We always hear about the evil of the Crusades and the righteous indignation of Muslims over a series of wars that provide a poor witness to the Gospel. However, was Islam an innocent victim, or were the crusades a response to a long series of Muslim religious conquest of Christian lands and oppression of Christian believers?

Take a look at the timeline and decide. I'll put Muslim jihad against Christian lands in bold, and Christian assaults on Islamic lands in italics.

630 Two years before Muhammad’s death of a fever, he launches the Tabuk Crusades, in which he led 30,000 jihadists against the Byzantine Christians. He had heard a report that a huge army had amassed to attack Arabia, but the report turned out to be a false rumor. The Byzantine army never materialized. He turned around and went home, but not before extracting “agreements” from northern tribes. They could enjoy the “privilege” of living under Islamic “protection” (read: not be attacked by Islam), if they paid a tax (jizya).

This tax sets the stage for Muhammad’s and the later Caliphs’ policies. If the attacked city or region did not want to convert to Islam, then they paid a jizya tax. If they converted, then they paid a zakat tax. Either way, money flowed back to the Islamic treasury in Arabia or to the local Muslim governor.

632-634 Under the Caliphate of Abu Bakr the Muslim Crusaders reconquer and sometimes conquer for the first time the polytheists of Arabia. These Arab polytheists had to convert to Islam or die. They did not have the choice of remaining in their faith and paying a tax. Islam does not allow for religious freedom.

633 The Muslim Crusaders, led by Khalid al-Walid, a superior but bloodthirsty military commander, whom Muhammad nicknamed the Sword of Allah for his ferocity in battle (Tabari, 8:158 / 1616-17), conquer the city of Ullays along the Euphrates River (in today’s Iraq). Khalid captures and beheads so many that a nearby canal, into which the blood flowed, was called Blood Canal (Tabari 11:24 / 2034-35).

634 At the Battle of Yarmuk in Syria the Muslim Crusaders defeat the Byzantines. Today Osama bin Laden draws inspiration from the defeat, and especially from an anecdote about Khalid al-Walid. An unnamed Muslim remarks: “The Romans are so numerous and the Muslims so few.” To this Khalid retorts: “How few are the Romans, and how many the Muslims! Armies become numerous only with victory and few only with defeat, not by the number of men. By God, I would love it . . . if the enemy were twice as many” (Tabari, 11:94 / 2095). Osama bin Ladin quotes Khalid and says that his fighters love death more than we in the West love life. This philosophy of death probably comes from a verse like Sura 2:96. Muhammad assesses the Jews: “[Prophet], you are sure to find them [the Jews] clinging to life more eagerly than any other people, even polytheists” (MAS Abdel Haleem, The Qur’an, Oxford UP, 2004; first insertion in brackets is Haleem’s; the second mine).

So, let's consider these simple questions. Were the Crusades an unprovoked assault by the Christian world upon Islam, or a Christian response to a long train of attacks and assaults upon Christian nations, Christian institutions, and Christian people? Is the anti-Christian rhetoric of Osama and the Islamists a response to the Crusades, or a true expression of Islam that dates back to its foundation?

I believe the above makes the answers quite obvious.
