Quoting the same encyclopedia entry:

The Anti-Federalists saw the primary task of government as securing individual liberty. They also recognized that the cultivation of republican virtues was necessary for liberty, and believed that such cultivation would fare better in a small, homogenous republic.

In one of the more interesting ironies of American history, the Anti-Federalists were the true Federalists, since they supported a “federal” system as the late 18th century Americans understood the term.
