Fascism conceives of the State as an absolute, in comparison with which all individuals or groups are relative, only to be conceived in their relation to the State.
If the 19th [century] was the century of the individual (liberalism means individualism), you may consider that this is the "collective" century, and therefore the century of the state.
The keystone of the Fascist doctrine is its conception of the State, of its essence, its functions, and its aims. For Fascism the State is absolute, individuals and groups relative.
