The House of Al Saud is the ruling royal family of Saudi Arabia. It is composed of the descendants of Muhammad bin Saud, founder of the Emirate of Diriyah, known as the First Saudi State (1727–1818), and his brothers, though the ruling faction of the family is primarily led by the descendants of Abdulaziz bin Abdul Rahman, the modern founder of Saudi Arabia. It forms a subtribe of the larger prominent ancient Banu Hanifa tribe of Arabia, from which well known 7th century Arabian theologist Maslama ibn Ḥabīb originates. The most influential position of the royal family is the King of Saudi Arabia, an absolute monarch. The family in total is estimated to comprise 15,000 members; however, the majority of power, influence and wealth is possessed by a group of about 2,000 of them. Some estimates of the royal family's wealth measure their net worth at $1.4 trillion. This figure includes the market capitalization of Saudi Aramco, the state oil and gas company, and its vast assets in fossil fuel reserves, making them the wealthiest family in the world and the wealthiest in recorded history.

The Palace Law of Succession, Buddhist Era 2467 (1924) governs succession to the Throne of the Kingdom of Thailand, under the ruling House of Chakri. Succession matters prior to the end of absolute monarchy in 1932 could be contentious, especially during the Ayutthaya period from the 14th to 18th centuries. In 1924, King Vajiravudh attempted to clarify the succession process by laying down the Palace Law of Succession. It was promulgated and came into effect in November 1924 as, in part, an attempt to eliminate the vagueness relating to succession within the Thai monarchical regime and to systematically resolve previous controversies. In 1932, after Siam became a constitutional monarchy, various amendments relating to succession were introduced. The 1997 Constitution of Thailand relied on the law with regards to succession, but the 2006 Interim Constitution made no mention of succession, leaving it to "constitutional practice". The 2007 Constitution again relied on the Palace Law. The preamble of the 2014 interim constitution of Thailand abrogated the 2007 Constitution, with the exception of chapter 2, concerning the monarchy and the succession.
