Koschorke, Martin supported colonial expansion. Davidson (1961) argues that Martin's injunction against slavery was not a condemnation of slavery itself, but rather driven through fear of "infidel power". Norman Housley finds it "...hard to avoid the conclusion that the pope was agreeing to whatever was asked of him by the king.... [P]olitical weakness compelled the Renaissance Papacy to adopt an acquiescent and unchallenging position when approached for requests for privileges in favour of these ventures." Residences During his permanence in Rome, Martin moved his residence from the Lateran to Santa Maria Maggiore and, from 1424, the Basilica of Santi Apostoli near the Palazzo Colonna. He also frequently sojourned in towns held by his family in the Latium (Tivoli, Vicovaro, Marino, Gallicano and others). Numbering When the second Pope to take the name Martin was elected in 1281, there was confusion over how many Popes had taken the name before. It was believed then that there were three, so the new Pope of 1281 became Martin IV. But, in reality, those believed to be Martin II and Martin III were actually named Marinus I and Marinus II, although they are sometimes still referred to as "Martin II" and "Martin III". This has advanced the numbering of all subsequent Popes Martin by two. Popes Martin IV–V were actually the second and third popes by that name.
