The following is an example of one such concession: The Telegraph Concession in Iran in 1862 was a significant agreement that allowed a British company to construct and operate a telegraph line in Persain territory. This concession played a crucial role in the development of telecommunication infrastructure and British influence in Iran during the 19th century.

The concession was granted to a British entrepreneur named Charles Morrison by, Nasir al-Din Shah. The agreement gave Morrison the exclusive rights to build a telegraph line across Persia. This line was intended to connect the Persian Gulf to the Caspian Sea with branches extending to Tehran and other important cities.

The British government supported Morrison in securing the concession as it served British interests in the region. It was not only a means of communication but also had strategic importance as it facilitated the transmission of information and news across the vast Iranian territory and contributed to British control over their interests.

Construction began in 1864 and was completed in several stages over the following years. The concession allowed Morrison's company to operate for 70 years. The telegraph line facilitated communication between Persia and British India, which was also under British control at the time, and it played a role in the coordination of British interests in the region.
