With the fading popularity of superheroes during the late 1940s, the Hawkman feature ended in the last issue of Flash Comics in 1949. In 1956, DC Comics resurrected the Flash by revamping the character with a new identity and backstory. Following the success of the new Flash, DC Comics revamped Hawkman in a similar fashion with The Brave and the Bold #34 in 1961. The Silver Age versions of Hawkman and Hawkgirl became married alien police officers from the planet Thanagar who come to Earth in order to study police techniques. Silver Age Hawkgirl is introduced as Shayera Hol (phonetically identical to Shiera Hall), who appears in costume as of her first appearance. Although Silver Age Hawkman joins the Justice League in Justice League of America #31 in 1964, Silver Age Hawkgirl was not offered membership because Justice League rules only allowed for one new member to be admitted at a time. In 1981, Silver Age Hawkgirl changed her name to Hawkwoman in the Hawkman backup feature of World's Finest Comics #274.
