Pope Martin IV
In 1271, he was once more involved in a party struggle. The minority among the "nations" chose him as rector in opposition to the elected candidate, Aubri de Rheims. For three years the strife continued, and was probably based on the opposition between the Averroists, Siger and Pierre Dubois, and the more orthodox schoolmen. The matter was settled by the Papal Legate, Simon de Brion, afterwards Pope Martin IV. Siger retired from Paris to Liège.
