The Persian Civilization

There was a time when ancient Persian civilization (now Iran) was in fact the most powerful empires in the world.
Even though its power lasted for a little over 200 years,
the Persians conquered lands that covered over 2 million square miles.
From the southern portions of Egypt to parts of Greece and then east to parts of India,
the Persian Empire was known for its military strength and wise rulers. Before 550 BC,
Persian (or Persis as it was called back then) used to have a number of leaders.
Each used to rule different regions.

But later King Cyrus II, (or as Cyrus the Great) came into power and unified the entire Persian Kingdom.
Then he went on to conquer the ancient Babylon.
In fact, his conquest is so rapid that until the end of 533 BC, he already invaded India, far in the east.
And even when Cyrus passed away, his bloodline continued the ruthless expansion,
and even dueled in now legendary battle with the brave Spartans.
At its prime, ancient Persia ruled all over central Asia, much of Europe and Egypt.
But it all changed when the legendary soldier of Macedon, Alexander the Great,
brought the whole Persian empire down to its knees and effectively ended the civilization in 530 BC.
