* Clarification regarding 1149 declaration: At this date, the relations between Rome and Constantinople were at their finest moment since the restoration of the WRE in 800. De facto, they shared their sovereignty over diverse territories like Hungaria (the remaining Magyar Empire), Serbia and the most important, the Holy Land. By Roman side, the Emperor realized the increasing Byzantine dependency on the Roman military assistance. If Rome was apparently due to assume the control of the Byzantine borders in order to stop the hard pressure of the Turks, it would be better to assume a joint control. Obviously, this was still too premature. In Constantinople, even if they were aware on this increasing dependency on Rome, the elites did not want to lose their status or relocate to Pavia in order to keep their influence in the Imperial power. And also the Roman dukes were reluctant to incorporate such large territory with their own cultural and political particularities.
