Ki Bagoes Hadikoesoemo or Ki Bagus Hadikusumo was born in Kauman's hometown, Yogyakarta on 11 Rabi'ul Akhir 1308 H / 24 November 1890. He is the third son of five children of Raden Kaji Lurah Hasyim, a white court servant or Islamic religious official at the Yogyakarta Palace. In 1937, Ki Bagus was invited by Mas Mansoer to become Deputy Chairman of PP Muhammadiyah. In 1942, when KH Mas Mansur was forced by Japan to become chairman of the Putera (People's Power Center), Ki Bagus replaced the general chairman of Muhammadiyah he had left. This position was held until 1953. During his time as the leader of Muhammadiyah, he was a member of BPUPKI and PPKI

The government has bestowed the title of national hero on Ki Bagus Hadikusumo. The inauguration of the title of national hero, through Presidential Decree No. 116/TK 2015 dated November 4, 2015 by President Joko Widodo. This is not without reason. Ki Bagus Hadikusumo's grandson, Muhammad Nuskhi explained that in preparation for Indonesian independence, Ki Bagus Hadikusumo was a member of the Investigating Agency for Preparatory Work for Indonesian Independence (BPUPKI). In addition, at the beginning of the independence of the Republic of Indonesia he was a member of the PPKI (Committee for the Preparation of Indonesian Independence). One of the great roles of Ki Bagus, was to lay the foundation for the Preamble or the Preamble to the 1945 Constitution which was later contained in Pancasila. ''He then suggested that the seven words in the Jakarta Charter be omitted, so that they sound like those contained in the first precepts of Pancasila,'' said Muhammad Nuskhi.

In the beginning, Bung Karno put forward the basic concept of the state. In this concept he proposes "Divinity" at the end as the basis of the state. However, in this case, Ki Bagus objected and rejected the concept. He suggested that the word "Ketuhanan" be replaced with "Belief in the One Supreme God" and placed in the first part as the basis of the state. This was done because of his character who always put forward an attitude of tolerance in religion. As a result, the opinion was accepted and this is the success of Muhammadiyah's diplomacy. In other words, it can be understood that Muhammadiyah took part in establishing the Unitary State of the Republic of Indonesia which is the great home of the Indonesian nation which according to Muhammadiyah's language is Darul 'Ahdi wasy Shahadah.
