In Ancient times, what we call France now was called Gaul or Transalpine Gaul as a way to distinguish it from northern Italy Cisalpine Gaul. Gaul was the name was given to the land by the Romans. Following the collapse of the Roman Empire, various tribes took over notably the Franks who where a Germanic tribe who with King Clovis conquered the areas in modern day France, Belgium and Germany which saw him become king in 494AD. The area was called the Empire of the Franks. The name Francia is used to describe France's side of the empire and it would be used long after Charlemagne's empire was carved up. It is believed that the Franks got their name from the old English word Franca meaning free as the Franks post conquering
Gaul lived tax free. France gets its name from the Franks and was fully declared France (albeit as the Kingdom of France) by King Philip 2nd of France in 1190.
