The story of Pharaoh's death in the Red Sea is a biblical account found in the Book of Exodus, where the Pharaoh pursues the Israelites as they escape from slavery in Egypt. When the waters of the Red Sea are parted for the Israelites to cross and then return, the Pharaoh and his army are drowned.
The Bible does not specify who became king of Egypt after this event. Historically, there are gaps in the record of Egypt's leadership during this period, and the exact timeline of subsequent Pharaohs is not clearly defined in biblical texts. After the Exodus, the Egyptians likely continued to have a succession of Pharaohs, but their names and the details of their reigns are not explicitly recorded in the biblical narrative. For more accurate historical context, one would need to refer to archaeological or historical sources concerning Egypt's history during that era.
