Australia became independent in 1931 but remains a part of the British Commonwealth until this day. It fought on the side of the Allies in both World Wars, and the Second World War in particular left a lasting legacy on the country’s population, economy, and foreign policy. In the second half of the 20th century, Australia became one of the world’s leading industrial economies, and developed strong trading ties with its Pacific neighbors and the U.S., while maintaining its connection with its traditional partners in Europe. The White Australia Policy was gradually dismantled by 1973, which resulted in increased migration from other parts of the Asia-Pacific region, and the population has almost doubled since then. Today, Australia is one of the most highly developed nations, ranking among the top countries in terms of human development, GDP, and freedom.
