Surprisingly, today the most powerful tool of propaganda is cinematography. Promotion of an idea, be it false or true, good or evil, is very easy, and that easiness impresses and frightens everyone, including historians and people familiar with history.
That is the reason for the high value of films made by specialists to tell information based upon fact and knowledge. On the contrary, films made for entertainment might distort history, though it may be not for sake of propaganda but simplicity, views and profits.
For instance, Alexander III of Macedon, a king of the Ancient Greek kingdom of Macedon, was an extraordinary politician and man of arms, deeply educated by his mentors.
He created one of the largest empires of the ancient world by the age of thirty, stretching from Greece to northwestern India. He was undefeated in battle and is widely considered one of history’s most successful military commanders.
There have been some films about the great king. But no one of them featured another kingdom of the ancient world, Armenia. Alexander the Great’s activity somewhat directly resulted in the establishment of Armenian Orontid dynasty in the newborn kingdom of Armenia, which is a very interesting topic for Armenian audience.
