When Abdul Rahman's brothers — Saud and Abdullah — were struggling for power in 1865, Abdul Rahman and his brother Muhammad tended to align themselves with Saud. In 1871, after Saud had taken the capital Riyadh. Abdul Rahman was sent to Baghdad to negotiate with the Ottoman Empire for help. Unsuccessful after two years, he tried to take Al-Hasa in the east where Abdullah was now based, but without success, and eventually returned to Riyadh. After Saud's death in 1875, Abdul Rahman was recognized as successor, but within a year Riyadh was taken by Abdullah. He was forced to abdicate. In 1887 the sons of Saud bin Faisal, who kept up desultory hostilities against their uncles, managed to capture Abdullah. The Rashidi amirs of Ha'il were able to secure Abdullah's release in exchange for Abdul-Rahman. Abdullah was taken to Ha'il and a Rashidi emir appointed to him to govern Riyadh. Abdul Rahman was able to rise in revolt in 1887 and take and defend Riyadh, but his attempts to expand control ended in disaster. When Abdul Rahman became the undisputed leader of the House of Saud in 1889, he attacked and regained Riyadh. However, the Saudi forces were defeated in the Battle of Mulayda, and Abdul Rahman and his family were forced to flee.
