad. The mountains near India are called the Hindu Kush, meaning the “funeral pyre of the
Buddhists 10 million Buddhists
Buddhists do not keep up with the history of war. Keep in mind that in jihad only Christians and Jews were allowed to survive as dhimmis (servants to Islam) everyone else had to convert or die. Jihad killed the Buddhists in Turkey, Afghanistan, along the Silk Route, and in India. The total is roughly 10 million.
This gives a rough estimate of 270 million killed by jihad.
