Answer: Most modern political systems are constitutional, not autocratic.
Explanation: The constitutional or non-autocratic systems are characterised by the group of several centres consisting of many people, who have a share in the exercise of power. This strengthens social forces which promote the freedom of a variety of interests and opinions. The power holders do not assume complete dominance and hence the power is reciprocated, ensuring the effective sanctions of law.
This is not promoted in Autocracy, as the power lies in the hands of a single centre, which can be a dictator or a small group of people. this can lead to the suppression of opposition or even the development of the country as a whole.
