Pathway dependence is common in self‐assembly. Here, we show the importance of pathway dependence for redox‐driven gels by constructing a Fe(II)/Fe(III) redox‐based metal‐organic gel system. We show that in situ oxidation of the Fe(II) ions at different rates results in conversion of a Fe(II)‐gel into a Fe(III)‐organic gel, which controls the material properties such as gel stiffness, gel strength, and an unusual swelling behaviour. The rate of formation of Fe(III) ions determines the extent of intermolecular interactions and so whether gelation or precipitation occurs.
