The Serene Sanctuary of The Holy Principality of Saint Mark is a gargantuan, cultured nation, ruled by His Serene Highness Prince Marcarius with a fair hand, and notable for its museums and concert halls, deadly medical pandemics, and otherworldly petting zoo. The compassionate, hard-working, democratic, cheerful, devout population of 13.066 billion Saint Markans live in a state of perpetual fear, as a complete breakdown of social order has led to the rise of order through biker gangs.

The relatively small, pro-business government is primarily concerned with Education, although Industry, Environment, and Spirituality are also considered important, while Social Policy is ignored. It meets to discuss matters of state in the capital city of Sanctus Leo. Citizens pay a flat income tax of 46.5%.

The frighteningly efficient Saint Markan economy, worth a remarkable 4,374 trillion Marks a year, is broadly diversified and led by the Tourism industry, with major contributions from Information Technology, Retail, and Book Publishing. Average income is an amazing 334,797 Marks, but there is an enormous disparity between incomes, with the richest 10% of citizens earning 2,006,985 per year while the poor average 25,318, a ratio of 79.3 to 1.

His Serene Highness Prince Marcarius's office has a newly installed Max-Man arcade game programmed by a 5th-grader, Jennifer Government is a bestseller, the latest Harry Potter book is a bestseller, and nude art is becoming wildly popular. Crime is totally unknown. The Holy Principality of Saint Mark's national animal is the Lion, which is also the nation's favorite main course, and its national religion is Christianity.

The Holy Principality of Saint Mark is ranked 2,639^th in the world and 44^th in the West Pacific for Most Efficient Economies, scoring 100.5 on the Krugman-Greenspan Business Outlook Index.
