The original design of the Andorran flag, which didn't have the arms, is from 1866, but the current design with the present arms was introduced around 1949 and standardized in 1993, before then, a different design of the arms was used, and there was also briefly a horizontally striped flag with a crown.
Then comes the Romanian, from 1834, and the Andorran, from 1866. Chad, Armenia and Moldova all come from the second half of the twentieth century.
