In the dictionary, a diktat is defined as an order that is harsh and unilaterally imposed on a people without their permission. It is usually used with the connotation of being issued to a defeated country or people. A dictate is simply a command or order, without the necessity of being harsh.
The most common place to hear or read the word diktat is India, where it is used for orders which come from military or faith leaders. It still carries its pejorative connotation.
Originally, diktat came from the German language.
