The story
Kilwa Kisiwani grew into one of the richest towns on the Swahili Coast of East Africa between about 1000 and 1500 CE. Swahili culture mixed African traditions with ideas from Arabia, Persia and India, all connected by the Indian Ocean.
Kilwa's rulers controlled the trade in gold that came from Great Zimbabwe and the inland, along with ivory. Ships sailed with the monsoon winds to Arabia, India and even China. Kilwa minted its own copper coins, and one of them was found as far away as northern Australia.
In 1331, the traveler Ibn Battuta visited and praised the city's beauty. Kilwa's builders used coral stone to make the Great Mosque and a huge palace called Husuni Kubwa, with more than 100 rooms and an eight-sided pool.
How it ended
In 1505, Portuguese ships attacked Kilwa and took over the gold trade. Trade routes shifted, and the town slowly lost its wealth and people. Its stone buildings were left to crumble beside the sea.
What life was like
Kilwa's merchants traded gold, ivory and iron for cloth, beads and Chinese porcelain. Many people farmed, fished and built ships. Swahili, the language of the coast, grew from Bantu languages and borrowed words from Arabic. Wealthy families lived in coral stone houses, while others lived in homes of wood and thatch.

Read the full background
Kilwa Kisiwani ('Kilwa Island') is an island, national historic site, and hamlet community located in the township of Kilwa Masoko, the district seat of Kilwa District in the Tanzanian region of Lindi in southern Tanzania. Kilwa Kisiwani is the largest of the nine hamlets in the town of Kilwa Masoko and is also the least populated hamlet in the township with around 1,150 residents.
Historically, it was the center of the Kilwa Sultanate, a medieval Swahili sultanate whose authority at its height in the 13th, 14th and 15th centuries stretched the entire length of the Swahili Coast. At its peak in the Middle Ages, Kilwa had over 10,000 inhabitants. Since 1981, the entire island of Kilwa Kisiwani has been designated by UNESCO as a World Heritage Site along with the nearby ruins of Songo Mnara. Apart from its significant historical reputation, Kilwa Kisiwani is still home to a small and resilient community of natives who have inhabited the island for centuries. Kilwa Kisiwani is one of the seven World Heritage Sites in Tanzania. Additionally, the site is a registered National Historic Site of Tanzania.
