We present a detailed study of the magnetic and electronic properties of ${\mathrm{U}}_{2}{\mathrm{Rh}}_{3}{\mathrm{Si}}_{5}$, a material that has been demonstrated to exhibit a first-order antiferromagnetic phase transition. From a high-magnetic-field study, together with extensive experiments in moderate fields, we establish the magnetic phase diagrams for all crystallographic directions. The possibility of an electronic phase in a narrow interval above the N\'eel temperature as a precursor of a magnetic phase is discussed.
