The Republic of Amestris-Britannia is a gargantuan, cultured nation, ruled by President of the Central Council with an even hand, and renowned for its museums and concert halls, frequent executions, and daily referendums. The compassionate population of 14.921 billion Amestris-Britannians have some civil rights, but not too many, enjoy the freedom to spend their money however they like, to a point, and take part in free and open elections, although not too often.

The enormous government juggles the competing demands of Healthcare, Education, and Environment. It meets to discuss matters of state in the capital city of Amestris. The average income tax rate is 85.0%, and even higher for the wealthy.

The frighteningly efficient Amestris-Britannian economy, worth a remarkable 1,236 trillion Pounds a year, is highly specialized and mostly made up of the Information Technology industry, with significant contributions from Book Publishing. State-owned companies are reasonably common. Average income is 82,887 Pounds, and distributed extremely evenly, with little difference between the richest and poorest citizens.

Political candidates must be personally vetted by President of the Central Council, buses are widely regarded as the safest way to travel, board shorts have replaced board rooms, and increasing inclusiveness is a sign of the times. Crime is totally unknown, thanks to a very well-funded police force and progressive social policies in education and welfare. Amestris-Britannia's national animal is the Fox, which frolics freely in the nation's many lush forests.

Amestris-Britannia is ranked 274,971^st in the world and 5,584^th in The North Pacific for Most Extreme, scoring 6.98 on the Paul-Nader Subjective Decentrality Index.
