ABSTRACT
Currency zones are the first and the most obvious form of monetary integration. The simplest monetary unions were formed very soon after money as such had appeared. While the first coins were minted in the seventh century B.C. in Lydia (Asia Minor) policies of Ancient Greece already agreed on mutual circulation of their coins in the sixth century B.C. Such a union, for example, was founded by cities of Boeotia in Central Greece. During Caesar’s rule (middle of the first century B.C.) the western part of the Roman empire actually became a zone of the Roman Denari. The subsequent history of monetary unions can be traced from the Hanseatic monetary union of the fourteenth century, to Latin and Scandinavian unions of the second half of the nineteenth century and to the modem Economic and Monetary Union of the EU.
