He was one of the few within the Federalist Party who weren't corrupted.
—Jane Zarkan II to Annabelle Nakamura
Jax Horain was a human male born on Earth.
In 83 BBY, he began to write the Articles of Union and by 81 BBY, they served as the founding document of the Union of Earth States, a government which that united all of Earth's nations and governments into single-ruling government. Jax served as the first Union President until the 72 BBY election, succeeded by Monique. Before serving as Union President, he also served as Prime Minister of Nortalia, a title of the elected leader for Nortalia.
He died of old age in 61 BBY. To commemorate his service and achievement of brining Earth together, Union President Alice Ward commissioned for a statue to be built in the government's capital, which depicted him holding the Articles of Union in his hands. The Federalist Party considered it merely as a memento, despite that Jax was once their leader.
