Cassare or calissare (from Portuguese casar, "to marry") was the term applied to the marriage alliances, largely in West Africa, set up between European and African slave traders; the "husband" was European and the wife/concubine African. This was not marriage under Christian auspices, although there might be an African ceremony; there were few clerics in equatorial Africa, and the "wives" could not marry since they had not been baptized. Male monogamy was not expected. As such, concubinage is a more accurate term. The multinational Quaker slave trader and polygamist, Zephaniah Kingsley purchased the Wolof princess, Anna Kingsley, who had earlier been enslaved and sold in Cuba, after being captured in modern-day Senegal.
