Mediterranean Passport

The Mediterranean Passport, commonly called a ship’s passport, was created after the United States concluded a treaty with Algiers in 1795. During the early years of independence, America was one of several nations paying tribute to the Barbary states in exchange for the ability to sail and conduct business in the Mediterranean area without interference. This treaty provided American-owned vessels with a “Passport” that would be recognized by Algeria and later by other Barbary states through similar treaties. These Passports were to be issued only to vessels that were completely owned by citizens of the United States, and were intended to serve as additional evidence of official nationality.

In June 1796, a Federal law was passed which required the Secretary of State to prepare a form for the Passort and submit it to the President for approval. The result was a document modeled after a similar British form, called a Mediterranean Pss, which England had employed for the same purpose. The American version was a printed document, on vellum, that measured approximately 15″ X 11.” Centered in the upper half were two engravings, one below the other, (some early examples had a single large engraving of a lighthouse with a ship at anchor across the entire top quarter of the document). Signatures of the President of the United States, Secretary of State, and Customs Collector appear in the lower right-hand corner. The United States seal is in the lower left-hand corner.

The most obvious similarity with the British passport was the presence of a scalloped line of indenture across the upper part of the document which was used as a method of authentication. After they were printed, the Passports were cut along the waved line and the top portion sent to the U.S. Consuls along the Barbary coast. The Consuls subsequently provided copies to the corsairs, whose commanders were instructed to let all vessels proceed, who had passes that fit the scalloped tops.

Every American vessel sailing in this area was to have a Mediterranean Passport as part of its papers. The penalty for sailing without one was $200.00. The master requested the document from the collector and paid a fee of ten dollars. A bond was also required to insure that the Passport was used in accordance with the conditions under which it was obtained, and was canceled when the document was forfeited. New Passports were not required for each succeeding foreign voyage, but it could not be transferred to another vessel, and it was to b returned to the port of original issue if the ship was wrecked or sold.

Mediterranean Passports were received by the various customs districts pre-signed by the President and Secretary of State. The Collector could then insert the vessel’s name and tonnage, master’s name, number of crew members, and the number of guns mounted on the vessel, into the appropriate clanks and sign the document. It is interesting to note that I have found one Passport issued and dated nearly six months after the President whose signature appears on the document had left office. One might wonder just how efficiently these rather important forms were managed. Unused and outdated Passports were supposed to be returned to the Treasury Department, after first being canceled by cutting holes through the seals.

Sea Letter

Unlike the Mediterranean Passport, the Sea Letter does not appear to have had any formal establishment, but rather acquired validity through years of maritime use. The term “Sea Letter” has been used to describe any document issued by a government or monarch to one of its merchant fleet, which established proof of nationality and guaranteed protection for the vessel and her owners. However, it the Sea Letter use by the United States after 1789 that is of particular interest here.

The 1822 edition of The Merchants and Shipmaster’s Assistant described the Sea Letter as a document which “specifies the nature of the cargo and the place of destination,” and says that is was only required for vessels bound to the Southern Hemisphere. It further “indicated that “…this paper is not so necessary as the passport, because that, in most particulars, supplies its place.” In 1859 the document was defined as part of the ship’s papers when bound on a foreign voyage,”…it is written in four languages, the French, Spanish, English, and Dutch, and is only necessary for vessels bound round Cape Horn and the Cape of Good Hope.”

Like the Mediterranean Passport, the Sea Letter was a remarkably standardized document, which changed little during the time that it was used. Usually printed on heavy grade paper, approximately 16″ x20″ in size, the first Sea Letters carried only three languages instead of four. However, they soon became known as “Four Language Sea Letters.”

The statement within the document conveys in part that the vessel described is owned entirely by American citizens, and requests that all “Prudent Lords, Kings, Republics, Princes, Dukes, Earls, Barons, Lord, Burgomasters, Schepens, Consullors…” etc., treat the vessel and her crew with fairness and respect. The signatures of the President of the United Stated, the Secretary of State, and the customs collector appear, usually in the middle portion of the document, The United States seal is present, while customs and consular stamps or seals are frequently in evidence.

Sea Letters are mentioned in the formative maritime legislation forged by the new Federal governments. Like passports, they provided additional evidence of ownership an nationality, but the criteria by which a shipmaster utilized one document over the other is not completely clear. It was explained at the time that both documents were “rendered necessary of expedient by reason of treaties with foreign powers,” a statement which suggests that certain nations required a particular document because of existing agreements with the United States.

In any case the Sea Letter was valid for only a single voyage, and a bond does not seem to have been required. Neither was it to be returned to the collector when the voyage was completed. Indications are that, as the years progressed, Sea Letters were being used more often by whaling ships than by merchant vessels, perhaps because American whalers fished in areas where this document was preferred as proof of national origin.

By providing a statement of American property, signed by the President of the United States, the Mediterranean Passport and the Sea Letter were intended to confirm our status as a neutral nation, when international conflict put added dangers on America’s commerce at sea. By mid-century, however, much of what had previously threatened our shipping was being neutralized by the expanding power of the United States. In 1831 Congress eliminated the fee required for obtaining a Mediterranean Passport. It was argued a the time that the revenue arising from that source, and the protection which it provided, were no longer objects of any importance. As our merchant fleet became more secure, fewer shipowners and shipmasters considered these documents as necessary to guarantee their rights and safety in foreign lands.*

Both pieces were considered important parts of a ship’s papers in the 1800s. They were kept aboard ship during the voyage and deposited, along with the Registry Certificate, with the appropriate U.S. consular authority anytime the vessel was in a foreign port. The Mediterranean Passport had disappeared from use by 1860, while the Sea Letter was still in evidence several years later.

Today both pieces are considered to be important documents in any maritime collection. However, they are also highly valued by autograph collectors and investors, which keeps many fine pieces in private hands.

*It is important here to note that both documents were intended only to protect the vessel from capture of destruction by providing American, i.e., nonbelligerent, ownership. American crew members aboard these ships were still vulnerable to impressment, especially if they did not carry their own personal protection certificates as proof of citizenship.

The United States modeled the ship’s Passport after a similar British document known as a Mediterranean pass, shown above. This particular document was issued by the Admiralty to the Brigantine LYDIA for a whaling voyage from Boston to the African coast, 31 October 1772. Admiralty seal and revenue stamps are present along the left-handed edge. Like its American counterpart, the Mediterranean Pass was printed on vellum, and is similar in dimensions and style.

A typical Mediterranean Passport issued to the ship CANTON PACKET from the collector at the district of Bristol & Warren, Rhode Island, on 1 November 1832. Signed by President Andrew Jackson, and Edward Livingston, Secretary of State. The number “5” written above the seal indicates that this was the fifth Passport issued there during that year. This figure can provide valuable information as the number of Passports issued at various ports, and how it was effected by perceived threats to American shipping during periods of international conflict.

A $2,000 Bond signed by the master, and the agent or owner of the brigantine ARGUS. Issued at the Providence customs district, it pledged compliance with the conditions under which they hove obtained their vessel’s Passport. The document was issued on 7 December 1807, three days after the applicants had received the passport. (Courtesy of Rhode Island Historical Society.)

This Four-Language Sea Letter was issued to the whaling bark JOSEPH MAXWELL of Fairhaven, Massachusetts, 15 December 1863. Unlike the Mediterranean Passport, the Sea Letter required the signature of a notary official to whom the master had given a sworn oath of accuracy regarding the information on the document. This example bears the signatures of President Abraham Lincoln and Secretary of State William P. Seward at right, and the great seal at the bottom. View in catalog →
