西班牙再征服时代，穆斯林国家和基督教国家争夺伊比利亚半岛。宗教、民族分立这一独特的政治环境使犹太人能够生活在较为宽松的环境中，发挥他们在经济方面的长处。他们能从事多种经济活动，比如商业、农业、收税等。而对犹太人征的税也成为统治者主要收入来源之一。通过借钱给统治者亦或是为统治者管理财富，他们由此身居高位。经济方面的实用性使他们得以获得统治者的庇护。但是当再征服结束后，极端宗教情绪兴起，以及基督教徒在商业方面的发展，使得犹太人对统治者的吸引力下降，犹太人的金钱则失去了原先的吸引力，无法继续庇护他们。1492年，犹太人被驱逐出了西班牙。

In the era of Spanish Reconquista, Muslim countries and Christian countries went to war over the Iberian Peninsula. The peculiar political circumstance of multi-religion and multi-race provided for the Jews a comparatively tolerant environment. Exerting their talent in economy, they devoted themselves into many economic aspects, such as trade, agriculture and tax collection. And the taxes collected from the Jews were one of the main incomes of the king’s treasury. By means of loaning to the king or managing the king’s treasury, Jews could be promoted to a high rank. It’s their utility in economy that bought them the shelter from the kings. However, at the end of the Reconquista, with the extremism in Christian arising and achievement in trade made by Christians, kings’ appeal for Jews and their money was greatly decreased and the shelter for them was taken back. In the year of 1492, Jews was expulsed from Spain.
