Flag of Chad
|Design||A vertical tricolor of blue, yellow, and red. |
The flag was adopted by law #59/13 for the autonomous republic and retained on independence in 1960, and in the constitution of 1962. Despite many political upheavals within Chad since independence, the flag has not been changed. This may be because the flag is not associated with any of the main power rivals within Chad, which had no sense of national identity before independence, and little after independence. 
Blue symbolizes, officially, the sky, hope, and water; yellow the sun and the desert to the north of the country; red progress, unity, and sacrifice. Red also recalls the blood shed for independence.
