Well, perhaps in the fanfiction, Dumbledore is arrested because of his ties to a certain group that the Ministry has deemed as a threat. For example, he might have been secretly helping a group of werewolves or half - bloods who are fighting for equal rights, and the prejudiced Ministry decides to arrest him to stop what they see as a subversive movement. This could lead to a great uprising within the wizarding community, with students and other professors trying to prove his innocence.
One possible plot could be that Dumbledore is framed for a crime he didn't commit. Maybe there's a dark wizard who has managed to plant false evidence against him. For example, evidence that he was involved in some sort of dark magic plot. Another could be that the Ministry of Magic, fearing his power and influence, decides to arrest him on false pretenses to gain more control over Hogwarts. This could lead to a lot of chaos in the wizarding world as Dumbledore has many allies and supporters who would not stand for his unjust arrest.
The Ministry of Magic could be responsible. They might be jealous of Dumbledore's power and popularity. They could see him as a threat to their own authority and come up with some false charges to arrest him. For example, they could claim he was hiding information about a dangerous dark wizard.
One possible scenario could be that Harry discovers some long - hidden secrets about Dumbledore that he feels were used to manipulate him. So, he might expose these secrets to the wizarding world, ruining Dumbledore's once - sterling reputation. Another could be that Harry uses his own skills and the support of his friends to undermine Dumbledore - related policies or institutions in Hogwarts that he believes were unfair.
His friends like Ron and Hermione could be his allies. They have always stood by Harry and if Harry believes that Dumbledore has wronged him, they might side with him. Ron, with his loyalty and Hermione with her intelligence could help Harry plan and execute his revenge. They could use their knowledge of magic and Hogwarts to find ways to undermine Dumbledore's influence.
A fanfiction could be about Snape's unspoken loyalty to Dumbledore. Despite their differences and the difficult tasks Dumbledore assigned him, Snape remained faithful. This could be explored through Snape's thoughts and internal monologues, showing his deep - seated respect for Dumbledore.
For Lily Potter, her husband James Potter might be a likely ally. He would support her in any conflict she has with Dumbledore. Also, her close friends from her school days could side with her. They know her well and would trust her judgment.
