He will enter Europe wearing a blue turban.
He will be the terror of mankind.
Never more horror.

Here, Nostradamus says that a man from Greater Arabia will lead his forces on an invasion through Europe. This invasion will start a third world war that will be far worse than all the other wars put together. When will all this take place? In one quatrain Nostradamus gives us an exact date in which the war will be well under way.
In the year 1999 and seven months
From the sky will come the great King of Terror.
He will bring back to life the King of the Mongols;
Before and after war reigns.
