Zanzibar is an insular semi-autonomous region which united with Tanganyika in 1964 to form the United Republic of Tanzania. It is an archipelago in the Indian Ocean, 25–50 km (16–31 mi) off the coast of the African mainland, and consists of many small islands and two large ones: Unguja and Pemba Island. The capital is Zanzibar City, located on the island of Unguja. Its historic centre, Stone Town, is a World Heritage Site.

The Anglo-Zanzibar War was a military conflict fought between the United Kingdom and the Sultanate of Zanzibar on 27 August 1896. The conflict lasted between 38 and 45 minutes, marking it as the shortest recorded war in history. The immediate cause of the war was the suspicious death of the pro-British Sultan Hamad bin Thuwaini on 25 August 1896 and the subsequent succession of Sultan Khalid bin Barghash. The British authorities preferred Hamoud bin Mohammed, who was more favourable to British interests, as sultan. The agreement of 14 June 1890, instituting a British protectorate over Zanzibar, specified that a candidate for accession to the sultanate should obtain the permission of the British consul; Khalid had not fulfilled this requirement. The British considered this a casus belli and sent an ultimatum to Khalid demanding that he order his forces to stand down and leave the palace. In response, Khalid called up his palace guard and barricaded himself inside the palace.

People have lived in Zanzibar for 20,000 years. History properly starts when the islands became a base for traders voyaging between the African Great Lakes, the Somali Peninsula, the Arabian peninsula, Iran, and the Indian subcontinent. Unguja offered a protected and defensible harbour, so although the archipelago had few products of value, Omanis and Yemenis settled in what became Zanzibar City as a convenient point from which to trade with towns on the Swahili Coast. They established garrisons on the islands and built the first mosques in the African Great Lakes Region.

As a ship's boat, the pinnace is a light boat, propelled by oars or sails, carried aboard merchant and war vessels in the Age of Sail to serve as a tender. The pinnace was usually rowed but could be rigged with a sail for use in favorable winds. A pinnace would ferry passengers and mail, communicate between vessels, scout to sound anchorages, convey water and provisions, or carry armed sailors for boarding expeditions. The Spanish favored them as lightweight smuggling vessels while the Dutch used them as raiders. In modern parlance, "pinnace" has come to mean an auxiliary vessel that does not fit under the "launch" or "lifeboat" definitions.
