The 1963 law specifies the flag’s geometry
The law defines the national emblem as a green-and-white flag bearing a red star and crescent. Its technical annex sets the rectangle’s length at one and a half times its height and divides the field into two equal vertical halves: green next to the hoist and white at the fly.
The same annex sets technical characteristics for the colours and gives construction details for the star and crescent. These legal specifications describe appearance and placement; the text does not assign a separate official meaning to each colour or shape.
The preamble calls the flag a symbol of national sovereignty
The law’s preamble describes the flag as a symbol of national sovereignty. It says the emblem already existed and had been adopted by Algerians during the struggle for independence, before the state gave it an official technical definition.
That account distinguishes recognition from creation: the law formalized an emblem already in use. It does not identify a single date when the design first appeared, nor does it turn popular explanations of green, white, the star or the crescent into legal definitions.
A statute formalized the emblem after independence
Law No. 63-145 was promulgated in Algiers on 25 April 1963, after Algeria became independent. Article 1 names the green and white colours and the red star and crescent; Article 2 refers readers to the annex for the technical details.
The annex then specifies the proportions, division of the field, colour characteristics and emblem construction. Keeping the article and annex together makes clear which points are legal requirements and which symbolic interpretations are not stated in the law.

About historical flags
Vexilla's historical flag collection includes former flags associated with present-day countries and territories, as well as flags of states, empires, and other authorities that historically governed them.
A flag's inclusion in a country's historical collection does not necessarily mean that the country was independent at the time or that the flag was its own national flag.
The years shown are based on historical records in the dataset and do not always indicate the date of official adoption. The collection is not exhaustive, and historical usage, territorial coverage, and interpretations may vary.
