Abdulaziz Al Saud vs Mary II of England

Abdulaziz Al Saud led a small force to recapture Riyadh from the rival Al Rashid tribe. This victory marked the beginning of his campaign to unify the Arabian Peninsula under Saudi rule.

Abdulaziz Al Saud proclaimed himself King of Hejaz and Nejd after conquering the Hejaz region. This consolidated his control over most of the Arabian Peninsula, laying the foundation for modern Saudi Arabia.

Abdulaziz Al Saud unified the regions of Hejaz, Nejd, and other territories into the Kingdom of Saudi Arabia. He became its first king, establishing the Al Saud dynasty's rule.

Abdulaziz Al Saud signed a concession agreement with Standard Oil of California, leading to the discovery of oil in 1938. This transformed Saudi Arabia's economy and global influence.

Mary II accepted the invitation from English parliamentarians to replace her father James II. She and her husband William of Orange invaded England with a Dutch fleet, forcing James II to flee. This bloodless transfer of power established parliamentary sovereignty over the monarchy.

Mary II was crowned joint sovereign with her husband William III at Westminster Abbey. She accepted the Bill of Rights, which limited royal powers and affirmed parliamentary authority. This coronation formalized the new constitutional arrangement.

Mary II served as regent while William III campaigned in Ireland against James II's forces. She effectively governed England, managing the Treasury and military logistics. Her regency demonstrated her administrative competence and maintained stability.

Mary II died of smallpox at Kensington Palace at age 32. Her death deeply affected William III and the nation. She was buried in Westminster Abbey. Her early death ended her joint reign and left William as sole monarch.
