Kingdom of Eswatini (independent)
Who & why: Swaziland becomes independent on 6 September 1968 under King Sobhuza II, who reigns until 1982 (one of the longest verified reigns of any monarch in history). His son King Mswati III, on the throne since 1986, renames the country Eswatini ("land of the Swazis") in 2018 to mark 50 years of independence and to avoid confusion with Switzerland. The kingdom remains an absolute monarchy today, with political parties banned from standing in elections and the king holding final authority over government, a system that has drawn sustained pro-democracy protest movements in recent years.
What it represents: based on a banner presented to Swazi soldiers who served in the British Army during the Second World War, blue for peace, yellow for the country's mineral wealth, and red for past conflicts; the black-and-white Nguni cowhide shield, spears, and staff represent the monarchy's protective authority over the nation.
