The Methuen Treaty was a military and commercial treaty between England and Portugal that was signed in 1703 as part of the War of the Spanish Succession. The treaty stipulated that no tax higher than the tax charged for an equal amount of French wines could be charged for Portuguese wines (but see below) exported to England, and that no English textiles exported to Portugal would be charged any taxes, regardless of the geopolitical situation in each of the two nations (to ensure England would still accept Portuguese wine in periods when not at war with France).
