Why did say yid said transfer his capital from muscat to Zanzibar?

Sayyid Said transferred his capital from Muscat to Zanzibar in the early 19th century primarily to take advantage of the island's strategic location for trade. Zanzibar offered better access to the lucrative markets of East Africa and the Indian ocean, especially for the spice trade and the growing slave trade. Additionally, the shift allowed him to strengthen his influence over the regional trade routes and expand his empire's economic base. The move also provided a more favorable climate and resources for agriculture and commerce.
