There were a great deal of problems between these groups. Zamenhof felt that the language difference between the groups was the root of the problem. This gave him the idea of creating a language that would not belong to any one country or culture, but instead, would belong equally to all people. The hope was that a neutral second language would break down language barriers and build a sense of equality and brotherhood beween nations. The language which he created to fulfill this dream was called Esperanto, which means hope in th Esperanto language.
