In the Scottish church of the 18th and 19th centuries, a burgher was a person who upheld the lawfulness of the Burgher Oath.[1][2]
The Burgher Oath was the oath that a town burgess was required to swear on taking office.[3]
The Burghers' position was in opposition to the Seceders and Anti-Burghers.
A member of that party, among the Scotch seceders, which asserted the lawfulness of the burgess oath (in which burgesses profess the true religion professed within the realm"), the opposite party being called antiburghers.
