Which African country adopted a new national flag in 1994?

In 1994, South Africa adopted a new national flag, marking a significant political transformation in the country. The change occurred following the end of apartheid and the election of Nelson Mandela as the first Black president. The new flag features a unique design with a combination of colors and shapes that symbolize the country's diverse culture and the unity of its people. The use of green, yellow, black, white, red, and blue in the flag is meant to reflect the various elements of South African society. This flag represents not just a new governmental era but also a hopeful progression towards reconciliation and inclusivity after decades of division.

The other countries mentioned had established their flags prior to the events that led to South Africa's flag change in 1994. Ghana, for example, has had its flag since 1957, while Tunisia and Nigeria adopted their flags in the 20th century, long before South Africa's significant transition.
