Which wahhabist leader acquired mecca and medina for his country and ran the government according to the islamic legal and moral code?

Ibn Saud

Explanation:

    Better known as Ibn Saud was the founder and first king of Saudi Arabia. He was descended from a family in the city of Riyadh, in the Nejd region, who led the ultra-Orthodox Vaabite Islamic movement, contrary to all changes to the doctrine of Islam from AD 950.

    During World War I, the British made efforts to gain their sympathy, but at the same time favored their rival Husain Ibn Ali, who ruled the Hejaz region, home to the two main Islamic holy cities, Medina and Mecca.

    Ibn Ali fought against the Turks of the Ottoman Empire, enemies of England, and defeated them, proclaiming himself king of Hejaz. However, losing his English support, he was eventually defeated by Ibn Saud in 1925 who unified the regions and, after consolidating his power over them, changed the name of the kingdom to Saudi Arabia.

    Under his reign, the nomadic tribes of the region were forced to adopt a sedentary regime and abandon their traditional lifestyle, which included revenge, feuds and tribal wars. Similarly, the safety of religious pilgrimages to Mecca and Medina was ensured.
