The cosmopolites are literally "citizens of the world," from the Greek word kosmos, meaning "world," and polites, or "citizen." Garry Davis, aka World Citizen No. 1, and creator of the World Passport, was a former Broadway actor and World War II bomber pilot who renounced his American citizenship in 1948 as a form of protest against nationalism, sovereign borders, and war. Today there are cosmopolites of all stripes, rich or poor, intentional or unwitting, from 1-percenters who own five passports thanks to tax-havens to the Bidoon, the stateless people of countries like the United Arab Emirates. Journalist Atossa Abrahamian, herself a cosmopolite, travels around the globe to meet the people who have come to embody an increasingly fluid, borderless world.

Along the way you are introduced to a colorful cast of characters, including passport-burning atheist hackers, the new Knights of Malta, California libertarian "seasteaders," who are residents of floating city-states, Bidoons, who have been forced to be citizens of the island nation Comoros, entrepreneurs in the business of buying and selling passports, cosmopolites who live on a luxury cruise ship called The World, and shady businessmen with ties to Syrian dictator Bashar al Assad.
