Having established political uniformity in Anatolia, the Seljuq sultans increased their building activities and developed trade. Having secured the routes, they lived in luxury palaces built with the aim of living in an Earthly Paradise. A Turkish-Islamic state, the Anatolian Seljuqs developed an artistic style rooted in the heritage of the many civilisations of Asia and Anatolia, and inspired by contemporary as well as Byzantine culture. During their rule, from the second half of the 5th / 11th to the early 8th / 14th centuries the Anatolian Seljuqs built monuments to suit their religious beliefs as well as their social aspirations. These included mosques, türbes (tombs), madrasas (religious schools), hammams (bathhouses), hans (caravanserai), and bridges.
