the Byzantine Empire by seeking peace everywhere that it was possible—his dealings with Bulgaria and Kievan Rus' have been described above. To protect Byzantine Thrace from Magyar incursions (such as the ones in 934 and 943), Romanos paid them protection money and pursued diplomatic avenues. The Khazars were the allies of the Byzantines until the reign of Romanos, when he started persecuting the Jews of the empire. According to the Schechter Letter, the Khazar ruler Joseph responded to the persecution of Jews by "doing away with many Christians", and Romanos retaliated by inciting Oleg of Novgorod (called Helgu in the letter) against Khazaria. Similarly, Romanos re-established peace within the church and overcame the new conflict between Rome and Constantinople by promulgating the Tomos of Union in 920. In 933 Romanos took advantage of a vacancy on the patriarchal throne to name his young son Theophylaktos patriarch of Constantinople. The new patriarch did not achieve renown for his piety and spirituality, but he added theatrical elements to the Byzantine liturgy and was an avid horse-breeder, allegedly leaving mass to tend to one of his favorite mares when she was giving birth. Romanos was active as a legislator, promulgating a series of laws to protect small landowners from being swallowed up by the estates of the land-owning nobility (dynatoi). The legislative reform may have been partly inspired by hardship caused by the famine of 927 and the subsequent semi-popular revolt of Basil the Copper Hand. The emperor also managed to increase the taxes levied on the aristocracy and established the state on a more secure financial footing. Romanos was also able to effectively subdue revolts in several provinces of the empire, most notably in Chaldia, the Peloponnese, and Southern Italy. In Constantinople, he built his palace in the place called Myrelaion, near the Sea of Marmara. Beside it Romanos built a shrine which became the first example of a private burial church of a Byzantine emperor. Moreover, he erected a chapel devoted to Christ Chalkites near the Chalke Gate, the monumental entrance to the Great Palace. End of the reign Romanos' later reign was marked by the old emperor's heightened interest in divine judgment and his increasing sense of guilt for his role in the usurpation of the throne from Constantine VII. On the death of Christopher, by far his most competent son, in 931, Romanos did not advance his younger sons
