Chicago’s South Side was solidly working class during Pope Leo’s childhood, said Rob Paral, a researcher at the Great Cities Institute at the University of Illinois Chicago. The family attended a South Side church, but they lived in Dolton, a suburb just past the city line.

The new Chicago-raised Pope Leo XIV faces an immediate challenge in his native country: taming the brawling U.S. tribe of Catholics, riven by political divisions that have thwarted the will of his predecessors.
