Small borders, big personalities: 10 fun facts about the tiniest nations

In the world of geopolitics, bigger is often synonymous with more powerful, but the planet’s smallest nations prove that influence and character aren't measured in acreage. These microstates—some smaller than a city park—hold some of the most bizarre records and fascinating histories in the human story. From the "Spice Isle" of the Caribbean to a sovereign city-state tucked inside Rome, here are 10 fun facts about the world's 10 smallest countries.

Grenada is effectively the world’s spice cabinet. Despite its modest 133 square miles, it is one of the world's largest exporters of nutmeg and mace. In fact, the nutmeg is so central to the national identity that it is featured prominently on the national flag.

Also, did you know Grenada is home to the world's first underwater sculpture park? Created by British sculptor Jason deCaires Taylor, these life-sized statues are not just art; they serve as artificial reefs, providing a home for coral and marine life to combat the effects of storm damage and bleaching.

Malta, located in the heart of the Mediterranean, covers only 122 square miles but contains a density of history that is almost unmatched. For example, Malta is home to the Megalithic Temples, which are among the oldest free-standing structures in the world.

Some of these temples, like Ggantija, were built between 3600 and 3200 BC, predating the Great Pyramid of Giza and Stonehenge by centuries. It is also a favorite for Hollywood; the narrow streets of the capital, Valletta, have stood in for everything from Ancient Rome in Gladiator to King’s Landing in Game of Thrones.

The Maldives is a breathtaking chain of 1,192 coral islands in the Indian Ocean. At 116 square miles, it is the smallest country in Asia.

The Maldives also holds the record for being the flattest country in the world, with an average ground level of just 4 feet 11 inches above sea level. This makes it incredibly vulnerable to climate change. In 2009, to draw global attention to rising sea levels, the President and his cabinet held the world's first underwater cabinet meeting, signing a document while wearing full scuba gear.

Saint Kitts and Nevis is the smallest sovereign state in the Western Hemisphere, spanning 101 square miles. These two islands were the first in the Caribbean to be colonized by Europeans, earning them the nickname "The Mother Colony of the West Indies."

Another fun fact? On the island of Saint Kitts, the population of green vervet monkeys is estimated to be roughly equal to, if not greater than, the human population. Brought over as pets by 17th-century settlers, the monkeys escaped and thrived, becoming a quirky (and sometimes mischievous) staple of the island's landscape.

Tucked between Switzerland and Austria, Liechtenstein is a 62-square-mile alpine principality. While it is known as a tax haven, its biggest claim to fame is actually in your mouth. Why? Because Liechtenstein is the world's leading producer of false teeth. A company called Ivoclar Vivadent produces roughly 60 million sets of dentures annually, accounting for a staggering 20% of the global market.

Surrounded entirely by Italy, San Marino covers 23.5 square miles. It claims to be the oldest sovereign state and constitutional republic in the world, founded in 301 AD by a stonemason named Marinus.

In the 19th. century, during the American Civil War, San Marino wrote to Abraham Lincoln expressing their admiration for his leadership. Lincoln responded with a letter praising the republic’s resilience. In return, San Marino granted Lincoln honorary citizenship, a gesture he reportedly found deeply moving during one of his darkest political hours.

Tuvalu is a tiny nation of nine islands in the South Pacific, totaling just 10 square miles. Its physical existence is precarious due to rising sea levels, but its digital presence is lucrative.

Because Tuvalu was assigned the country code top-level domain ".tv," it hit a digital jackpot. The nation leases the rights to the domain to tech companies and streaming services, bringing in millions of dollars annually. This revenue accounts for about 10% of the country's total GDP, funding everything from scholarships to infrastructure.

Nauru is an island nation in Micronesia with a land area of only 8 square miles. It is the smallest island nation and the smallest republic in the world.

Nauru is the only country in the world without an official capital city. While Yaren is the largest settlement and the site of most government buildings, the nation technically lacks an official urban center. It also famously went from being the wealthiest nation per capita in the 1970s (thanks to phosphate mining) to one of the poorest after the resources were depleted.

Monaco is the world’s most densely populated country, covering only 0.75 square miles. Despite its size, it is a global icon of luxury and speed. Roughly one in every three people living in Monaco is a millionaire. The country has zero income tax, making it a magnet for the world's ultra-wealthy.

Also, Monaco’s military is actually smaller than its police force. The Compagnie des Carabiniers du Prince consists of roughly 120 soldiers, whereas the police force is over 500 strong. It is one of the few places where you could walk across the entire country in about 60 minutes.

The Vatican City is the smallest country in the world, spanning a mere 0.17 square miles (about 110 acres). It is an absolute monarchy ruled by the Pope. Despite having a population of around 800, nobody is actually born in the Vatican. The country has no hospital or maternity ward. Citizenship is not granted by birth, but rather by jus _officii_—it is given to those who work for the Holy See and is usually revoked once their service ends.

More importantly, the Vatican is the only country in the world that is, in its entirety, a UNESCO World Heritage Site. Every building, from St. Peter's Basilica to the Vatican Museums, is protected under this designation.
