a force under his younger brother Ismail Samani to capture Bukhara, which welcomed him. Nevertheless, the Bukhar-Khudah continued to officially remain in control of the city. In 885, a disagreement over where tax money should be distributed caused a falling out between Nasr and Isma'il. A three year struggle ensued, in which Isma'il proved victorious. Although he took effective control of the state, he did not formally overthrow his brother, instead remaining in Bukhara. He did so because Nasr had been the one whom the Caliph had given the formal investiture of Transoxiana to; in the caliph's eyes, Nasr was the only legitimimate ruler of the region. Isma'il therefore continued to formally recognize Nasr as ruler until the latter's death in August of 892, at which point he officially took power.
