Treaty of Seeb

[1] The treaty granted autonomy to the imamate in the interior of Oman but recognized the sovereignty of the Sultanate of Muscat.

[2] The Imamate has appeared in cycles for more than 1,200 years in Oman, at times succeeding in expelling the Portuguese colonizers out of southeast Arabia and establishing a thalassocracy that extended its power towards the Persian Gulf and East Africa.

[8] The Imamate of Oman, similar to the Sultanate, was ruled by the Ibadi sect but the former differed politically as it opposed foreign interference in internal affairs and believed that the ruler should be elected.

[3][9] With British assistance by mediator Ronald Wingate, the Treaty of Seeb was signed on September 25, 1920.

The capital of the Imamate was established in the town of Nizwa, one of the traditional centers of power in Oman's history.

[11] The entry and occupation of Fahud on 25 October 1954, an area located within the interior of Oman, by the Muscat Infantry led by Lieutenant Colonel Coriat was considered by the Imamate to be a breach to the Treaty of Seeb, which triggered the Jebel Akhdar War.

[13][14] The brother of the new Imam, Sheikh Talib bin Ali Alhinai, who fled to Saudi Arabia then Egypt, gradually restarted the Jebel Akhdar rebellion and eventually re-joined his followers in Oman.

On all commodities brought from Oman of all kinds to Muscat, Matrah, Sur and all the coast towns nothing more should be taken than 5 percent.
