A majority of Jews were forcibly converted to Catholicism during the 14th and 15th centuries and those remaining were expelled from Spain in 1492. The open practice of Islam by Spain's sizeable Mudejar population was similarly outlawed. Furthermore, between 1609 and 1614, a significant number of Moriscos— (Muslims who had been baptized Catholic) were expelled by royal decree. Although initial estimates of the number of Moriscos expelled such as those of Henri Lapeyre reach 300,000 moriscos (or 4% of the total Spanish population), the extent and severity of the expulsion has been increasingly challenged by modern historians. Nevertheless, the eastern region of Valencia, where ethnic tensions were highest, was particularly affected by the expulsion, suffering economic collapse and depopulation of much of its territory.
