Invented in the 19th century, the electric telegraph made it possible for people to communicate over long distances. The Ottoman Empire closely followed this new communication technology. The central administration started to lay the first telegraph lines in Rumelia during the Crimean War. Subsequently, telegraph lines were extended into Anatolia. After the completion of the main lines here, in the same century, the political administration carried out efforts to lay telegraph lines in the Arab provinces. The construction of telegraph lines facilitated the communication of the decisions taken by the political administration in the capital Istanbul to the whole country in a short time. Thus, the communication gaps between the centre and the provinces were prevented by the rapid flow of news and information received from distant places and the control of these places by the state authorities was ensured. The geographical location of Jerusalem during the Ottoman period, its importance for the three major religions, and the volume of trade made it necessary for the central administration to lay a telegraph line to speed up the flow of information and news from here to Istanbul. In 1863, it was decided to include the Palestine region in the telegraph network project. In 1864, a land telegraph line was extended from Beirut to El-Arish on the Egyptian border. In the same year, Gaza, Jaffa, Jerusalem, Nablus and Acre were introduced to the telegraph thanks to the cash aid collected from the people and the facilities provided by the state, and thus communication with Istanbul and Europe was ensured. With the erection of poles and the extension of wires, the entire Palestinian region was connected by telegraph lines and telegraph centres were opened in many settlements. During the reign of Abdul Hamid II, the telegraph line was extended from Jerusalem to Aqaba and then to Mecca-Medina, and the communication infrastructure of the holy lands with Istanbul and Europe was completed. The geographical location of the Palestinian region and its holy sites attracted the attention of Western countries. In order to ensure the flow of information from the region, Britain connected the Indian telegraph network it owned to the Ottoman telegraph network via the Gaza-El-Arish line and ensured its contact with strategic positions. France, which was dependent on Britain for telegraph correspondence, worked to establish its own lines. For this purpose, by making an agreement with the Ottoman State, it wanted to lay an underwater telegraph line to Djibouti and Madagascar on the African continent, following the Gulf of Aqaba with the line to be laid through the Palestine region. The focus of the study is the establishment of central and connecting telegraph lines in Jerusalem during the Ottoman period, and the contribution of the lines to the region. It is aimed to contribute to the military, political, and economic life of the Palestine region with the information to be obtained. In this direction, Ottoman archival documents located in the Presidency State Archives Directorate and the press of the period will be examined. In addition, secondary sources written on the subject will be consulted.
