Most of Disney’s animated classics take place in an idyllic past, and so, of course, there are a number of Disney movies based on historical events. But the history lessons don't stop there. Disney filmmakers not only put their spin on antiquity, but also fill films with Easter eggs, double entendres, and other historical references most children miss, but adults can surely appreciate.
Typically, these allusions and analogues are included to add an extra layer of authenticity and accuracy to the worlds Disney creates on screen. Learning something along the way is a nice added bonus.
