Omar Ali Saifuddin I ibni Muhammad Alauddin (died 10 July 1795), also known as Al-Marhum Makam Besar, was the 18th Sultan of Brunei and the second son of Sultan Muhammad Alauddin. He was regarded as one of the longest-serving sultans and was renowned for his wise leadership and just rule, merely following his father-in-law, Sultan Hussin Kamaluddin. In fact, he received helpful knowledge, counsel, and experience from his father-in-law when he was still alive during his reigning period.[2]
