Zanzibar is a semi-autonomous region. It joined with Tanganyika in 1964 to form the United Republic of Tanzania. The capital is Zanzibar City, which is located on Unguja. Its historic center is known as Stone Town. Stone Town is recognized as a World Heritage Site.

The islands are famous for their diverse industries. They are often called the "Spice Islands."

This name comes from the production of various spices. Key crops include cloves, nutmeg, cinnamon, coconut, and black pepper. The islands also produce raffia. The marine ecosystem is also vital for the economy. It supports fishing and algacultural industries. Alga culture, or seaweed farming, is a significant activity.

Human history in Zanzibar began at least 20,000 years ago. This is evidenced by the presence of microliths from the Later Stone Age.

By the 6th century, settled agricultural and fishing communities existed. Archaeological finds at Fukuchani show people used timber for buildings. Over time, architectural styles evolved significantly. By 1150, houses were built with mud and coral walls. By the 13th century, wealthy residents used stone bonded with mud. In the 14th century, lime was used to bond stone. This allowed for the construction of flat roofs. These stone houses were an indigenous development of local architecture.

Zanzibar became a central Swahili trading town by the 10th century. Swahili merchants acted as brokers for long-distance trade. They connected the African hinterland with the Indian Ocean world. Traders brought goods like gold, ivory, and ambergris to the coast. In return, they sought items like Indian cloth. This interaction helped evolve the Swahili culture. This culture developed an Arabic-script literary tradition. The Swahili language is a Bantu language. However, it includes loanwords from Arabic due to historical contact.

European influence began with the arrival of the Portuguese in 1498. Captain Vasco da Gama visited the region during this time. Zanzibar became part of the Portuguese Empire around 1503 or 1504. For nearly two centuries, the Portuguese maintained a presence. However, they did not closely administer the islands. They often used the area as a trade depot. This changed after the Sultan of Mombasa killed Portuguese residents in 1631. The Portuguese then appointed European governors. Later, the Swahili elites invited Omani aristocrats to help remove the Europeans. In 1698, Zanzibar came under the influence of the Sultanate of Oman.

In the 19th century, the islands saw significant political and social changes. Said bin Sultan moved his capital from Muscat, Oman, to Stone Town. This happened between 1832 and 1840. The sultanate controlled much of the Swahili coast, known as Zanj. During the reign of Majid bin Said, Zanzibar became a major center for the Indian Ocean slave trade.

In the mid-19th century, as many as 50,000 slaves passed through the port of Malindi annually. This was a period of great hardship for many. Simultaneously, traders from the Indian subcontinent settled on the islands. They were encouraged by Said bin Sultan to participate in commerce.

Today, tourism is a major driver of the economy. This industry has grown rapidly due to government promotion. In 1985, there were only 19,000 tourists. By 2016, that number rose to 376,000. By 2025, the number reached 917,000.
