This research is concerned with issues of security and protection of the newly established institutions in the Trucial States before by the Union, from 1955 to 1971, during which period of time the sheikhs and officials began to be interested in security issues and the provision of means to preserve the first institutions within each emirate. This was only able to be done by creating a police service, which would be assigned the tasks of oversight and defense.

Each emirate paid attention to this important sector and worked to implement its plans. Dubai was a pioneer in formulating the initial structure of a security institution and in qualifying police officers who would guard the emerging institutions, manage and maintain security in various parts of the Emirate, then the rest of the other emirates followed suit; therefore, such a protective structure appeared successively in Abu Dhabi, Sharjah, Ras Al Khaimah, Ajman, Umm Al Quwain, and Fujairah.

The research also focuses on pursuing the development of these institutions and their various branches and structures, from their emergence to the establishment of the Union, and the number of the Union's supervisors, including foreign experts, most of whom were British, the citizens who helped them. The research does not neglect any of the affairs of security institutions, as it provides all the statistics related to employees, such as clothing, salaries, grants, equipment, and more.

Although there is a scarcity of documentary sources and despite the lack of interest in this field, the research includes most of the sources, extracts their most prominent components and contents, and mentions lists of names of employees in this sector, their ranks, salaries, and their career and social status.
