Translation of "Etnias" in English

Os congressos representavam para ele as horas mais luminosas de todo um longo e inexpressivo ano. Era uma semana de sonho realizado, passada entre pessoas de todas as etnias, num convívio fraternal de base neutra.

The gatherings meant to him the brightest of hours of a long and isolating year. It was a "dream come true" week, spent between people of all races, in a neutral but friendly environment.
