What prophecies truly came to pass?

Whoever opens my tomb will let loose a monster worse than I am.

That was the phrase carved on the tomb of Genghis Khan's most deserving successor, the terrifying Tamerlane, who terrorised the Middle East and South Western Asia. In his lifetime, he slaughtered nearly 17 million people while ruling over an empire that covered 4.4 million square miles, which is comparable to the size of the Roman Empire at its height.

Tamerlane's tomb caught Joseph Stalin's attention in 1941, and he dispatched an archaeological team to Samarkand, Uzbekistan, to investigate. They visited his tomb despite the inscription. A few hours later, Adolf Hitler sent 3 million troops into Stalin's USSR for the largest land invasion in history, which resulted in the deaths of almost 26 million Russians.

Interesting enough, the German 6th army was destroyed at Stalingrad when Stalin purportedly ordered Tamerlane's tomb to be resealed, essentially eliminating all hope for a German victory.
