Jar Jar Binks, the Gungan from Naboo, is a character whose fate after the rise of the Galactic Empire is both tragic and reflective of the turbulent times in the Star Wars galaxy. While the films and animated series provided significant glimpses into his early life and involvement in the Clone Wars, the details of his life following Order 66 are primarily derived from Star Wars Expanded Universe materials, now classified as Legends, and some canon sources. Here is a comprehensive account of what happened to Jar Jar Binks after Order 66:

Immediate Aftermath of Order 66
Order 66, a command issued by Emperor Palpatine to eliminate the Jedi Order, marked a significant turning point in the Star Wars saga. As the Jedi were hunted down and the Galactic Empire rose to power, many former allies of the Jedi and the Republic found themselves in precarious positions. Jar Jar Binks, who had been manipulated into proposing emergency powers for Palpatine, indirectly contributing to the fall of the Republic, faced severe backlash.

Attending Padmé's Funeral
One of the earliest events following Order 66 that involved Jar Jar was his attendance at Padmé Amidala’s funeral on Naboo. Padmé, a close friend and ally, had died under mysterious circumstances. In the film "Star Wars: Episode III – Revenge of the Sith," Jar Jar is seen mourning at her funeral procession. This scene underscores his deep connection to Padmé and the emotional impact of her death on him.

Fall from Political Grace
Jar Jar’s political career, once buoyed by his role as a senator, plummeted after the formation of the Empire. His decision to propose granting emergency powers to Palpatine, initially seen as a necessary wartime measure, became a source of widespread resentment. Both the Gungans and the human population of Naboo held Jar Jar partly responsible for the rise of the oppressive Empire. This sentiment effectively ended his political career and left him ostracized from the very society he had once served.

Life on Naboo
Following his political downfall, Jar Jar returned to Naboo. His homecoming was not met with open arms. Many on Naboo viewed him as a symbol of the Republic's failure and the Empire's rise. This scorn was particularly harsh among the Gungans, who felt betrayed by one of their own. The once-respected representative now found himself a pariah.

"Aftermath: Empire's End"
Jar Jar’s later life is depicted in the novel "Aftermath: Empire’s End" by Chuck Wendig. The book provides a poignant look at his post-political life. In this story, Jar Jar is described as a street performer in the capital city of Theed. He entertains children with his antics, bringing laughter to their faces. However, his presence is largely ignored or avoided by adults who remember his role in the rise of the Empire. This situation is emblematic of Jar Jar’s fall from grace; he is relegated to performing for the amusement of children, far from the halls of power he once walked.

In the novel, Jar Jar meets a young boy named Mapo, who is also an outcast. Their interaction is touching and reveals Jar Jar’s enduring kindness and empathy despite his circumstances. He teaches Mapo some tricks and offers him companionship, showing that even in his reduced state, Jar Jar continues to exhibit the good-natured qualities that defined him.

The Open-Ended Fate
The narrative in "Aftermath: Empire's End" is the last canonical mention of Jar Jar Binks. His ultimate fate remains unknown, and no official records exist detailing his death. This open-ended conclusion leaves his story with a sense of unresolved tragedy. While many characters in the Star Wars universe have clear beginnings and endings, Jar Jar’s story is one of ongoing ambiguity.

Legacy and Impact
Jar Jar Binks’ legacy is multifaceted. On one hand, he is remembered as the bumbling yet well-intentioned Gungan who played a crucial role in pivotal moments of the Republic’s history. On the other hand, he is seen as a tragic figure whose actions inadvertently contributed to the rise of the Empire. His story serves as a reminder of the complexities of political decisions and their far-reaching consequences.

Expanded Universe (Legends)
In the Star Wars Legends continuity, which includes materials that are no longer considered canon, Jar Jar’s story after Order 66 is less fleshed out. Various speculative and fan-driven narratives exist, but none are officially recognized by Lucasfilm’s current Star Wars canon.
