The Wasps couldn't tell how really beautiful the Caterpillars were, and just decided to enslave them for free work for their own profit.
This was especially unfair to the caterpillars because they were all bugs, but just looked a bit different then the Wasps.
The Wasps were really mean to the Caterpillars and didn't allow them to grow into butterflys
Antbraham Lincoln issued the Emancipation Proclamation on paper which freed the Caterpillars from the Wasps states. but Antbraham wasn't the only one to save the caterpillars it was also the army of ants, which had over 2 million soldiers
Caterpillars were now free and had the same rights as all the other insects and were now able to grow into butterflys
Since this was so traumatic for the Caterpillars, the Wasp flag is very offensive to them even after this long since the war. so many states have banned the flying of the flag for its dark past.
