Their function in the state was twofold, to supply the crown at any moment with ready money, and to act as a channel for the conveyance to the king of the property of his subjects. The degree of their usefulness must be gauged by the provisions of their charter (No. 1). It is reasonable to suppose that their expulsion was only determined on when the crown had drained their resources, or when, as was the case, there were other supplies available from a class of financiers less obnoxious to the racial and religious prejudices of the age. The place of the Jews was immediately occupied by the merchants of Lucca, and later by the Friscobaldi, the Bardi and Peruzzi and other wealthy societies of Italian merchant-bankers. AUTHORITIES The principal modern writers dealing with the subject in this section are:--Jacobs, _The Jews in Angevin England_; Jacobs, _London Jewry_ (Anglo-Jewish Exhibition Papers); Gross, _Exchequer of the Jews_ (Anglo-Jewish Exhibition Papers); Rigg, _Select Pleas of the Exchequer of the Jews_ (Selden Society); Rye, _Persecution of the Jews in England_ (Anglo-Jewish Exhibition Papers); Abrahams, _The Expulsion of the Jews from England_. 1. CHARTER OF LIBERTIES TO THE JEWS[80] [_Charter Roll, 2 John, m._ 5.], 1201. John by the grace of God, etc. Know ye that we have granted to all Jews of England and Normandy that they may freely and honourably reside in our land, and hold of us all things that they held of King Henry, our father's grandfather, and all things that they now hold reasonably in their lands and fees and pawns and purchases, and that they may have all their liberties and customs as well and peaceably and honourably as they had them in the time of the aforesaid King Henry, our father's grandfather. And if a plaint shall have arisen between Christian and Jew, he who shall have appealed the other shall have witnesses for the deraignment of his plaint, to wit, a lawful Christian and a lawful Jew. And if the Jew shall have a writ touching his plaint, his writ shall be his witness; and if a Christian shall have a plaint against a Jew, it shall be judged by the Jew's peers. And when a Jew be dead, his body shall not be detained above ground, but his heir shall have his money and his debts; so that he be not disturbed thereon, if he have an heir who will answer for him and do right touching his debts and his forfeit. And it shall be lawful for Jews without hindrance to receive and buy all things which shall be brought to them, except those which are of the Church and except cloth stained with blood. And if a Jew be appealed by any man without witness, he shall be quit of that appeal by his bare oath upon his Book. And in like manner he shall be quit of an appeal touching those things which pertain to our crown, by his bare oath upon his Roll. And if there shall be dispute between Christian and Jew touching the loan of any money, the Jew shall prove his principal and the Christian the interest.
