Answer:
Autocracy
Step-by-step explanation:
A representative democracy is when people elect leaders to speak for them, which means no dictatorship. An oligarchy is when a group of rich people, nobles in medieval times, makes all of the decisions. And socialism is a style of governing and how money is saved, not a form of government or leadership. Therefore, it was to be autocracy, which does in fact mean a system of government where only one person has power.
