Although Mozarab merchants traded in Andalusi markets, they were neither influential nor numerous before the middle of the 12th century. This was owed to commercial disinterest and disorganization in the early Middle Ages rather than any specific or religious impediments set up by the Muslim rulers. Unlike Andalusi Muslims and Jews, Mozarabs had little interest in commerce because of their general perception of trade as lowly and despicable. This was in stark contrast to the greater respect accorded to merchants in Jewish and Muslim societies, where trade was frequently combined with other callings, such as politics, scholarship, or medicine.
