Final results are presented from the search for magnetic monopoles and nucleon decay in the Soudan 1 detector, a 31.4-metric-ton tracking calorimeter located underground at a depth of 590 m. A detailed description of the detector is given. The possible existence of monopole catalysis of nucleon decay has been systematically incorporated into the analysis. During a live time of 1.0 yr, no candidates for grand-unified magnetic monopoles were observed, leading to 90%-confidence-level flux limits near 10-13 cm2 sec sr.
