A passport is a document, issued by a national government, which certifies, for the purpose of international travel, the identity and nationality of its holder. The elements of identity are name, date of birth, sex, and place of birth.
Most often, nationality and citizenship are congruent. A passport does not of itself entitle the passport holder to consular protection while abroad or any other privileges, in the absence of any special agreements which cover the situation. It does, however, normally entitle the passport holder to return to the country which issued the passport.
Rights to consular protection arise from international agreements, and the right to return arises from the laws of the issuing country. A passport does not represent the right or the place of residence of the passport holder in the country which issued the passport.
One of the earliest known reference to what appears to be a passport is found in the Hebrew Bible. In Nehemiah 2:7 to 9, attributed to the time of the Persian Empire in about 450 BC, it is said that Nehemiah, an official serving King Artaxerxes I of Persia, asked leave to travel to Judea, and the king granted leave and gave him a letter "to the governors beyond the river" requesting safe passage for him as he traveled through their lands.
It is considered unlikely that the term passport is derived from sea ports, but is considered likely to derive from a medieval document required to pass through the gate (porte) of a city wall. In medieval Europe, such documents were issued to travelers by local authorities, and generally contained a list of towns and cities into which a document holder was permitted to pass. On the whole, documents were not required for travel to sea ports, which were considered open trading points, but documents were required to travel inland from sea ports.
Early passports included a description of the passport holder. Attachment of photographs to passports began in the early decades of the twentieth century, when photography became widespread.In the later part of the nineteenth century and up to World War I, passports were not required, on the whole, for international travel in Europe, and crossing a border was easy. Consequently, comparatively few people had passports. The breakdown of the European passport system of the early part of the nineteenth century was a result of rail travel.
Trains, used extensively from the mid-nineteenth century onward, traveled rapidly, carried numerous passengers, and crossed many borders. Those factors made enforcement of passport laws difficult. The general reaction was abolition of passport requirements.The Ottoman Empire and the Russian Empire maintained passport requirements for international travel, in addition to an internal-passport system to control travel within it.
An international conference on passports and through tickets, held by the League of Nations in 1920, recommended that passports be issued in French, historically the language of diplomacy, and one other language. Nowadays, the ICAO recommends that passports be issued in English and French, or in the national language of the issuing country and in either English or French. On July 14th, 2008, the United States Department of State began to issue passport cards, a credit card sizd ID document valid for land or sea travel to Canada, Mexico, the Caribbean and Bermuda.
The passport card has the same requirements and adjudication standards for issuance as a regular passport, however it costs only dollar 20 for those who already have a passport. The cost is dollar 45 for those applying for the first time. The purpose of the passport card is to provide a secure document for those citizens who frequently cross the border and need a more convenient document to comply with the Western Hemisphere Travel Initiative requirements.
