When did the Arab Caliphate flourish under Harun al-Rashid?

In 768, the reign of Harun al – Rashid began and lasted for 23 years. Under his rule, the state became one of the most developed caliphates. Economy, culture, science flourished. Centuries later, descendants recognized in the hero of the “Thousand and One Nights” the ruler of ancient Baghdad. The author has embellished the true character traits of Harun al – Rashid. The patron saint of scientists, artists, in reality, was a cruel, ambitious ruler. Erected to the throne by his Iranian mother, he was an implacable opponent of people of other faiths. Christian churches were destroyed and gentiles were oppressed. Subsequently, all advisors were removed and his best friend was killed. Harun became the sovereign ruler of Baghdad. Even during his lifetime, the rudiments of the disintegration of the state were outlined and it was divided between his sons.
