No, they didn't.
No that's Constantine
As far as I am aware Islam does not have a single spiritual leader, in the same way that Christianity has the Pope. Until the end of the Ottoman Empire (1918) the sultan of the Ottoman Empire was the de facto spiritual leader of Islam.
The Bishop of Rome was the head of Latin or western Christianity in the last few centuries of the Roman Empire, in the the days when Christianity became the state religion of this empire. Latin Christianity was the main form of Christianity in the western part of the Roman Empire. Greek or Eastern Christianity was the main form of Christianity in the eastern part of the empire. Later they came to be called Catholic and Orthodox respectively. Therefore, the Bishop of Rome was the spiritual leader of the Christians in the western part of the empire. Later the bishop of Rome also took on the title of Pope.
Most historians of this era agree Christianity was established as the official religion of Rome by the Roman Emperor Constantine in 313 AD.
In the last 300 years of the Roman Empire Christians were imprisoned and tortured. When the Emperor Constantine I the Great was ruling the Roman Empire Christianity was adopted as the state religion and transferred the capital to the Eastern part of his Empire and named the city New Rome [later Constantinople]. For 10 centuries Christianity was united. In the year 1054 dogmatic differences separated the Christian Church to the Western Roman Church with the Pope as leader and the East Orthodox Church with the Patriarch of Constantinople as leader.
The title of the world leader of the main religion Christianity is The Pope.
Akbar was the great leader of the Mogul Empire.
If you mean the ancient city of Rome, it has always been the Bishop of Rome, (the title of Pope was added later). In the Roman days he was the leader of what was called Latin or Western Christianity (now it is called Catholic Christianity). If you are referring to the Roman Empire, there were five leaders of Christianity, the patriarchs. One of them was the Bishop of Rome. The others were the patriarchs of what was then called Greek or Eastern Christianity (now it is called Orthodox Christianity). They were the patriarchs of Constantinople, Antioch, Jerusalem and Alexandria.
The leader was Esma'il.
Pope.
Jesus!
