Conclavist claimant to papacy

Conclavism is the practice that has existed since the second half of the 20th century which consists in the convening of a pseudo-conclave to elect rival popes (antipopes) to the current pope of Rome. This method is used by some schismatic Catholics, often Sedevacantists, who do not accept the legitimacy of their present papacy. Those who hold the position that a conclave can be convened to elect an antipope to contest or rival the current Bishop of Rome are called conclavists.
