Chaldean Catholic Territory Dependent on the Patriarch of Jerusalem

The Chaldean Catholic Territory Dependent on (or Patriarchal Dependency of) the Patriarch of Jerusalem is a missionary pre-diocesan jurisdiction of the Chaldean Catholic Church "sui iuris" (Eastern Catholic: Chaldean Rite, Syriac language) covering the Holy land (Palestine and Israel).
As Territory Dependent on the Patriarch, it is immediately subject to the Chaldean Catholic Patriarch of Babylon (actually in Baghdad, Iraq), without being part of his or any other ecclesiastical province. 
It is not entitled to a (Titular) Bishop as Ordinary, the incumbents use the style Protosyncellus (normally an official in an episcopal curia).
History.
