Abjuration

Abjuration (from Lat. abjurare, to forswear), a solemn repudiation or renunciation on oath[?]. In English common law, it signified the oath of a person who had taken sanctuary to leave the realm for ever; this was abolished in the reign of James I.

The Oath at Abjuration, in English history, was a solemn disclaimer, taken by members of parliament, clergy and laymen against the right of the Stuarts to the crown, imposed by laws of William III, George I and George III; but its place has since been taken by the oath of allegiance.
