It was called democratic because it is based on the principles of democracy, which is a system of government in which the power is held by the people, either directly or through elected representatives.
In a democratic system, citizens have the right to participate in the decision-making process, either through direct voting or through the election of representatives who will make decisions on their behalf. The term "democratic" is often used to describe a society or a system of government that is characterized by fairness, equality, and the protection of individual rights and freedoms.
