Hey, Im from spanish, especially from Andalusia and I'm just historian, and cassually I was watching this subrredit.

First of all, sorry for my english. After that, I must say yes. I mean of course we had a pacific coexistence. You must think about that. Muslims and christians lived in the same territory and which didn't have one usually got the other. So the relations must be good for the commerce.

That's just an example of a daily coexistence, but indeed, there is other reason more powerful. Against the typical idea about the eternal fight between those cultures, the reality in three points of the Mediterranean Sea was very different. Those places are the Iberian Peninsula (Spain-Ptgl) the Italic Peninsula and Near Orient. Why? Those places are where those both cultures coexist together and were they really know about the other. The typical vision of this idea comes from the north Europe were people didn't have real contact with the Muslims.

About the Jews, well... Their history is more complicated, but in longs periods the all coexist, Jews too.

Examples of the respect are for example the Alhambra or the Cordoba's Mosque, which after the Christian conquest still stand, they didnd destroy them.

For a better knowledge about this subject you can reach one of the best spanish medievalist, Juan Vernet: "Convivencia en Al-Andalus" not in English, sorry.

Classic historian's answer: sort of.

Even Castro acknowledged that there was inter-religious discord. And it's certainly a term that deserves to be complicated, or in academic parlance, "problematized"...but nevertheless, some sense of generally functional "co-existence" existed in medieval Iberia.

You can look at this at a few scales. The first, and largest, is the political. While there was certainly more ease in creating political alliances and treaties with fellow Christian nations (or Muslim, as the case may be)--given shared language, shared religion and culture--Christian kings certainly did ally with Muslim kings, even at times against coreligionists. And more often than alliances, there were periods, sometimes quite lengthy, of peace treaties between belligerents--Granada was a vassal of Castile for 250 years before its fall at the end of the 15th century (though war periodically broke out during that time, but never for long). However, of course there was plenty of inter-religious war--crusades, in fact. The same rhetoric that was applied in the Middle East occurred in Iberia, indicating that "tolerance" only went so far.

The second scale is communal. Religious communities at the local level managed to interact with relative ease regularly throughout the peninsula, but it was by no means universal or static. David Nirenberg, in his Communities of Violence, talks about the "systemic violence" that served to maintain boundaries, and therefore peace, between the Christian majority and the Jewish and Muslim minorities in later medieval Aragon. Annual rituals of throwing rocks at the Jewish quarter during Holy Week, for example, reminded everyone where the power lay and that Jews and Christians were not equals. However, these communities could still buy and sell (with restrictions) and get along well enough, so long as they respected these boundaries.

The third scale is the individual. We have quite a few laws from the medieval period restricting the interaction of people based on their religion--in particular regarding sexual interaction. However, as with any laws, we should never say "X was illegal, so it wasn't done." Instead: "they had to keep making rules about X because people kept doing it." Sex between Muslim men and Christian women, or Jewish women and Christian men, or whatever combination, is evidenced through many court cases in Christian Iberia. And it wasn't just Christians who were offended by it--rabbis and imams too demanded that Christian authorities make sure their sexual boundaries were maintained. Minorities (or, at least their authorities) were interested in keeping clear cultural autonomy and distinction from the majority.

So in short, convivencia, if defined as a general propensity to successfully manage co-existence among Christians, Muslims, and Jews, while acknowledging that this co-existence was not all rainbows and smiles and allowing for plenty of exceptions, did happen in medieval Iberia.
