The traditional ancient Roman flags were basically military standards for the respective military legions and were not national flags. The first flag of ancient Roman Republic was the vexillum (plural vexilla), the standard of the Roman cavalry.
The word is derived from the Latin word ‘velum’ which means sail, which is indicative of flag-like standards. The banner cloth was square-shaped hung on a horizontal rod which was fastened to a pole. The horizontal rod had tassels and ribbons with fringes hanging on either side of the banner cloth.

The terminal end of the pole was spear-headed. This spear tip was leaf-shaped. The bearer of the vexillum was known as vexillarius. The color of the traditional flags of the Classical Roman Era was dark red with the letters SPQR emblazoned on it in golden yellow. It was in the Christian era later that the cross was added to the ancient Roman flag.
SPQR is an acronym which initiated from the Latin phrase Senatus Populusque Romanus meaning ‘The Senate of The People of Rome’.
