Besides creating the judicial branch, article iii speaks of what important right of the people?

Besides creating the judicial Branch, “The judicial power of the United States, shall be vested in one Supreme Court”, the Third article of the U.S Constitutions states in its Second Section that “The trial of all crimes, except in cases of impeachment, shall be by jury; and such trial shall be held in the state where the said crimes shall have been committed.”

So the answer to your question is:

The important right of the people that the third article speaks of is: “the trial of all crimes, except those of high treason or impeachment, shall be by jury.

explanation: we can only guess at how our actions may be perceived in the future. doing something really big like killing lots of people, saving lots of people, affecting the lives of lots of people is a sure fire way of being remembered in historical records. we can also make a difference in the history records by being a small influence on something bigger, whether that is as a civil servant, scientist or artist.

of course you could argue that we all affect history just as tiny cogs in a   bigger machine.

if you mean how do people influence our opinions of things which have already happened, then simply by writing a book which looks at things form a different perspective and trying to convince people that this perspective is more accurate or truthful. people do it all the time i.e. richard the third was a terrible or was he? plenty would disagree, it's just that their views aren't the most widely known.n:
