They are an ageless conspiracy that has existed since the dawn of time, secretly guiding the affairs of nations and peoples… but they’re also, apparently, a relatively small group of Freemasons living in or around a fairly unremarkable Bavarian town in the 1770’s, led by one Adam Weishaupt (who may or may not also have been, or have replaced, George Washington at some point).
The Bavarian Illuminati, as this group is referred to by historians for simplicity’s sake, quickly grew to a membership of over 2000 men (no women were members) by the time it was suppressed a decade later. Known members other than Weishaupt include Goethe, Ferdinand of Brunswick, Johann Gottfried Herder and the diplomat Xavier von Zwack, with numerous others speculated to be members, including most of the ruling and creative classes of southern Germany, Austria and nearby areas at the time.
It is a matter of some debate as to whether or not Betsy Ross actually created the first flag of the USA. While it is clear that she did create a design of her own which was widely used thereafter (the distinguishing feature of the Betsy Ross Flag is the arrangement of the 13 stars (or mullets, to use the heraldic term) in a circle). But the story of her creation of the flag seems to have been created from whole cloth a generation or so after the event, and there are enough loose threads in the story to make it clear that it is at least partially false (for example, Betsy Ross never met George Washington, and the records of Continental Congress show no committee to design a flag at that time).
The story of Betsy Ross seems to have been embroidered in order to address the lack of female representation in stories of the revolution, while still being an acceptably feminine role model (by the standards of the day) who would not threaten the nation’s social fabric. And for over a century, it had that role sewn up, appearing in history books as fact. It is only more recently that a generation of historians needled by the inconsistencies have cut truth from fiction.
