Baal

Facts:

"Baal" means "lord" or "master" and was the name of the primary false god that was worshiped by the Canaanites.

There were also local false gods that had "Baal" as part of their names, such as "Baal of Peor." Sometimes all these gods together are referred to as "the Baals."
Some people had names that included the word "Baal" in them.
The worship of Baal included evil practices such as sacrificing children and using prostitutes.
At different time periods throughout their history, the Israelites also became deeply involved in Baal worship, following the example of the pagan nations around them.
During the reign of King Ahab, God's prophet Elijah set up a test to prove to the people that Baal does not exist and that Yahweh is the only true God. As a result, the prophets of Baal were destroyed and the people started worshiping Yahweh again.
