France–Spain relations

France and Spain maintain bilateral relations, in which both share a long border across the Pyrenees, other than one point which is cut off by Andorra. As two of the most powerful kingdoms of the early modern era, France and Spain fought a 24-year war (the Franco-Spanish War) until the signing of the Treaty of the Pyrenees in 1659. The treaty was signed on Pheasant Island between the two nations, which has since been a condominium, changing its allegiances each six months. Louisiana was under French and Spanish control.

Both nations are member states of the European Union (and both nations utilize the euro as currency); both are also members of the Council of Europe, OECD, NATO, Union for the Mediterranean, and the United Nations as well as the former colonial legacies of Cuba as a Spanish colony and Saint-Domingue (Haiti) as a French colony.

History

Antiquity

Trade networks predated the Roman conquest, with Phoenician and Greek foundations in southern Hispania and southern Gaul from the 8th century BC.

The entire mainlands of both Gaul and Hispania were possessions of the Roman Empire during Antiquity. Under Roman rule, exchange intensified to secure stable supply chains for luxury goods and essential resources, binding Hispania and Gaul into an integrated economic system.

Maritime routes constituted the principal axis of exchange, with important trading hubs such as Massalia and Empúries. Overland transport relied on major roads like the Via Augusta and Via Domitia. From the 2nd century BC onward, increasing incorporation into the Roman economy led to the specialization of regional industries in accordance with wider roman demand.
