Whereas on the one hand, Udham Singh Nagar is basically an industrial district and many industry related professions are prevalent here, it is perfect example of 'Unity in Diversity' for which India is so widely known, on the other hand different cultures, religions and life styles are blended in absolute harmony. The fertile land lends itself to different forms of agriculture giving  rise  to  agriculture related activities and industry making this land a green place which has resulted into prosperity all around. Pantnagar university is a leading temple of learning in the fields of agriculture and technology with one of the finest built university all around the world. This place has rare sight seeing as it is surrounded by  Kumaon Himalayas on one side and Nepal on the other (Tanakpur touches the Khatima border which is in Champawat district).NanakMatta dam, Dronasagar and many other places are worth visiting. Atariya mandir mela and Chaiti mandir mela is famous where one can find local folk activities and mingle with local culture and traditions.

In the past this land which is full of forest land was neglected till 1948 due to difficult climate. Marshy lands, extreme heat, rains which lasted months, a place full of wild animals, diseases and no means of transportation prevented the human race to form a colony here.

According to Historians, hundreds of years ago village Rudrapur was established by a devotee of lord Rudra or by Hindu tribal chief called Rudra, which has passed through phases of development to take the shape of city Rudrapur. The importance of Rudrapur has increased as it is the head quarter of district Udham Singh Nagar. During the reigns of mughal emperor Akbar this land  was handed  over   to  king Rudra Chandra  in 1588. The king established a permanent millitary camp to free tarai  from day today invasions. Totaly neglected village Rudrapur was filled with new colours and human activities. There is a saying that Rudrapur was named after king Rudra Chandra.

During the reigns of Britishers, Nainital was made a district and in 1864-65 the whole Tarai and Bhawar was put under "Tarai and Bhawar Government Act" which was governed directly by the British crown.

The history of development started with 1948, when the problem of partition brought refugee problem with it.  Immigrant from north west and eastern areas  were re-established  in 164.2 square km land area under "up nivesh yojana". Personal dwellers were not allotted land in accordance with crown grant act. The first batch of immigrants came in December 1948.

People from Kashmir, Punjab, Kerala, Eastern UP, Garhwal, Kumaon, Bengal, Hariyana, Rajasthan, Nepal, and Naidu live in groups in this districts. This country is an example of unity in diversity with people from many religions and professions and so is this Tarai, which has its heart at Rudrapur. Due to this Tarai was named MINI HINDUSTAN.
