On 10 January 1820, the Department of Cundinamarca, one of the three official departments of the republic, adopted arms of its own alleging that the arms of the republic were only used in Venezuela. On 12 July 1821, the national congress decreed that the arms of Cundinamarca must be used on the common flag as part of the national coat of arms until new arms could be decreed. Thus, the departmental flag of Cundinamarca was converted into the national flag of Gran Colombia and was officially used in the department of Venezuela.
