William Harborne of Great Yarmouth, Norfolk (c.1542–1617) was a diplomat, businessman, and English Ambassador to the Ottoman Empire, appointed by Queen Elizabeth I of England.

Establishment of the English Embassy in Constantinople

Following a visit to Constantinople in 1575 by English merchants John Wright and Joseph Clements, Harborne was employed in 1578 by a group of English merchants to travel to Constantinople, via Poland, and obtain permission from the Sultan Murat III for English ships to trade in Ottoman ports. Previously only the French had enjoyed this privilege, which was granted to Harborne in 1580 following negotiations with Sadrazam Sokollu Mehmed Pasha, and correspondence between Queen Elizabeth I and the Sultan. Harborne thus became English Ambassador, in the pay of the Levant Company, an association of traders created for this purpose, led by Edward Osborne and Richard Staper, who had accompanied Harborne on his visits. Harborne received diplomatic credentials from Queen Elizabeth on 20 November 1582. Sailing to Constantinople from London he arrived on 26 March 1583 bearing lavish gifts for the Sultan including an expensive clock. Harborne played a key role in preventing the Ottoman Empire from supporting Catholic Spain in the war with Protestant England that was taking place at the time. Harborne was able to persuade the Porte that Spain was a threat to peace for all of Europe. Although he was unable to obtain a military alliance with the Ottomans, the Spanish-Ottoman protocol was not renewed in 1587. The Elizabethan Treaty was renewed and would survive for 343 years with England and Turkey. The Turkish powers were furious; and the Englishman was threatened several times by French to be turfed out. Harborne also succeeded in obtaining from the Ottomans capitulations and other tariff reductions for English goods, and was charged with obtaining samples and information regarding dyestuffs and fabrics used in the production of cloth and clothing in Turkey at that time. The ambassador departed in August 1588 and was succeeded by Sir Edward Barton, by which time trade had begun to thrive and the post was one of the most powerful positions in the English foreign service. On his return to England Harborne settled at Mundham, Norfolk. He died there on 6 November 1617 and was buried in that parish. There is a monument to his memory in the parish, with a eulogistic inscription in English verse. The Plaque reads: <poem style="margin-left:2em;"> Behold a dead mans howse who full of dayes Retirde here from the world; desert and praise Should sitt uppon his grave in vertuous strife This to instruct and that to wright his life Heires spare your cost; he needs no tombe in death Who Embassied for Queene Elizabeth His next will be when at the generall dome God sends his sovle to fetch his bodye home"
