The Treaty of Granada, signed in 1491, granted certain rights to the Mudéjars, who were Muslims living under Christian rule after the Reconquista. The treaty allowed them to worship freely as Muslims and keep their cultural practices, at least temporarily. However, this tolerance was not upheld long-term, and eventually, many Mudéjars faced increasing pressure to convert to Christianity and were subjected to various restrictions.
From the options provided, the most accurate statement is: They were allowed to worship freely as Muslims, at least initially as part of the treaty's terms. However, this status ultimately changed with later laws and social pressures.
