 (IET). Before the merger the IIE had approximately 40,000 members. The IET is now the second largest engineering society in the world next to the IEEE. The IET has the authority to establish professional registration of engineers through the Engineering Council. The IEEE does not have the authority to replicate the registration process in its complementary environment.

History

The IIE traces its heritage to the Vulcanic Society that was founded in 1884. This society became the Junior Institution of Engineers in 1902, which became the Institution of General Technician Engineers in 1970 and the Institute of Mechanical and General Technician Engineers (IMGTechE) in 1976. In 1982 the IMGTechE and Institution of Technician Engineers in Mechanical Engineering (ITEME) merged to form the Institution of Mechanical Incorporated Engineers (IMechIE)

The Institution of Electrical and Electronic Incorporated Engineers (IEEIE) and the Society of Electronic and Radio Technicians (SERT) merged in 1990 to form the Institution of Electronics and Electrical Incorporated Engineers (IEEIE).

The IIE was formed in April 1998 by the merger of the IMechIE , the IEEIE and The Institute of Engineers and Technicians (IET). In 1999 The Institution of Incorporated Executive Engineers (IIExE) merged with the IIE.

In October 2001, IIE received a Royal Charter
