The flag of Eswatini was adopted on 6 October 1968[1] after Eswatini (then known as Swaziland) gained its independence from the United Kingdom one month before. The design by King Sobhuza II features a black and white shield called the Nguni shield, with a staff and two spears, on a field of blue, yellow, and red horizontal bands.

The flag is based on the military flag given by King Sobhuza II to the Swazi Pioneer Corps in 1941 to remind them of the nation's military traditions. On 25 April 1967, the day the pledge of oath was taken by the king, the flag was hoisted for the first time. The College of Arms in London registered the flag on 30 October 1967. The first official hoisting of the flag was conducted on this day.

The flag is rectangular with length and breadth in a ratio of 3:2 respectively. The red stands for past battles, the blue for peace and stability, and the yellow for the resources of Eswatini. The central focus of the flag is a Nguni shield and two spears, symbolising protection from the country's enemies. Its colour is meant to show that white and black people live in peaceful coexistence in Eswatini. Wikipedia
