Since there are relatively few simple verbs in Persian (more on this later), and since there are very few exceptions in Persian verb conjugation, one could say that learning verb conjugation in Persian is quite easy. The past simple tense, however, is even easier than the rest.

Like the English past simple tense, it states a thing that happened in the past. In Persian, each verb has two different stems and all forms of the verbs are produced using one of the two stems; present stem and past stem. The past simple, of course, uses the past stem, and is made this way:

Look at the conjugation of the verb "رفتن" (to go) in the past simple tense below to learn the six endings.

And here are some examples:

The third person singular form does not need an ending and is the same with the past stem of the verb. As you see, the infinitive of the verb is produced by adding "ن َ " to the past stem. Here are some of the most common verbs:

Here is another example of the conjugation of a verb in the past simple tense:

The stress of a past simple verb is on the last syllable of its stem. In the infinitive form, the stress is on the last syllable of the whole word. (The infinitive is actually a noun and in nouns, the stress is always on the last syllable.)

Something important to note that since the verb endings show their subjects, many Persian sentences do not contain subjects as separate nouns or pronouns (like the first and last examples above).

As we saw in the examples, verbs always come at the end of sentences, except in very special cases (like the last example.)

A list of the most common Persian verbs with their past and present stems is available here in the grammar supplements section.
