Tan Sri Haji Dato' Anwar bin Abdul Malik was a Malaysian politician (1898–1998). Anwar along with, Dato' Onn Jaafar, Tan Sri Mohamad Noah Omar, Haji Syed Alwi bin Syed Sheikh al-Hadi and Syed Abdul Kadir Mohamad formed the United Malays National Organisation to counter the Malayan Union that was undermining the Malay Sultans's powers and threatened the Malays of their rights as Bumiputera.
Anwar was credited with giving the United Malays Organisation (UMO) its name. Zainal Abidin Ahmad later on added the word "National" into the name and thus becoming the United Malays National Organisation. After the Second World War, the Malayan Union was formed by the British and it was strongly opposed by the Malays as the union threatened Malay sovereignty over Malaya.
Anwar, along with Haji Syed Alwi bin Syed Sheikh al-Hadi and Syed Abdul Kadir Mohamad, went to Batu Pahat to meet the district officer, Dato' Onn Jaafar, who was a close friend of Anwar's. Together, they created the idea of forming a single party that would be strong enough to oppose the Malayan Union. They were later on joined by Mohamad Noah Omar who became the first Speaker of the Dewan Rakyat. After the meeting, Anwar became the representative to Johor Bahru to rally the Malays together to join the proposed idea of forming one party. Onn Jaafar at that time, together with the Malays from Batu Pahat, had formed, the Johor Peninsular Malay Movement. (Pergerakkan Melayu Semenanjung Johor). The movement had drawn many from Johorean towns such as Muar, Tangkak, Pontian and Kluang. Onn Jaafar then asked his fellow companions on what name should they give the party. Anwar suggested "United Malays Organisation" (UMO). Everyone agreed. On that night, Onn wrote a letter to Utusan Melayu that published the letter, announcing the formation of UMO and proposed congress with other Malay parties to join UMO. A series of Malay congresses were held, culminating in the formation of the nationalist party, United Malays National Organisation (UMNO) on 11 May 1946 at the Third Malay Congress in Johor Bahru, with Datuk Onn Jaafar as its leader.
