Council of ConstanceThe Council of Constance (Concilium Constantiense; Konzil von Konstanz) was an ecumenical council of the Catholic Church that was held from 1414 to 1418 in the Bishopric of Constance (Konstanz) in present-day Germany. The council ended the Western Schism by deposing or accepting the resignation of the remaining papal claimants and by electing Pope Martin V. It was the last papal election to take place outside of Italy.
CensusA census is the procedure of systematically acquiring, recording and calculating population information about the members of a given population. This term is used mostly in connection with national population and housing censuses; other common censuses include censuses of agriculture, traditional culture, business, supplies, and traffic censuses. The United Nations (UN) defines the essential features of population and housing censuses as "individual enumeration, universality within a defined territory, simultaneity and defined periodicity", and recommends that population censuses be taken at least every ten years.
Colonna familyThe House of Colonna, also known as Sciarrillo or Sciarra, is an Italian noble family, forming part of the papal nobility. It was powerful in medieval and Renaissance Rome, supplying one pope (Martin V) and many other church and political leaders. The family is notable for its bitter feud with the Orsini family over influence in Rome, until it was stopped by papal bull in 1511. In 1571, the heads of both families married nieces of Pope Sixtus V.
Albertus MagnusAlbertus Magnus (1200 – 15 November 1280), also known as Saint Albert the Great or Albert of Cologne, was a German Dominican friar, philosopher, scientist, and bishop. Later canonized as a Catholic saint, he was known during his lifetime as Doctor universalis and Doctor expertus and, late in his life, the sobriquet Magnus was appended to his name. Scholars such as James A. Weisheipl and Joachim R. Söder have referred to him as the greatest German philosopher and theologian of the Middle Ages.
