Angeliki Laiou (1941-2008), one of the leading Byzantinists of her generation, broke new ground in the study of the social and economic history of the Byzantine Empire. Byzantium and the Other: Relations and Exchanges, the second of three volumes to be published posthumously in the Variorum Collected Studies Series, brings together fourteen articles published between 1982 and 2012 that reflect her enduring interest in Byzantium's political, ideological, and commercial relations with its neighbours. The first three articles examine Byzantine attitudes and institutional responses to foreigners and strangers within the empire, while the next four concern Byzantium's response to the Crusades and, more generally, to questions of justice in the spheres of conflict and colonisation. The final seven articles investigate Byzantium's political and commercial relations with other regional and Mediterranean powers; particular emphasis is placed on Venice and Genoa, whose increasing involvement in the Byzantine economy so marked the final centuries of the empire's existence.
