Tiny nations with outsized stories — explore the world's most miniature sovereignties
Vatican City is the world's smallest country at just 0.44 square kilometers with approximately 800 residents. This 50-question quiz takes a deep dive into the world's tiniest sovereign nations — from the oldest republic on Earth (San Marino, founded in 301 AD) and Monaco's jaw-dropping population density of 26,000+ per square kilometre, to Nauru's rise and fall as a phosphate island paradise and Tuvalu's ingenious revenue from its .tv internet domain. These microstates may be small in size, but their stories are anything but.
The world's smallest countries prove that size is no barrier to sovereignty, wealth, or fascinating history. Vatican City fits inside a few city blocks yet leads a church of 1.3 billion people. Monaco squeezes 26,000 residents into each square kilometre while boasting the world's highest GDP per capita. San Marino has survived as an independent republic since 301 AD. These tiny nations punch far above their weight on the world stage.
Each round presents 10 randomized multiple-choice questions drawn from a pool of 50, so every playthrough is different. You get instant feedback with explanations after each answer, plus a shareable score at the end.
You'll explore Vatican City's 0.44 km² of religious power, Monaco's extraordinary density, San Marino's claim as the oldest republic, Liechtenstein's surprising wealth from false teeth exports, Nauru's phosphate boom and bust, Tuvalu's ingenious .tv domain deal, and many more stories from the world's most miniature sovereignties.
Vatican City is the world's smallest country at just 0.44 square kilometres. Located within Rome, it became independent through the Lateran Treaty of 1929 and serves as the spiritual and administrative center of the Roman Catholic Church.
San Marino claims to be the world's oldest republic, founded on September 3, 301 AD by a stonemason named Marinus. At 61 square kilometres, it is entirely surrounded by Italy and has maintained its independence for over 1,700 years.
Tuvalu's .tv country code domain became valuable because it matches the television abbreviation. In 2000, Tuvalu leased the domain rights for $50 million over 12 years, providing crucial revenue for this tiny Pacific nation of about 11,000 people.
