Questions of tithes (or "teinds ") and ministers' stipends were referred to commissioners by acts of the Scots parliaments beginning in 1607.
By a statute of 1633 landholders were enabled to have their tithes valued, and to buy them either at nine or six years' purchase, according to the nature of the property.
They built up great estates, especially in the principality of Tripoli; they quarrelled with one another, until their dissensions prevented any vigorous action; they struggled against the claims of the clergy to tithes and to rights of jurisdiction; they negotiated with the Mahommedans as separate powers; they conducted themselves towards the kings as independent sovereigns.
Tithes for the Crusades were first imposed on the clergy by Innocent III.
The refusal to pay tithes and other ecclesiastical demands led to continuous and heavy distraints, under the various laws made in that behalf.
