The United Nations Economic Commission for Europe was formed in 1947, and their first major act to improve transportation was the joint UN declaration numbered 1264. Signed in Geneva on September 16, 1950, it was named the Declaration on the Construction of Main International Traffic Arteries, which defined the first E-road network. This declaration was amended several times before November 15, 1975, when it was replaced by the European Agreement on Main International Traffic Arteries (AGR), which established a route-numbering system and improved standards for roads on the list. The AGR went through several changes, the last one of which, as of 2011, occurred 2008. Reorganization of the E-roads network of 1975 and 1983 defined the E751 road and assigned it to Rijeka–Pula–Koper route.

Since the first section of the Istrian Y, which constitutes the bulk of the E751 route, started in 1976, with the first section opening in 1981, there were no high-performance road routes in Istria. Instead, the E751 was signposted along state roads, specifically the D66 spanning Rijeka and Pula, and then switched to the D21 in Pula all the way to the Kaštel border crossing. As the Istrian Y system was being developed, the E751 designation was gradually transferred to the new route, with consistent signposting of the E751 along the A9 and the A8, just as the D3 state road designation west of Rijeka was transferred to the B8 and B9 (later replaced by the A8 and A9 respectively).
