 So in March 313 Licinius married Flavia Julia Constantia, half-sister of Constantine I, at Mediolanum (now Milan); they had a son, Licinius the Younger, in 315.Their marriage was the occasion for the jointly-issued "Edict of Milan" that reissued Galerius' previous edict allowing Christianity (and any religion one might choose) to be professed in the Empire, with additional dispositions that restored confiscated properties to Christian congregations and exempted Christian clergy from municipal civic duties.The redaction of the edict as reproduced by Lactantius - who follows the text affixed by Licinius in Nicomedia on 14 June 313, after Maximinus' defeat - uses neutral language, expressing a will to propitiate "any Divinity whatsoever in the seat of the heavens".
