Crusade and jihad converged on tolerating alien religions only as subjects.

Evidence

The doctrines of Crusade and jihad here approximate, first, in the willingness to tolerate people of an alien religion only as subjects (though their status within Christendom in theory and practice was less safe than in Islam); in the direction of holy war against all kinds of rebels and dissenters; and in the insistence on duly constituted authority for waging war. โ€” Norman Daniel, Islam and the West, 1823 (#expands, via linked claim)

This freedom of religion was not granted toward pagan idolaters. Apart from the brief episode of the satanic verses, Muslim doctrine on idolatry is clear: it is evil. Idols must be eliminated, and Muslim troops often destroyed them and their temples. โ€” John V. Tolan, Saracens, 244 (#qualifies, via linked claim)

It may simplistically be argued that the law of jihad is legal knowledge used by political and military power, but this argument encounters significant problems. First, understood properly, this law was in effect mostly defensive rather than offensive. Jihad is mandatory only when the lands of Islam are attacked by the enemy, and only those in relative proximity to the territory attacked are obligated to partake in the defense, not all Muslims within the kingdom or principality. โ€” Wael Hallaq, Restating Orientalism, 682 (#qualifies, via linked claim)
