The Union faced secessionists in eleven Southern states grouped together as the Confederate States of America.

Information: - The University of Paris, metonymically known as the Sorbonne (its historical house), was a university in Paris, France. Appearing around 1150 as a corporation associated with the Notre Dame de Paris cathedral school, it was the second-oldest modern university in Europe.

While having no known date of foundation, there is evidence of teaching as far back as 1096, making it the oldest university in the English-speaking world and the world's second-oldest university in continuous operation. It grew rapidly from 1167 when Henry II banned English students from attending the University of Paris. After disputes between students and Oxford townsfolk in 1209, some academics fled northeast to Cambridge where they established what became the University of Cambridge. The two "ancient universities" are frequently jointly referred to as "Oxbridge". - Professor Jacob Klein ( b. 1949 ) , former holder of the Herman Mark Chair of Polymer Physics in the Materials and Interfaces Department at the Weizmann Institute in Rehovot , Israel and Dr Lee 's Professor of Chemistry at the University of Oxford , is an internationally - renowned soft condensed matter , polymer and surface scientist . Klein was an undergraduate and graduate at Cambridge University and held a research fellowship and later a fellowship at St. Catharine 's College , Cambridge between 1976 and 1984 . He held a Postdoctoral Fellowship at the Department of Polymer Research , Weizmann Institute between 1977 and 1980 , after which he worked jointly as University Demonstrator with the Physics Department , Cambridge , and as a Senior Scientist at the Weizmann Institute .

He was succeeded in that position by Professor Carol Robinson . Professor Klein currently heads a research group at the Weizmann Institute of Science . - Oxbridge is a portmanteau (blend word) of the University of Oxford and the University of Cambridge in the United Kingdom. The term is used to refer to them collectively in contrast to other British universities and more broadly to describe characteristics reminiscent of them, often with implications of superior social or intellectual status.
