The Kingdom of Saudi Arabia government worked  - since the respect by Allah (God) to serving the Two Holy Mosques - that provide all resources   to service Al-Rahman guests  (pilgrims ) and facilitate to perform Hajj Rites. Therefore, it vital to increase resources to study new issues related to pilgrimage and services, to identify problems, and provide solutions to them on the basis of scientific methods.

The historical development of the Custodian of the Two Holy Mosques Institute of the Hajj Research (CTHMIHR) can be traced back to 1975. Between 1975 to 1981 the Hajj Research Centre (HRC) existed in the form of a research team within King Abdulaziz University (KAU) in Jeddah. It was established officially at that time as a consultant authority for the High Committee of Hajj and other authorities working in Hajj affairs. The main aim of HRC was to establish an information bank about the Hajj. This information bank functions as a comprehensive scientific reference source that provides several different statistics, details, and facts to assist in the planning of utilities and services during the Pilgrimage. The aims of  HRC as the following:

       1. Establishing an information (data) bank about the Hajj, which is designed to be a comprehensive scientific reference source for

           different statistics, details, and facts to assist in planning utilities and services of the Hajj. 

       2. Building a complete historical record of the documents, photographs, films, maps, and manuscripts about the Hajj, Makkah, and


       3.  Preserving the natural and Islamic environment in the Holy places (Mashaer), Makkah, and Madinah.

In 1983 the HRC was officially transferred from KAU to Umm Al-Qura University (UQU) in Makkah. The Oversight Committee of the HRC was chaired by the Minister of the Interior, with other members comprising  the Minister of the Hajj and the Minister of the Higher Education. This committee supervised the programmes related to the works of the HRC.

In 1998, the name of HRC was changed to the Custodian of the Two Holy Mosques Institute of Hajj Research (CTHMIHR) at Umm Al-Qura University in Makkah. CTHMIHR has five research departments. These departments are:

  1. Department of Administrative and Human Research
  2. Department of Environmental and Health Research
  3. Department of Architectural and Engineering Research
  4. Department of Information and Technical Services
  5. Department of Research and Information Affairs.

Additionally, there is the Administrative and Financial Affairs Department. CTHMIHR has a permanent exhibition, Chemical and Biological laboratory, a library, two computer laboratories and print shop, a slide archive and film archive. These archives include a large collection of colour slides and a large number of cinema, video and sound recordings covering the Hajj activities and the Holy places since HRC was established. CTHMIHR uses the available information from relevant studies to help in organizing Hajj related activities. It is the concern of the CTHMIHR to provide all possible practical solutions for the different Hajj authorities and pilgrims to guarantee their safety and comfort.

In 1999, the Oversight Committee of the Institution officially accepted the managerial structure of CTHMIHR and related departments research and units (Figure 1).  The managerial structure of CTHMIHR started with the Oversight Committee of the Institution, followed by the President of Umm Al-Qura University, followed by the Dean of CTHMIHR, followed by the Deputy Dean for Administrative Affairs, Deputy Dean for Academic  Affairs, Deputy Dean for development and community services and supervisor of Madinah branch.
