The striving of countries in Central Europe to enter the European Union may offer an unprecedented chance to the continent’s Gypsies (or Roman) to be recognized as a nation, albeit one without a defined territory. And if they were to achieve that they might even seek some kind of formal place-at least a total population outnumbers that of many of the Union’s present and future countries. Some experts put the figure at 4m-plus; some proponents of Gypsy rights go as high as 15m.
