In the 1980s, for the first time since 1945, two governments were led by non-Christian-Democrat premiers: one republican (Giovanni Spadolini) and one socialist (Bettino Craxi); the Christian Democrats remained, however, the main government party. During Craxi's government, the economy recovered and Italy became the world's fifth-largest industrial nation after it gained the entry into the Group of Seven in the 1970s. However, as a result of his spending policies, the Italian national debt skyrocketed during the Craxi era, soon passing 100% of the country's GDP.
