 THE TURKISH ADVANCE. 307 the Turks as treating the peasants kindly, promising them free- dom, and thus winning them over, and he adds that the mag- nates cannot defend their castles when thus abandoned by the peasants.* As regards the Cathari, the Turkish advance produced two contrary effects. On the one hand there was the danger that per- secution would drive them to seek protection from the enemy. On the other hand there was absolute need of assistance from Christendom, which could only be obtained by submission to Kome, and obedience to her demands for their extermination. Both of these influences worked to the destruction of Bosnia, for when toleration was practised aid was withheld, and when at last perse- secution was established as a policy the Cathari welcomed the invader, and contributed to the subjugation of the kingdom. In 1420 Stephen Tvrtko II. reappeared upon the scene, and the next year he was acknowledged.
