The main characteristic of the imperative is to exist only to the following persons: "tu", "nous" and "vous". It allows you to express an order, give advice or make a suggestion. The past imperative makes it possible to introduce a notion of anteriority before another action. As much to say it immediately, the imperative past is of a very rare use.
Aie rangé tes affaires quand j'arrive.
In order to be able to form the past of the imperative, you must know how to conjugate the auxiliaries "avoir" and "être" in the present of the imperative and know how to form the past participle. The main difficulties of the imperative past come from its rather rare use and ending with the past participle.
