How did Crisis on Infinite Earths change Wonder Woman's comic-book continuity?

The Crisis on Infinite Earths series (1985–1986) was launched by DC to resolve decades of convoluted continuity, which had previously separated Wonder Woman into two distinct versions: an Earth-Two version associated with the 1940s and the Justice Society, and an Earth-One version associated with the Justice League.1

Following the series, the DC universe was "reset" to feature only one Earth and a single version of every hero. In February 1987, a grand relaunch of the Wonder Woman title established a new continuity with several key changes:

• Mythological Focus: The backstory of the Amazons and the involvement of Greek gods became central to her origin.1
• Role and Identity: Diana was established as an ambassador from Themyscira to the world, tasked with teaching lessons of peace and love, and she no longer maintained a secret identity.1
• Origin Details: Her origin was updated to include her winning a tournament to become the champion of the Amazons against the war god Ares, and her costume was reimagined as being inspired by Diana Trevor, a female aviator known to the Amazons.1
