The Kingdom of Tyrell is a mammoth, socially progressive nation, ruled by Lord Willas Tyrell with a fair hand, and notable for its barren, inhospitable landscape, compulsory military service, and zero percent divorce rate. The hard-working, democratic, devout population of 8.286 billion Tyrells enjoy a sensible mix of personal and economic freedoms, while the political process is open and the people's right to vote held sacrosanct.

The relatively small government juggles the competing demands of Spirituality, Welfare, and Defense. It meets to discuss matters of state in the capital city of Highgarden. The average income tax rate is 9.9%.

The strong Tyrell economy, worth 526 trillion gold hands a year, is broadly diversified and led by the Arms Manufacturing industry, with major contributions from Woodchip Exports, Basket Weaving, and Uranium Mining. Average income is 63,601 gold hands, and evenly distributed, with the richest citizens earning only 4.5 times as much as the poorest.

Fire and brimstone sermons are accompanied by napalm and fragmentation bombs, tax avoidance is a serious affair, lifeguards are more concerned with watching for sharks than struggling swimmers, and criminals rejoice in the streets as the entire police force is sent away on a training retreat. Crime, especially youth-related, is totally unknown. Tyrell's national animal is the fox, which can occasionally be seen sifting through garbage in the nation's cities, and its national religion is Faith of the Seven.

Tyrell is ranked 142,180^th in the world and 23^rd in Westeros for Most Developed, scoring 56.25 on the Human Development Index.
