The Battle of the Coral Sea, from 4 to 8 May 1942, was a major naval battle between the Imperial Japanese Navy (IJN) and naval and air forces of the United States and Australia. Taking place in the Pacific Theatre of World War II, the battle was the first naval action in which the opposing fleets neither sighted nor fired upon one another, attacking over the horizon from aircraft carriers instead.

Tulagi, less commonly known as Tulaghi, is a small island in the Solomon Islands, just off the south coast of Ngella Sule. The town of the same name on the island was the capital of the British Solomon Islands Protectorate from 1896 to 1942 and is today the capital of the Central Province. The capital of what is now the state of Solomon Islands moved to Honiara, Guadalcanal, after World War II.
