Fact check
AI analysis“In 1095, the Catholic Church launched the Crusades.”
Reasoning
Pope Urban II’s 1095 speech, letter, and council decree explicitly called for a holy war to reclaim Jerusalem, which scholars identify as the official launch of the First Crusade. While the military campaign began the following year, the Church’s launch action occurred in 1095.
On confidence: Multiple primary sources and independent scholarly works confirm the papal call in 1095 as the formal initiation of the First Crusade, though the actual expedition departed in 1096.
Important context
The Crusades refer to a series of campaigns; the claim pertains to the initiation of the First Crusade. The papal proclamation in 1095 marked the launch, but the forces mobilized in 1096, and the impetus also involved Byzantine appeals for aid.

Limitations
