Zamenhof's reasons for making Esperanto strike a chord with me. A quote of a quote, from wikipedia:
Esperanto was created in the late 1870s and early 1880s by L. L. Zamenhof, a Polish-Jewish ophthalmologist from Biaystok, then part of the Russian Empire. According to Zamenhof, he created the language to foster harmony between people from different countries. His feelings and the situation in Biaystok may be gleaned from an extract from his letter to Nikolai Borovko:
"The place where I was born and spent my childhood gave direction to all my future struggles. In Biaystok the inhabitants were divided into four distinct elements: Russians, Poles, Germans and Jews; each of these spoke their own language and looked on all the others as enemies. In such a town a sensitive nature feels more acutely than elsewhere the misery caused by language division and sees at every step that the diversity of languages is the first, or at least the most influential, basis for the separation of the human family into groups of enemies. I was brought up as an idealist; I was taught that all people were brothers, while outside in the street at every step I felt that there were no people, only Russians, Poles, Germans, Jews and so on. This was always a great torment to my infant mind, although many people may smile at such an 'anguish for the world' in a child. Since at that time I thought that 'grown-ups' were omnipotent, so I often said to myself that when I grew up I would certainly destroy this evil."
—L. L. Zamenhof, in a letter to Nikolai Borovko, ca. 1895
