This volume seeks to foreground a ampampldquoborderlessampamprdquo history and geography of South Southeast and East Asian littoral zones that would be maritimefocused and thereby explore the ancient connections and dynamics of interaction that favoured the encounters among the cultures found throughout the region stretching from the Indian Ocean littorals to the Western Pacific from the early historical period to the present. Transcending the artificial boundaries of macroregions and nationstates and trying to bridge the arbitrary divide between inherently cosmopolitan ampampldquohighampamprdquo cultures e.g. Sanskritic Sinitic or Islamicate and ampampldquolocalampamprdquo or ampampldquoindigenousampamprdquo cultures this multidisciplinary volume explores the metaphor of Monsoon Asia as a vast geoenvironmental area inhabited by speakers of numerous language phyla which for millennia has formed an integrated system of littorals where crops goods ideas cosmologies and ritual practices circulated on the searoutes governed by the seasonal monsoon winds.
