The Omani events also misspell the Imam as Iman.
On the topic of Oman during this time period, it has a fairly interesting history of competing powers between elected Imams, and dynastic Sultans, some of whom held both titles simultaneously. This power struggle began over a thousand years ago, and continued up until the 1950's with the unification of Muscat and Oman. This dynamic situation being represented by a single lackluster event is fairly underwhelming.
The driving of the Portuguese out of Oman, and even out of parts of East Africa, and the control of East African trade are really interesting as it's one of the few cases in which a colonial power was not only expelled by the local population, but was also pursued out of their other foreign holdings resulting in their maritime supremacy in the Indian Ocean being supplanted. Unfortunately, there are no links between the Zanzibar and Hormuz trade nodes, making this Omani trade empire fairly unworthwhile.
