In Trollope's novel, Britannula is a former British Crown Colony which demanded, and was granted, independence from Great Britain in the mid-20th century. Its 250,000 inhabitants have, with few exceptions, retained British law and customs, and also her currency. Britannula is a thriving agrarian society whose wealth is mainly based on sheep farming and the wool trade. Its capital, Gladstonopolis, is named after 19th century British Liberal statesman and Prime Minister William Ewart Gladstone.
