Ludvig (Lodewyck) Fabritius (14 September 1648, Brazil – 6 October 1729, Stockholm) was the Swedish ambassador to Safavid Iran during the reign of King Charles XI (r.
1660–1697) and Charles XII (r.
1697–1718).
After an early career in the Russian army, he became a diplomat representing the Swedish crown.
Fabritius led three missions to the Safavid court: in 1679-80, 1683–84, and 1697-1700.
His efforts were characterized by the desire to establish a new transit route between Sweden and Iran through Russia (with Narva as its hub), and several attempts to establish a fruitful alliance against the common enemy: the Ottoman Empire.
Fabritius presented an invitation to the Safavid king from the Swedish king to join the Holy League, and was involved in the establishment of several Safavid-Swedish economic and trade agreements.
