Timeline

1301–1304Khorasan · KhorasanFrom 1301 to 1304, Öljaitü was appointed by his brother Ghazan to govern Khorasan, ruling the eastern provinces and maintaining military pressure on the northern tribes. Though not yet enthroned, he built up military and political prestige in the east, laying the groundwork for his rapid accession after Ghazan's death in 1304.
1304Tabriz · East AzerbaijanAfter Ghazan's death in 1304, Öljaitü returned from Khorasan and was acclaimed by the princes as the eighth Ilkhan. He initially continued Ghazan's Islamization policies, retained Rashid al-Din as chief minister, and began adjusting the balance of power between the center and the various tümen.
1305–1310Sultaniyya · ZanjanAfter 1305 Öljaitü vigorously developed Sultaniyya as his new capital, launching large-scale building projects there. Around 1310 he openly converted to Twelver Shia Islam, making the Ilkhanate a rare Shia Mongol regime in the Islamic world and provoking tensions with Sunni neighboring states.
