What Were the Ten Plagues of Egypt?

According to the Old Testament story of Exodus, the 10 plagues of Egypt were a series of punishments that God visited on the Egyptians in response to the pharaoh's refusal to free the Hebrew slaves trapped in that nation; these plagues include events such as a swarm of frogs and pestilence among the country's domestic animals. Moses, a Jewish orphan who was raised in the pharoh's home, made multiple demands for the pharaoh to "let my people go," referring to pharaoh's ability to free the Hebrew slaves. When pharaoh repeatedly denies this demand, Moses warns him of the series of plagues that God will send, but pharaoh is still unmoved.
