It is believed that they came from a place in the north called Shungwaya, which has yet to be found. The Shirazi apparently came from the north as well. Traditionally, they claim that they came from the aristocratic families and dynasties that composed the Ozi kingdoms of Shaka, Mwana, Ungwana, Malindi, and Mombasa. Most historians place no real weight on this story, however, and the Shirazi have mixed with the Swahili until little remains to distinguish them. The Swahili, as well as the Bajun and Shirazi, rely mainly on fishing and agriculture.
Agriculture is also important, with fires used to clear the land before planting.
This method is described in 2nd century writings, demonstrating the amount of tradition behind the Swahili people. The coconut plays a primary role in the local economy, being used for building, making baskets and ropes, food, drink and oil. Root crops are also important to the area, as are rice, maize and fruits. Wood working and weaving a variety of fibers into baskets, mats, etc., are important crafts to the area. The beautiful carved doors in Lamu are a good example of the carving skill of the Swahili people.
