In what year was the Arab Caliphate founded?

The first Righteous Arab Caliphate, headed by the Caliph, was founded in 632 after the death of the Prophet Muhammad. Almost the entire Arabian Peninsula was its territory, and the first righteous Caliph Abu Bakr ruled over it. In the process of expansion from the 7th to the 9th century, the borders of the Caliphate stretched to Spain and France in the west and to the borders of modern Pakistan and the Caspian Sea in the east. The Caliphate was a theocratic Islamic monarchy headed by the Caliph, the governor of the Prophet Muhammad. It collapsed in the 10th century due to local separatism, the weakening of the power of the caliphs and external enemies. In 1055, the Seljuks conquered the capital of the last Caliph state, Baghdad.
