Brutus was also a pseudonym used by the "anti-federalists" early in the history of the United States. The "anti-federalists" as their name implies wanted a less centralized government where individual states would have more power.

Rather than publish opinions under their own name, the framers of the constitution sent essays anonymously to local newspapers to convince the public that their way was better. Alexander Hamilton and James Madison, most famously, published under the pen name "Publius" what became the "Federalist" (commonly called "the Federalist Papers") later with John Jay.
