Siyu's main claim to historical fame is that it through several battles withstood the Sultans of Zanzibar. In 1843 the Sheikh of Siyu, Bwana Machaka wa Shee, and the new Sheikh of Pate, repudiated the sovereignty of Seyyid Said, Sultan of Oman and Zanzibar. In response, Seyyid Said assembled an army consisting of 2000 people from Muscat, Baluchistan and Lamu. Leading them was his cousin, General Seyyid Hemed bin Ahmed Al-Busaidy, known as "Amir Hemed". He had previously been Governor of Bandar Abbas (in 1824). He landed at Faza in early January 1844. On 6 January they moved towards Siyu, but were ambushed and forced back to Faza. After three weeks without a victory Amir Hemed sailed off.
