The turnabout of Nepal's political orientation in early 1951, the eradication of malaria and the enormous flow of immigrants from the mountains (Pahariyas) induced an impressive changing process in Chitawan. The development of Chitawan from the "fever hell" to the so-called "melting pot of Nepal" has affected the way of life of the autochthonous inhabitants, the majority of whom are Tharus, drastically. For the period of 1920 to 1981 the population of Chitawan has increased by its thirteenfold, the Tharus became a minority, sharing their more and more limited living space with the growing number of immigrants of different ethnic groups.
To elucidate in a few examples what has dissolved and what has resisted as aggregat in this "melting pot" the Tharu and Pahariya house exposition concept as well as their style of agriculture are compared. Focussing on the question of the Tharus' response to the recently raised multiethnical constellation the interethnical notions and clichés are summarized.
