The port is historically the oldest operating harbour in the nation and its roots date back to around the 6th century.[6] The Port of Tanga is the second largest port in Tanzania and is a vital part to the city's initial development and economy. The port operates at 90% of its installed capacity and its main cargo iscoal for the cement industry and is a new gateway forcrude oil products.[7] The ports authority has major plans to upgrade the port in increasing its capacity and providing an alternative route for cargo flowing into the country.[8]
Tanga is the starting point of the narrow gaugenorthern railway network that ends inArusha. Construction of this line was started in the 19th century by the Germans. In 2018, the Government of Tanzania invested 5.7 billion Tanzanian Shillings to rehabilitate the line. As of July 2019, diesel powered cargo trains are leaving Tanga Railway Station again and passenger transport between Tanga and Arusha is set to start in September 2019.[9]
The first communities that called Tanga their home were theDigo people and theSwahili states of the 11th to 16th Centuries. However, the earliest documentation about Tanga comes from thePortuguese. During their disruption of the previous trading links Tanga settlement remained a small trading post for the colonists during their occupation of the East African coast for 200 years between 1500 and 1700 when they were ousted.[10] TheSultanate of Oman battled the Portuguese and gained control of the settlement by mid-1700 along withMombasa,Pemba Island andKilwa Kisiwani.[11] The town continued to act as a trading port forivory and slaves under the sultan's rule.[12] Tanga continued to be a prosperous trading hub for slaves with the Arab world until 1873 when the European powers invaded and occupied thus abolishing the slave trade that was no longer serving the colonial powers.[11]

In the 19th Century, growing interests by Europeans for theScramble for Africa brought the Germans to Tanga. The Germans bought the coastal strip of mainland Tanzania from theSultan of Zanzibar in 1891. This takeover designated Tanga into a township and was the first establishment inGerman East Africa.[13] The town became the centre of German colonial administration before the establishment ofDar es Salaam in the early 20th century.
Tanga was chosen in 1889 as a military post of German East Africa, and it became a district office in 1891. The town saw rapid expansion and planned growth under the German occupation. A tram line was built in the city for domestic transport and a port was also built for exports. In 1896 the construction of theUsambara Railway began and was extended toMoshi by 1912. Roads, bridges and the railway enabled industrial growth in the region and many buildings and bridges that are still in operation today in the town are from the German colonial period. The local economy was based mainly on the production ofsisal, which had been brought to the colony several years earlier, and population in the area grew rapidly.[14]
As the coastal town closest toBritish East Africa, Tanga was on the front line of theEast African campaign at the beginning ofWorld War I. On 4 November 1914 a landing by British and Empire forces was repelled in theBattle of Tanga.[15] On 13 June 1916 theRoyal NavybattleshipHMS Vengeance andprotected cruisersChallenger andPioneer bombarded Tanga. On 7 July the protected cruiserHMS Talbot andmonitorSevern enteredManza Bay[16] and put troops ashore who occupied the town.[17] After the War, Britain was given a League of Nations Mandate to prepare Tanganyika for independence and continued to develop Tanga in order to develop its agricultural potential, both to feed the population and so stave of the regular famines in the tetritory and for export. In 1919 Tanga was the country's fourth largest city, but at independence it was the second largest city afterDar es Salaam.
In the early stages of independence, thePort of Tanga continued to be a gateway for the export ofsisal from the region. However, following the adopting of theUjamaa policy, global prices in sisal dwindling, the production that served the city's factories closed and the city lost its main source of income. With the government controlling the agriculture trade and the depreciation in the world prices of sisal the port began to lose revenue.[18]
