Her inheritance and the property given to her by Hammuda Pasha made up the most important habous in the country; in totally it is believed to have amounted to almost 90,000 hectares scattered through the whole country. The revenue of these lands financed several funds supporting the needy at the Aziza Othmana hospital as well as the maintenance of religious buildings in Tunis and in the holy cities of Mecca, Medina, and Jerusalem. Only a portion was retained for her descendants. It was not until 1957 that the habous was dissolved and Aziza Othmana's property was liquidated or nationalised. Hammuda's other spouses reflect mostly the need for political alliances:   In 1663, tired by age, he progressively divested himself of power in favour of his three sons: Murad II Bey received the succession to the Beylik of Tunis, Mohamed el-Hafsi Bey gained the sanjaks of Kairouan, Sfax, Sousse, Monastir and the whole southern part of the country, and the youngest brother Hussein Bey gained the sanjaks on the border with Algeria. Hammuda died in 1666 at Dar El Bey, which he had built so that he could reside closer to his people. On his death he was buried in the mausoleum located under his mosque, in the corner opposite the minaret. Anglo-Dutch Gold Coast Treaty (1867)  The Anglo-Dutch Gold Coast Treaty of 1867 redistributed forts along the Dutch and British Gold Coasts in order to concentrate the parties' areas of influence. All forts to the east of Fort Elmina were adopted by Britain, and all forts to the west by the Netherlands. Whereas the Dutch forts on the Gold Coast were a colonial backwater in the 19th century, the British forts were slowly developed into a full colony, especially after Britain took over the Danish Gold Coast in 1850. The presence of Dutch forts in an area that became increasingly influenced by the United Kingdom was deemed undesirable, and in the late 1850s British began pressing for either a buyout of the Dutch forts, or a trade of forts so as to produce more coherent areas of influence. In the Dutch political landscape of the time, a buyout was not a possibility, so a trade of forts was negotiated. In 1867, the "Convention between Great Britain and the Netherlands for an Interchange of Territory on the Gold Coast of Africa" was signed, in which all Dutch forts to the east of Elmina were handed over to Britain, while the British forts west of Elmina were handed over to the Netherlands.
