Affected vs Effected

Affected and Effected are both verb forms.

When used as a verb, effect means to execute, produce, or accomplish something. For example, The dictatorial regime quickly effected changes to the constitution that restricted the freedom of the people.

On the other hand, affect in its verb form means to impact. For example, Carbon di-oxide emissions affect the environment.

So we can say that "The dictatorial regime quickly effected changes to the constitution that affected the freedom of the people."
