The current flag and coat of arms of Singapore was adopted, six months after the island became self-governing within the British Empire.

The flag of Singapore was adopted in 1959, the year Singapore became self-governing within the British Empire. Designed by a government committee led by deputy prime minister Toh Chin Chye, it remained as the national flag upon the country's independence from Malaysia on 9 August 1965. The design is a horizontal bicolour of red above white, overlaid in the canton by a white crescent moon facing a pentagon of five small white five-pointed stars. The elements of the flag denote a young nation on the ascendant, universal brotherhood and equality, and national ideals.

The British Empire comprised the dominions, colonies, protectorates, mandates, and other territories ruled or administered by the United Kingdom and its predecessor states. It began with the overseas possessions and trading posts established by England in the late 16th and early 17th centuries, and colonisation attempts by Scotland during the 17th century. At its height in the 19th and early 20th centuries, it became the largest empire in history and, for a century, was the foremost global power. By 1913, the British Empire held sway over 412 million people, 23 percent of the world population at the time, and by 1920, it covered 35.5 million km² (13.7 million sq mi), 24 per cent of the Earth's total land area. As a result, its constitutional, legal, linguistic, and cultural legacy is widespread. At the peak of its power, it was described as "the empire on which the sun never sets", as the sun was always shining on at least one of its territories.
