Sudan
Red, white, black and green are called the pan-Arab colours and have been historically linked to the Arab people and Islamic religion for centuries. The colours stand for Arab unity and independence. The red stripe represents Sudan’s struggle for independence and many other struggles, and the sacrifices of the country’s martyrs. The white represents the people, light and optimism. It also represents the White Flag League which was a nationalist group that rose up against colonial rule in 1924. The black represents Sudan; in Arabic, ‘Sudan,’ means ‘land of the black people.’ It also represents the black flag of nationalists who fought colonial rule during the Mahdist Revolution, late in 19th century. Green represents Islam, agriculture and the prosperity of the land.[
