Haven't yet read the article in full (though I am familiar with the murderous medieval Tartar raids in Poland), but last summer, I visited the Tartar[0] village of Kruszyniany in northeastern Poland. During the tour of the local mosque[1], the Tartar tour guide touched on Polish-Tartar relations over the centuries. When asked by Crimean Tartars why they fought against their brothers in the faith (under the Catholic Polish banner, no less), the Polish Tartars responded that they do not fight them as brothers, but as thieves and robbers. In other words, the Lipka Tartars also have a long tradition of loyalty to one European state, the Polish-Lithuanian Commonwealth (and its successor states). The meaning of that loyalty, and in the broader Islamic context, would be an interesting thing to understand, but for some Muslims, their loyalty has been baffling, perhaps even offensive.
