Answer:
Its early independence and the wealth gained from oil led to good relations with the West.
Explanation:
The modern Saudi state was founded after the unification of Saudi Arabia by the last king Abdelaziz bin Saud (or Bin Saud). In 1902 Riyadh, the ancestral capital of the Al-Saud dynasty, was conquered by the rival family Al Rashid. Continuing his conquests, Abdelaziz subjugated Al-Hasa, Al-Qatif, the rest of the Nechd and Hijaz between 1913 and 1926. On January 8, 1926, Abdelaziz bin Saud became the king of Hijaz. On January 29, 1927 he took the title of King of Nejd (the previous title of Nejd was that of the Sultanate of the Nejd). Through the Treaty of Jida, signed on May 20, 1927, the United Kingdom recognized the independence of the kingdom of Abdelaziz (then known as the kingdom of the Nejd and the Hijaz). In 1932, these regions were unified in the current Kingdom of Saudi Arabia.
The discovery of oil in March 1938 economically transformed the country exceptionally, and since then has given the kingdom great legitimacy over the years. King Faisal was assassinated by his nephew on March 25, 1975 and succeeded by Khalid. Today, Saudi Arabia maintains an intense economic relationship with many Western nations thanks to its oil resources. Saudi Arabia became a member of the United Nations Organization in 1945 and is a founding member of the Arab League, the Cooperation Council for the Arab States of the Gulf, the Islamic World League, OPEC and the Organization of the Islamic Conference (current Organization for Islamic Cooperation.) Plays a prominent role in the International Monetary Fund and the World Bank, and in 2005 joined the World Trade Organization.
