By the seventh century Constantinople was the greatest city in the Christian world: a large population center, the seat of the imperial court and administration, and the pivot of a large volume of international trade. Given that the city was a natural geographical connecting point between East and West, its markets offered goods from many parts of the world. At the end of the eleventh century Constantinople may have been the world’s third-largest city, with only Córdoba in Spain and Kaifeng in China larger.

Although merchants could become fabulously wealthy, the landed aristocracy always held the dominant social position, as in western Europe and China. Aristocrats and monasteries usually invested their wealth in real estate, which involved little risk but brought little gain.

Constantinople did not enjoy constant political stability. Between the accession of Emperor Heraclius in 610 and the fall of the city to Western Crusaders in 1204 (see “The Course of the Crusades” in Chapter 14), four separate dynasties ruled at Constantinople. Imperial government involved such intricate court intrigue, assassination plots, and military revolts that the word byzantine is sometimes used in English to mean extremely entangled and complicated politics.

The typical household in the city included family members and servants, some of whom were slaves. Artisans lived and worked in their shops, while clerks, civil servants, minor officials, and business people commonly dwelled in multistory buildings perhaps comparable to the apartment complexes of modern American cities. Wealthy aristocrats resided in freestanding mansions.

In the homes of the upper classes, the segregation of women seems to have been the first principle of interior design. As in ancient Athens, private houses contained a gynaeceum (jihn-uh-SEE-uhm), or women’s apartment, where women were kept strictly separated from the outside world. The fundamental reason for this segregation was the family’s honor.

As it was throughout the world, marriage was part of a family’s strategy for social advancement. Both the immediate family and the larger kinship group participated in the selection of a bride or a groom, choosing a spouse who might enhance the family’s wealth or prestige.
