Burschenschaft \Bur"schen*schaft`\, n.; pl. -schaften. [G.]
   In Germany, any of various associations of university
   students formed (the original one at Jena in 1815) to support
   liberal ideas, or the organization formed by the affiliation
   of the local bodies. The organization was suppressed by the
   government in 1819, but was secretly revived, and is now
   openly maintained as a social organization, the restrictive
   laws having been repealed prior to 1849. --
