Your examples demonstrate the point, because the Persians, Arabs, and Mongols did not conquer in the colonialist model common to Western powers.

The closest would be the rapacious Mongols, who burned much and built little. That is not exactly colonialism either.

The Arabs did not really have any kind of empire to call their own until the Caliphate, and that was not colonial conquest either.

The ancient Persians invented the concept of empire, and were greatly influenced by the benign tendencies of Zoroastrianism. They preferred light taxes and light tribute, and good roads to promote trade. (For a point of comparison, when the great and mighty Rome's legions attempted to elbow in on the remnant on the Persian empire, the Parthians, the legions were utterly annihilated. Rome learned its lesson.)
