Why did the popes oppose commune governments in Rome and central Italy?

The popes opposed commune governments in Rome and central Italy primarily because these movements posed a direct threat to papal authority and the integrity of the Papal States.1

The emergence of the Roman commune in the 12th century was driven by a desire for freedom from episcopal and papal control, as well as a push for autonomy in managing the surrounding countryside. Because the popes sought to maintain their sovereignty over these territories, they viewed the rise of self-governing city-states—which often challenged ecclesiastical property rights and sought to tax the church—as a fundamental threat to their temporal power.21

While the popes were generally supportive of communal movements in northern Italy, they actively resisted those in central Italy and Rome itself, where such revolts directly undermined their administrative and political influence. These conflicts were often exacerbated by the popes' broader struggles against the Holy Roman Empire and the competing interests of powerful local Roman noble families.12
