Al Sabah became Kuwait's monarchy in 1938.[77] One tradition has it that political power went to the Sabahs as part of an explicit agreement in 1890; merchant families focused on the trade while the House of Sabah and other notable Kuwaiti families provided protection of city housed within Kuwait's wall. The man chosen was a Sabah, Sabah I bin Jaber. Sabah diplomacy may have also been important with neighbouring tribes, especially as Bani Khalid power declined. This selection is usually dated to 1756.[78]
In 1762, Sabah I died and was succeeded by his youngest son, Abdullah. Shortly after Sabah's death, in 1766, the al-Khalifa and, soon after, the al-Jalahima, left Kuwait en masse for Zubara in Qatar. Domestically, the al-Khalifa and al-Jalahima had been among the top contenders for power. Their emigration left the Sabahs in undisputed control, and by the end of Abdullah I's long rule (1762–1812), Sabah rule was secure, and the political hierarchy in Kuwait was well established, the merchants deferring to direct orders from the Shaikh. By the 19th century, not only was the ruling Sabah much stronger than a desert Shaikh but also capable of naming his son successor. This influence was not just internal but enabled the al-Sabah to conduct foreign diplomacy. They soon established good relations with the British East India Company in 1775.[78]
