Historically, because of its strategic position and its excellent deep-water port, the city was fiercely contested, especially among Italy, Hungary, and Croatia, changing hands and demographics many times over centuries. According to the 2011 census data, the overwhelming majority of its citizens are Croats, along with small numbers of Bosniaks, Italians and Serbs. The city has a strong local sense of identity and the autochthonous inhabitants of Rijeka are referred to as Fiumans.

Zajc, first built in 1765, as well as the University of Rijeka, founded in 1973 but with roots dating back to 1632 School of Theology.
