Anglo-Portuguese alliance signed at Westminster
1373
Edward III's envoys and the Portuguese embassy signed a treaty of perpetual friendship between the two crowns. It promised mutual aid against any enemy and was reaffirmed several times across the centuries, most notably during the Napoleonic Wars and the World Wars. It remains, technically, the oldest active diplomatic alliance in the world today.
