In 1823, Turki re-emerged to form an alliance with Sawaid, the ruler of
Jalajil in
Sudair, and had soon established himself in
Irqah. He made further incursions into Najd, in which he seized major settlements such as Durma and Manfuhah in order to isolate Riyadh and its Egyptian garrison. By August 1824, Riyadh itself came under siege and fell a few months later; Turki designated Riyadh as the new Saudi capital the same year With Hejaz and the Red Sea remaining in Egyptian hands, further expansion was directed eastwards. The conquest of the
Eastern Province was achieved in 1830, in response to a Bedouin invasion from this region led by the
Banu Khalid. Efforts to extend Saudi influence along the
Persian Gulf littoral, however, met with mixed success. The mere threat of invasion was enough to subdue Oman in 1833 yet Bahrain revolted in the same year (having agreed to pay tribute three years prior), a situation that remained unresolved at the time of Turki’s death.{{cite thesis|author=Bilal Ahmad Kutty|title=Political and religious origins of Saudi Arabia|url=https://core.ac.uk/download/pdf/144515638.pdf|location=
