The date of this law is uncertain, but it presupposes a considerable anterior period of toleration, during which Jews had multiplied and had become possessed of landed wealth. To what extent it may have been enforced we have no means of knowing, but its observance must only have been temporary, for such glimpses as we get of the condition of the Jews up to the fourteenth century are wholly incompatible with the fierce proscription of the Gothic laws. As the Spanish kingdoms organized themselves, the Fuero Juzgo for the most part was superseded by a crowd of local fueros, _cartas-pueblas_ and customs defining the franchises of each community, and we have seen in the preceding chapter how in these both Moor and Jew were recognized as sharing in the common rights of citizenship and how fully the freedom of trade between all classes was permitted. In 1251 the Fuero Juzgo was formally abrogated in Aragon by Jaime I, who forbade it to be cited in the courts--a measure which infers that it had practically become obsolete.[250] In Castile it lingered somewhat longer and traces of its existence are to be found in some places until the end of the thirteenth century.[251] These, however, are not to be construed as referring to the provisions respecting Jews, which had long been superseded. In fact, the Jews formed too large and important a portion of the population to be treated without consideration. The sovereigns, involved permanently in struggles with the Saracen and with mutinous nobles, found it necessary to utilize all the resources at their command, whether in money, intelligence, or military service. In the first two of these the Jews stood pre-eminent, nor were they remiss in the latter. On the disastrous field of Zalaca, in 1086, forty thousand Jews are said to have followed the banner of Alfonso VI, and the slaughter they endured proved their devotion, while, at the defeat of Ucles in 1108, they composed nearly the whole left wing of the Castilian host.[252] In 1285 we hear of Jews and Moors aiding the Aragonese in their assaults on the retreating forces of Philippe le Hardi.[253] As regards money, the traffic and finance of Spain were largely in their hands, and they furnished, with the Moors, the readiest source from which to derive revenue. Every male who had married, or who had reached the age of 20, paid an annual poll tax of three gold maravedís; there were also a number of imposts peculiar to them, and, in addition, they shared with the rest of the population in the complicated and ruinous system of taxation--the ordinary and extraordinary _servicios_, the _pedidas_ and _ayudas_, the _sacos_ and _pastos_ and the _alcavalas_. Besides this they assisted in supporting the municipalities or the lordships and prelacies under which they lived, with the _tallas_, the _pastos_, the ninths or elevenths of merchandise and the _peajes_ and _barcajes_, the _pontazgos_ and _portazgos_, or tolls of various kinds which were
