Final answer:
The final chapter is called 'Peace' to denote the end of conflict and the return of stability after Odysseus reunites with his father Laertes and Athena commands peace, stopping further violence.
Step-by-step explanation:
The final chapter of The Odyssey is called "Peace" because it signifies the end of Odysseus's long struggle and the restoration of order and tranquility to his household and realm following the defeat of the suitors.
The chapter encapsulates the resolution of the epic's central conflict and the harmony that follows Odysseus's long journey home. Within the narrative, Odysseus does meet Laertes, his father, in an episodic visit
. Having vanquished the suitors who beset his kingdom and reclaimed his place, Odysseus narrates his travels to Laertes, who has been grieving his son's absence.
Together they face one final confrontation with the suitors' kin, but it's resolved with Athena's intervention, who commands peace among them, thus ending the cycle of violence and achieving the stable state implied by the chapter's title.
