Pope Honorius IV (c. 1210 – April 3, 1287), born Giacomo Savelli, was Pope for two years from 1285 to 1287. During his unremarkable pontificate he largely continued to pursue the pro-French policy of his predecessor, Pope Martin IV (1281–85). He was the last Pope who was married before he took Holy Orders.
Savelli was born in Rome, into the rich and influential Roman family of the Savelli. Initially, he was married and had at least two sons. One of them became podesta of Urbino and died before 1279, and another one was senator in Rome and died in 1306. After the death of his wife, he entered ecclesiastical state.

In 1274 he accompanied Gregory X to the Council of Lyon where it was established that only four mendicant orders were to be tolerated: Dominicans, Franciscans, Augustinians and Carmelites. In July, 1276, he was one of the three cardinals whom Pope Adrian V (1276) sent to Viterbo with instructions to treat with the German King, Rudolf I of Habsburg (1273–1291), concerning his imperial coronation at Rome and his future relations towards Charles of Anjou, who...
