Reichstag
The electors, like the other princes ruling States of the Empire, were members of the Reichstag, which was divided into three collegia: the Council of Electors, the Council of Princes, and the Council of Cities. In addition to being members of the Council of Electors, several lay electors were therefore members of the Council of Princes as well by virtue of other territories they possessed. In many cases, the lay electors ruled numerous States of the Empire, and therefore held several votes in the Council of Princes. In 1792, the King of Bohemia held three votes, the Elector of Bavaria six votes, the Elector of Brandenburg eight votes, and the Elector of Hanover six votes. Thus, of the hundred votes in the Council of Princes in 1792, twenty-three belonged to electors. The lay electors therefore exercised considerable influence, being members of the small Council of Electors and holding a significant number of votes in the Council of Princes. The assent of both bodies was required for important decisions affecting the structure of the Empire, such as the creation of new electorates or States of the Empire.
In addition to voting by colleges or councils, the Reichstag also voted on religious lines, as provided for by the Peace of Westphalia. The Archbishop of Mainz presided over the Catholic body, or corpus catholicorum, while the Elector of Saxony presided over the Protestant body, or corpus evangelicorum. The division into religious bodies was on the basis of the official religion of the state, and not of its rulers. Thus, even when the Electors of Saxony were Catholics during the eighteenth century, they continued to preside over the corpus evangelicorum, since the state of Saxony was officially Protestant.
