Christening (also known as baptism) was a ritual performed to admit a person into the Christian faith, typically involving the pouring of water on the forehead, or full or partial immersion of the body in water.
The christening of Harry Potter was held at the height of the First Wizarding War in 1980 or 1981, and was a "very hurried, quiet affair" featuring only Harry's parents, James and Lily Potter, and their best friend, Sirius Black.
