'Diktieren' (to dictate) is the basis for the nouns 'das Diktat' (a dictation; a text that is dictated) and 'der Diktator' (dictator; a person who dictates orders). All these words share the idea of saying or commanding.

The verb 'diktieren' (to dictate) is very often used with two objects: the person to whom something is dictated is in the dative, and the thing that is dictated is in the accusative. The pattern is: Jemand diktiert [jemandem] [etwas]. (Someone dictates [something] to [someone].)

In the literal meaning, a text, a sentence, a number, or a letter is often dictated. You can also dictate something to someone 'in den Block' (into the notepad) or 'in die Feder' (literally: into the pen).

When 'diktieren' (to dictate) is used in connection with politics, history, or negotiations, it means 'aufzwingen' (to impose) or 'befehlen' (to command). Typical objects here are abstract things like conditions, rules, or a peace treaty.

You cannot always choose the conditions; sometimes they are dictated to you.
In a figurative meaning, abstract things like 'die Mode' (fashion), 'der Markt' (the market), or 'die Logik' (logic) can also dictate something. The subject is then not a person, but a concept that determines something.

to prescribe / write out
Vorschreiben and diktieren can both mean that conditions are set unilaterally. Vorschreiben refers to a binding rule or instruction. Diktieren places greater emphasis on someone using their power to impose conditions on others in an authoritarian way.
