The University of Delaware is one of the oldest first-class universities in America. Its history can be traced back to 1743. At first, it was a small private academic institution, until 1833, it was transformed into a public university due to government grants and land grants. The University of Delaware has seven colleges, whose strong majors include engineering (chemistry, biomedicine, machinery, civil engineering and electricity), business (accounting, business administration, finance, hotel industry, catering industry and institutional management), science (agriculture and natural resources, biology, chemistry, marine science and physics), physical therapy and art preservation. The main reason is the history here.
