Brunei is a small, oil-rich sultanate on the northern coast of Borneo in Southeast Asia, surrounded by Malaysia. Governed by the Sultan of Brunei, it's one of the few absolute monarchies left in the world. The country is known for its wealth, with citizens enjoying free education, healthcare, and no personal income tax. Bandar Seri Begawan, the capital, showcases Islamic architecture in its mosques, notably the Omar Ali Saifuddien Mosque, and the opulent Istana Nurul Iman, the Sultan's palace. Despite its wealth, Brunei maintains a conservative Islamic society with strict laws.
