"Now, a long time ago, before there was a Galactic Republic…"
Bedran Veb[src]

The Pre-Republic Era (—25,053 BBY), also known as the Early Hyperspace Age, was the period before the formation of the Galactic Republic. It included the formation and evolution of all the species of the galaxy, the dawn of their civilizations and their first developments in space travel, and ended in approximately 25,053 BBY when the Republic was founded.
