Hi,
'
Victory of the People'
can be translated as '
populi victoria' or '
victoria populi' (the position of words is flexible in Latin, since words are inflected).
However, the correct translation depends on a number of factors, such as the way you define '
people' and the position of '
victory' in the sentence.
I've assumed that you posted a fragment sentence; however, both '
populi victoria' or '
victoria populi' would work also when 'victory' is the subject of a sentence. In fact,
victoria is in the nominative case and
populi in the genitive.
