Occupying just 24 sq mi (62 sq km), San Marino is the world’s smallest republic and, having enacted a constitution in 1600, perhaps Europe’s oldest existing republic.

Because of its relatively inaccessible location, it has since maintained its independence with only a few brief interruptions. Who did San Marino harbor during WWII? Discuss
