Erik Sparre

Erik Larsson Sparre (born Erik Larsson; also known as Erik Gyllensparre, Eric Sparre, or Erik Sparre of Rossvik;; historically (see )}} 13 July 1550 – 20 March 1600) was a Swedish noble, statesman, diplomat, and political theorist who served as Privy Councilor from 1575 or 1576 until 1590 and Lord High Chancellor of Sweden from 1593 until his execution in 1600.

An esteemed orator and rhetorician, Sparre was considered the spokesman for the well-organized aristocratic opposition who advocated for parliamentary sovereignty in the Swedish government and is largely remembered for his contributions to Swedish law. His major written work – ('For the Law, the King, and the People') – remains highly-regarded as an early defense of contractualism and earned him a reputation as the "father of Swedish constitutional law". Sparre's ideas were initially backed by John III of Sweden in order to check the ambitions of his brother, Duke Charles, but relations between Sparre and John soured when the nobility was able to overrule the king's prerogative during a stand-off in Reval.

Sparre's diplomatic career was long and varied. He had early successes negotiating with the Danes in border disputes and helped to secure Sigismund III Vasa's accession to the Polish throne. During the discussions of Sigismund's election, Polish and Swedish tensions heightened after a misunderstanding about the annexation of Estonia, a fault that was blamed on Sparre. Following the death of John in 1592, Sparre backed Sigismund's attempt to secure the Swedish crown from Charles, but failed to secure significant material gain from potential allies abroad. After Sigismund's defeat, Sparre was convicted of treason during a show trial and beheaded during the Linköping Bloodbath. Provided by Wikipedia
