Etropus

The Etropus is an Edropian symbol particularly known for its use by the Edropian Defense Forces. It represents Edropian culture and consists of four orange triangles arranged in a circle.

Edropian Paganism (4000 BCE–18 CE)
The Etropus dates back to Edropian cave paintings from around 4000 BCE. While the origins and exact meaning are unknown, it appeared in all religious cave paintings and thus can be interpreted as the main symbol of the Edropian pagan religion. When the pagans started using clay and stone tablets around 2000 BCE, the use of the Etropus continued in religious writings. Despite its extensive use however, no official name was established as Edropian paganism was simply known as "the religion" and the Etropus as "religious symbol" in the old pagan language.

Cloacan Era (18–601)
After Edropia was annexed by the Cloacan Empire in 18 CE, the Edropian pagan religion was prohibited. As the pagans were increasingly oppressed, the Etropus became a symbol of protest, even long after the religion had gone extinct. By the 200s it started to represent Edropian nationalism and independence, and became known as the "Signum Etropus" (Cloacan: Edropian symbol), which later developed into simply Etropus with the development of Old Edropian English by the second half of the 300s. By this point the Etropus started to represent Edropian culture as a whole and played a significant role in the development of Edropian nationalism, eventually leading to Edropian independence when the Cloacan Empire collapsed in August 601.

Edropian Empire (1844–1924)
While the Etropus was widely accepted as the Symbol of Edropia throughout the next thousand years, it was rarely used by any Edropian state. It wasn't until the formation of the Edropian Empire that the Etropus saw official use, specifically in the new flag, which depicted the Etropus in the background. In 1853 the Empire designed an official modern version of the Etropus which was first used as the insignia of the Edropian Imperial Forces.

The Republic (1924–present)
The Edropian Defense Forces acted as a direct continuation of the Edropian Imperial Forces and as such directly adopted the Etropus from them. The Etropus is today used in all EDF logos but hasn't seen any other official use in the Federal Republic.
