In 1848 the Parliament
of England passed the Treason Felony Act
. This law made it a high crime, punishable by exile, to write or say anything about removing the monarchy - even by peaceful means.
This law remains on the books today and a small furor was instigated by the editor of The Guardian in spring 2001 when he sought assurances from the Attorney General that he would not be prosecuted if he ran a series of articles arguing that Britain should be given the choice of whether to keep the royal family or to become a republic. The Attorney General declined to say whether prosecution might occur.
In the 1800's, the Treason Felony Act was one of the main weapons used to incarcerate Irishmen who sought independence for Ireland. In the United States during the 1790's there was a comparable law, the Sedition Act, passed under President John Adams. The Sedition Act expired in March, 1801.
